Description

Technical Field

[0001] The present invention relates to the technical field of ink cartridge chip resetting, and in particular to an ink cartridge chip direct resetting device and method. Background Art

[0002] At present, during the use of printer ink cartridges, the storage data of the ink cartridge chip is usually used to record the ink remaining, the number of times it is used, and the matching information between the printer and the ink cartridge. However, with the long-term use of the ink cartridge, the ink count data in the chip will reach the set threshold, causing the printer to misjudge that the ink cartridge can no longer be used. Even if there is still remaining ink in the ink cartridge, the user has to replace the new ink cartridge. This not only increases the cost of use, but also causes a waste of resources; Therefore, in order to extend the service life of ink cartridges and reduce the cost of replacing consumables, a variety of ink cartridge chip reset solutions have appeared on the market. However, the existing ink cartridge chip reset methods have significant deficiencies in adaptability, mainly reflected in the poor compatibility with different brands and models of ink cartridges. Traditional reset technology often relies on a single communication method, resulting in a low success rate of ink cartridge chip reset. Summary of the invention

[0003] In order to solve the problem of low reset success rate caused by poor compatibility of traditional ink cartridge chip reset solutions, the present application provides an ink cartridge chip direct reset device and method.

[0004] A direct resetting device for an ink cartridge chip, wherein the ink cartridge chip is attached to an ink cartridge body, and the direct resetting device for the ink cartridge chip comprises: A base, wherein a display control mechanism is provided on one side of the base; A fixing platform, located on the base and used for mounting and cooperating with the ink cartridge body; A pre-tightening component is located at one side of the fixing platform and movably abuts against one side of the ink cartridge body so as to pre-tighten the ink cartridge body and the fixing platform; The support platform is located at the other side of the fixed platform and is hingedly matched with a reset communication board. The reset communication board is movably covered on the fixed platform by hingedly matching with the support platform. A near field communication element or a contact abutment element is detachably connected to the reset communication board. When the reset communication board is matched with the fixed platform cover, the near field communication element or the contact abutment element performs data communication with the ink cartridge chip. The reset communication board is electrically connected to the display control mechanism.

[0005] By adopting the above technical solution, by designing a detachable near-field communication component and a contact abutment component on the reset communication board, the device can be flexibly adapted to different types of cartridge chips, significantly improving the compatibility and adaptability of the reset device. For cartridge chips using NFC technology, users can install near-field communication components to interact with the chip wirelessly, avoiding problems such as poor contact, wear and aging that may occur with traditional physical contacts, thereby improving the stability of reset. For cartridge chips using wired communication protocols such as I²C and SPI, contact abutment components can be installed to accurately connect the chip data port through physical contacts to ensure the stability and reliability of data transmission. This replaceable communication module design can not only support cartridge chips of different brands, models, and communication protocols, but also quickly adapt to new cartridge chip architectures according to market demand. There is no need to replace the entire reset device, only the corresponding communication module needs to be replaced to achieve compatibility, greatly improving the versatility and upgrade and expansion capabilities of the equipment. Compared with traditional reset devices that only support a single communication method, this design effectively solves the incompatibility between different communication protocols, reduces reset failures due to device limitations, improves reset success rate and ease of use, and thus provides users with a more flexible, efficient and stable cartridge chip reset solution.

[0006] Preferably, a limit groove is provided on the reset communication board, and a communication contact is provided on the limit groove. When the near-field communication element or the contact abutment element is installed on the limit groove, the communication contact is electrically connected to the near-field communication element or the contact abutment element, so that the reset communication board obtains corresponding communication data through the near-field communication element or the contact abutment element.

[0007] By adopting the above technical solution, the setting of the limit groove enables the near-field communication element or the contact abutment element to be accurately installed on the reset communication board and to be stably electrically connected through the communication contacts. Since the communication contacts are directly connected to the near-field communication element or the contact abutment element, the reset communication board can more accurately obtain the communication data from the cartridge chip, ensuring the stability and accuracy of data transmission. This design avoids reset failures caused by component installation position deviations or poor contact, thereby improving the reliability of the equipment and making the reset process more stable and efficient.

[0008] Preferably, the reset communication board includes a board body, and a main control unit, a multi-protocol compatible unit, a storage unit and a USB interface unit located in the board body, the first data communication end of the multi-protocol compatible unit is electrically connected to the communication contact, the second data communication end of the multi-protocol compatible unit is connected to the first data communication end of the main control unit, the second data communication end of the main control unit is connected to the data communication end of the storage unit, and the third data communication end of the main control unit is connected to the data communication end of the USB interface unit.

[0009] By adopting the above technical solution, the reset communication board integrates the main control unit, the multi-protocol compatible unit, the storage unit and the USB interface unit, so that the device has a higher level of intelligence and expansion capabilities. The main control unit cooperates with the multi-protocol compatible unit to automatically adjust the communication mode according to different ink cartridge chip communication protocols (such as NFC, I²C, SPI, etc.) to improve the compatibility of the device. The storage unit is used to store the reset rules and historical data of different ink cartridge chips, so that the device can perform intelligent reset based on preset rules to ensure the rationality and stability of data modification. The USB interface unit provides a data interaction interface for external devices, so that the device can update data or remotely control through computers and other devices, thereby improving the functional expandability and maintainability of the reset device.

[0010] Preferably, the pre-tightening component includes a support block, a threaded groove and a threaded push rod, the threaded groove, the support block and the base are connected in sequence from top to bottom, the threaded groove is threadedly matched with the threaded push rod, the fixed platform is provided with a pre-tightening groove for mounting and matching with the ink cartridge body, the end of the threaded push rod close to the fixed platform is arranged corresponding to the pre-tightening groove, and the threaded push rod moves relative to the threaded groove in a direction close to or away from the pre-tightening groove so as to be used to flexibly abut against the ink cartridge body.

[0011] By adopting the above technical solution, the pre-tightening component can stably fix the ink cartridge on the fixed table through the structural design of the support block, thread groove and threaded push rod, and adapt to the ink cartridge body of different sizes through the adjustment function of the threaded push rod. The user can rotate the threaded push rod to move it in the direction of the pre-tightening groove, so as to firmly abut the ink cartridge body on the fixed table, ensure that the reset communication board maintains good contact with the ink cartridge chip, and avoid communication failure caused by looseness or poor contact. This design not only improves the adaptability of the device to different ink cartridge models, but also improves the reset stability of the device, making data transmission more accurate and reliable.

[0012] Preferably, the support platform comprises a first support column and a second support column which are spaced apart from each other, the first support column is hingedly engaged with one end of the reset communication board, and the other end of the reset communication board is mounted on the second support column.

[0013] By adopting the above technical solution, the support platform is arranged with the first support column and the second support column spaced apart, so that the reset communication board can be fixed on the first support column through the hinge structure and the other end is placed on the second support column. This design can ensure that the reset communication board remains stable during use and can be easily disassembled and replaced when the near-field communication component or the contact abutting component needs to be replaced, improving the maintenance convenience of the device. In addition, this structure can ensure that the reset communication board maintains stable contact with the ink cartridge chip when covering, thereby improving the reliability and reset success rate of the reset device.

[0014] A method for directly resetting an ink cartridge chip, which is applied to a device for directly resetting an ink cartridge chip, the method for directly resetting an ink cartridge chip includes: Obtain the chip attribute data of the ink cartridge chip, and perform corresponding component connection prompt operations according to the chip attribute data; Check whether the component connection prompt operation responds successfully. If it does not respond successfully, perform an alarm operation. If it responds successfully, detect in real time whether a communication path has been established with the ink cartridge chip; If a communication path has been established with the ink cartridge chip, read the ink count data stored in the ink cartridge chip; Based on a preset reset rule, modify the read ink count data, and write the modified data into the ink cartridge chip through a near-field communication component or a contact abutting component; Read the ink count data stored in the ink cartridge chip again, judge whether the writing is successful, generate a corresponding judgment result, and perform corresponding feedback operations according to the judgment result. The feedback operations include display operations, alarm operations, and remote push operations.

[0015] By adopting the above technical solution, during the reset process, first obtain the chip attribute data of the ink cartridge chip, and perform component connection prompt operations according to the chip attribute data, enabling the user to intuitively judge whether the current reset device correctly matches the communication method applicable to the ink cartridge chip. This step ensures that before the reset, it can be judged whether the correct near-field communication component or contact abutting component is installed on the reset communication board, avoiding reset failure caused by incorrect connection, thereby improving the success rate of the reset operation and the user experience.

[0016] Preferably, in the step of obtaining the chip attribute data of the ink cartridge chip and performing corresponding component connection prompt operations according to the chip attribute data, it includes: Extract the communication type field of the chip attribute data; Based on a preset type mapping relationship, match the communication type data corresponding to the communication type field; Perform corresponding component connection prompting operations according to the communication type data, where the component connection prompting operations include text display operations and lamp flashing operations.

[0017] By adopting the above technical solution, after obtaining the chip attribute data of the ink cartridge chip, the system first extracts the communication type field therein to identify the specific communication protocol used by the ink cartridge chip. Subsequently, based on the preset type mapping relationship, the communication type data corresponding to the communication type field is matched to ensure that the system can correctly judge the applicable communication method of the current ink cartridge chip. Based on the matching result, the system performs corresponding component connection prompting operations, including text display operations and lamp flashing operations. Through text display, the user can clearly understand the communication method required by the current ink cartridge chip and the near-field communication component or contact abutment component that should be installed; through the lamp flashing operation, an intuitive status indication can be provided, enabling the user to quickly judge whether the device is correctly connected to the required communication module. This technical solution improves the intelligent interaction ability of the reset device, ensures that the user can obtain clear guidance during the operation, thereby reducing the risk of connection errors, and improving the adaptability and usability of the reset device.

[0018] Preferably, the step of checking whether the component connection prompting operation responds successfully. If it does not respond successfully, an alarm operation is performed. If it responds successfully, the step of detecting whether a communication path has been established with the ink cartridge chip in real time is specifically as follows: After the user installs the near-field communication component or contact abutment component on the reset communication board, the self-check step between the reset communication board and the near-field communication component or contact abutment component; The self-check step includes: Send corresponding communication requests in real time; Detect whether corresponding self-check data is received. The self-check data is data generated and sent by the near-field communication component or contact abutment component after receiving the communication request to determine whether the component connection prompting operation responds successfully; Judge whether the self-check data matches the communication request successfully. If it is not successful, perform the corresponding alarm operation. If it is successful, generate corresponding verification data according to the communication request, and detect in real time whether a communication path has been established with the ink cartridge chip. The verification data is used to detect whether a communication path has been established with the ink cartridge chip.

[0019] By adopting the above technical solution, during the process of checking whether the component connection prompt operation responds successfully, the self-check step between the reset communication board and the near-field communication component or the contact abutting component is reset to achieve rapid detection of the component connection status. By sending a communication request in real time and detecting whether self-check data returned by the near-field communication component or the contact abutting component is received, it can be determined whether the current connection is normal. If no valid self-check data is detected, an alarm operation is performed to prompt the user to adjust or replace the component; if self-check data with a successful match is detected, the communication path with the ink cartridge chip is continuously detected. This step improves the adaptive ability of the device, ensures the correct connection status of each component during the reset process, and thus avoids reset failure caused by abnormal connection.

[0020] Preferably, in the step of detecting in real time whether a communication path has been established with the ink cartridge chip, it includes: Invoking the standby duration threshold of the inspection data; When the component connection prompt operation responds successfully, start timing. If the standby duration threshold is not exceeded, perform a standby operation; if the standby duration threshold is exceeded, perform a shutdown operation; If the user has covered the reset communication board on the fixed table, then invoke the handshake request of the inspection data; Detect whether handshake response data is received. The handshake response data is data generated and sent by the ink cartridge chip after receiving the handshake request for determining whether a communication path has been established with the ink cartridge chip; If handshake response data is received, it is determined that a communication path has been established with the ink cartridge chip.

[0021] By adopting the above technical solution, during the process of checking whether the component connection prompt operation responds successfully, the self-check step between the reset communication board and the near-field communication component or the contact abutting component is reset to achieve rapid detection of the component connection status. By sending a communication request in real time and detecting whether self-check data returned by the near-field communication component or the contact abutting component is received, it can be determined whether the current connection is normal. If no valid self-check data is detected, an alarm operation is performed to prompt the user to adjust or replace the component; if self-check data with a successful match is detected, the communication path with the ink cartridge chip is continuously detected. This step improves the adaptive ability of the device, ensures the correct connection status of each component during the reset process, and thus avoids reset failure caused by abnormal connection.

[0022] Preferably, in the step of modifying the read ink count data, it includes: Select a corresponding preset reset rule. The preset reset rules include a first reset rule, a second reset rule, and a third reset rule; Based on the first reset rule, set the ink count data to the default full value; Based on the second reset rule, calculate the corresponding proportional value according to the historical usage data of the ink cartridge chip, and adjust the ink count data to the corresponding proportional value; Based on the third reset rule, add a dynamic adjustment rule to enable the ink cartridge chip to update the ink count data in a decreasing manner set by the dynamic adjustment rule during subsequent use.

[0023] By adopting the above technical solutions, during the process of modifying the ink count data, the preset reset rules provide a variety of data adjustment strategies to adapt to different types of ink cartridge chips and printer requirements. The first reset rule directly sets the ink count data to the default full value, enabling the ink cartridge to be recognized as a brand-new ink cartridge by the printer after reset, thus restoring normal use. The second reset rule calculates a reasonable proportional value based on the historical usage data of the ink cartridge chip and adjusts the ink count to this proportional value, making the state of the ink cartridge after reset closer to the actual usage situation and reducing the possibility of being detected as abnormal by the printer. The third reset rule introduces a dynamic adjustment rule, enabling the ink cartridge chip to gradually update the ink count data in a set decreasing manner during subsequent use, thereby simulating the actual ink consumption state and avoiding being detected as abnormal by the printer due to directly resetting to the full value. This multi-mode reset strategy improves the adaptability of the reset device, enabling it to meet the needs of different users and enhancing the rationality and concealment of the reset data.

[0024] In summary, the present application includes at least one of the following beneficial technical effects: By designing a detachable near-field communication component and a contact abutment component on the reset communication board, the present application enables the device to flexibly adapt to different types of ink cartridge chips, significantly improving the compatibility and adaptability of the reset device. For ink cartridge chips using NFC technology, users can install the near-field communication component to interact with the chip wirelessly, avoiding problems such as poor contact and wear and aging that may occur in traditional physical contacts, thereby improving the stability of reset. For ink cartridge chips using wired communication protocols such as I²C and SPI, the contact abutment component can be installed to accurately dock with the chip data port through physical contacts, ensuring the stability and reliability of data transmission. This replaceable communication module design can not only support ink cartridge chips of different brands, models, and communication protocols, but also quickly adapt to new ink cartridge chip architectures according to market demands. Without replacing the entire reset device, only the corresponding communication module needs to be replaced to achieve compatibility, greatly improving the versatility and upgrade expansion ability of the device. Compared with traditional reset devices that only support a single communication method, this design effectively solves the incompatibility between different communication protocols, reduces reset failures caused by device limitations, improves the reset success rate and usage convenience, and thus provides a more flexible, efficient, and stable ink cartridge chip reset solution for users.

Detailed Description of the Embodiment

[0027] The following further describes the present application in detail with reference to the drawings.

[0028] In an embodiment, as Figure 1 shown, the present application discloses a direct reset device for a cartridge chip, wherein the cartridge chip is attached to the cartridge body 100. A direct reset device for a cartridge chip includes: A base 1, with a display control mechanism 2 provided on one side of the base 1; A fixing table 3, located on the base 1 and used for installation and cooperation with the cartridge body 100; A pre - tightening component 4, located on one side of the fixing table 3 and movably abutting against one side of the cartridge body 100 to make the cartridge body 100 and the fixing table 3 in pre - tightened cooperation; The support platform 5 is located at the other side of the fixed platform 3 and is hingedly matched with a reset communication board 6. The reset communication board 6 is movably covered on the fixed platform 3 by hingedly matching with the support platform 5. A near field communication element or a contact abutment element is detachably connected to the reset communication board 6. When the reset communication board 6 is matched with the fixed platform 3, the near field communication element or the contact abutment element communicates data with the ink cartridge chip. The reset communication board 6 is electrically connected to the display control mechanism 2 .

[0029] In this embodiment, the device as a whole is composed of multiple structural parts that cooperate with each other to form a stable reset system. Each structural part is connected through a specific port, so that the device can achieve functions such as fixation, reset, data interaction, and user feedback during operation. The base 1 is set at the bottom of the device as a supporting structure of the entire device to ensure the stability of the device. At the same time, a display control mechanism 2 is set on one side of the base 1, so that the user can view the device status, reset progress and related operation prompts in real time through the display interface. The fixing platform 3 is located above the base 1, and the shape and size of the fixing platform 3 are adapted to the ink cartridge body 100, so that the ink cartridge body 100 can be stably placed on the fixing platform 3 and installed with it, thereby providing a stable operating basis for the reset process.

[0030] A pre-tightening component 4 is installed on one side of the fixed platform 3. The function of the pre-tightening component 4 is to apply appropriate pressure to the ink cartridge body 100 through a certain mechanical mechanism, so that the ink cartridge body 100 and the fixed platform 3 can be closely matched, ensuring that the ink cartridge will not be loose during operation and affect the stability of data communication. The pre-tightening component 4 usually includes a certain adjustment mechanism to adapt to ink cartridges of different specifications to improve the compatibility and adaptability of the device. The support platform 5 is located on the other side of the fixed platform 3, and the support platform 5 and the reset communication board 6 are movably connected through a hinge structure. This hinged matching method allows the reset communication board 6 to be flexibly opened and closed, and can be stably covered on the fixed platform 3 when the device is running, and can be conveniently opened when it is necessary to install, disassemble or replace components, thereby improving the maintainability and ease of use of the device.

[0031] The reset communication board 6 is the core part of the device, on which a detachable near-field communication element or a contact abutment element is arranged, so that the device can be compatible with ink cartridge chips of different communication modes. When the device needs to interact with an ink cartridge chip supporting NFC communication, the user can install a near-field communication element to enable it to complete data communication wirelessly, and when the device needs to interact with an ink cartridge chip using wired communication protocols such as I²C and SPI, a contact abutment element can be installed to enable it to achieve data transmission through physical contact. This replaceable communication module design enables the reset device to be applicable to ink cartridge chips of different brands and different communication protocols, thereby improving the versatility and scope of application of the device. At the same time, it can also adapt to new ink cartridge chip technologies that may appear in the future through simple component replacement, thereby ensuring the upgradeability of the device.

[0032] When the reset communication board 6 is matched with the fixed platform 3 cover, the near field communication element or the contact abutment element will be connected with the ink cartridge chip, thereby establishing a stable data communication channel to ensure that the data can be accurately read and written during the reset process, and the reset failure will not be caused by poor contact or communication mode errors. The electrical port of the reset communication board 6 is connected to the display control mechanism 2 through a circuit, so that during the reset process, the device can obtain the status information of the ink cartridge chip in real time, and provide intuitive operation feedback on the display control mechanism 2, including the current reset progress, the reset success or failure status, and possible error prompts, so that the user can adjust the operation in time to improve the accuracy and success rate of the reset. In addition, the electrical connection between the reset communication board 6 and the display control mechanism 2 also allows the user to select different reset modes through the display interface, such as directly resetting the ink cartridge count to the full value, or adjusting the ink count according to a certain ratio, so as to meet the needs of different ink cartridge models and different printer systems, and enhance the intelligence level of the device.

[0033] The overall structure of the device provides stable support through the base 1, the fixing platform 3 and the pre-tightening component 4 ensure that the ink cartridge body 100 is fixed, the hinged cooperation between the support platform 5 and the reset communication board 6 improves the flexibility of operation, and the detachable near-field communication element or contact abutment element on the reset communication board 6 provides multi-protocol compatibility, so that the device can adapt to ink cartridge chips with various different communication methods. During the reset process, through the electrical connection between the reset communication board 6 and the display control mechanism 2, the user can clearly obtain the device status, select a suitable reset strategy, and confirm the reset result, thereby improving the stability, compatibility and intelligence level of the reset device and realizing efficient reset of ink cartridge chips of different brands and models.

[0034] Figure 1 A near field communication component is installed, and the part where the contact abutment component is inconsistent with the near field communication component is that there is a corresponding electrode protrusion on the side close to the ink cartridge chip when the fixing platform 3 is covered.

[0035] In summary, by designing a detachable near-field communication component and a contact abutment component on the reset communication board 6, the device can be flexibly adapted to different types of ink cartridge chips, significantly improving the compatibility and adaptability of the reset device. For ink cartridge chips using NFC technology, users can install near-field communication components to interact with the chip wirelessly, avoiding problems such as poor contact, wear and aging that may occur with traditional physical contacts, thereby improving the stability of the reset. For ink cartridge chips that use wired communication protocols such as I²C and SPI, contact abutment components can be installed to accurately connect the chip data port through physical contacts to ensure the stability and reliability of data transmission. This replaceable communication module design can not only support ink cartridge chips of different brands, models, and communication protocols, but also quickly adapt to new ink cartridge chip architectures according to market demand. There is no need to replace the entire reset device, only the corresponding communication module needs to be replaced to achieve compatibility, which greatly improves the versatility and upgrade and expansion capabilities of the equipment. Compared with traditional reset devices that only support a single communication method, this design effectively solves the incompatibility between different communication protocols, reduces reset failures due to device limitations, improves reset success rate and ease of use, and thus provides users with a more flexible, efficient and stable cartridge chip reset solution.

[0036] Further, such as Figure 2 As shown, a limit groove 61 is provided on the reset communication board 6, and a communication contact 62 is provided on the limit groove 61. When the near-field communication element or the contact abutment element is installed on the limit groove 61, the communication contact 62 is electrically connected to the near-field communication element or the contact abutment element, so that the reset communication board 6 obtains corresponding communication data through the near-field communication element or the contact abutment element.

[0037] In this embodiment, the reset communication board 6 serves as the core control unit of the reset device, and a limiting groove 61 is provided on the reset communication board 6, so that the near field communication element or the contact abutment element can be installed in the limiting groove 61 in a detachable manner, thereby ensuring that different types of communication elements can be stably connected to the reset communication board 6 and perform data exchange. The function of the limiting groove 61 is to provide a precise installation area, so that the near field communication element or the contact abutment element can be fixed in the correct position and maintain a stable electrical connection, avoiding data transmission failure due to component position displacement or poor contact. The structure of the limiting groove 61 is precisely designed, so that it can provide a certain positioning effect during installation, and prevent the near field communication element or the contact abutment element from loosening or misaligning during the use of the reset communication board 6, thereby improving the long-term reliability of the entire device.

[0038] When the near field communication element or the contact abutment element is installed in the limit groove 61, a contact-type electrical connection is formed between the communication contact 62 on the limit groove 61 and the near field communication element or the contact abutment element. This electrical connection method ensures the stability of data transmission, so that the reset communication board 6 can obtain communication data from the ink cartridge chip through the near field communication element or the contact abutment element. The function of the communication contact 62 is to serve as an interface for data transmission, so that the reset communication board 6 can complete data interaction according to different communication methods. For the ink cartridge chip using NFC wireless communication mode, after the near field communication element is installed in the limit groove 61, it can establish an electrical connection with the reset communication board 6 through the communication contact 62, and send a data request to the ink cartridge chip or receive response data through a wireless signal. For the ink cartridge chip using wired communication protocols such as I²C and SPI, after the contact abutment element is installed in the limit groove 61, it can directly form a physical electrical contact with the reset communication board 6 through the communication contact 62, and transmit data with the ink cartridge chip in a wired manner, ensuring the stability and efficiency of data interaction.

[0039] After receiving the data from the communication contact 62, the reset communication board 6 will transmit the data to the internal main control unit 63 for parsing and processing. After parsing the data, the main control unit 63 identifies and modifies the ink count data stored in the ink cartridge chip in combination with the reset logic in the storage unit 65. After the modification is completed, the main control unit 63 will select a suitable communication method through the multi-protocol compatible unit 64, send the modified data back to the near-field communication element or the contact abutment element through the communication contact 62, and finally write it into the ink cartridge chip. The whole process ensures the two-way flow of data, so that the reset communication board 6 can not only read data from the ink cartridge chip, but also write the reset data to the ink cartridge chip, so as to achieve the count reset of the ink cartridge chip and ensure that the ink cartridge can continue to be used.

[0040] During the data transmission process, the communication contact 62 not only serves as an interface for data transmission, but also can provide feedback on the installation status of the component through the state of the electrical connection. If the communication contact 62 detects that the electrical connection status of the near-field communication component or the contact abutment component is abnormal, the reset communication board 6 can provide prompt information to the user through the display control mechanism 2, reminding the user to adjust or reinstall the communication component to avoid reset failure due to poor connection. At the same time, the reset communication board 6 can determine whether the current communication mode matches the communication protocol of the ink cartridge chip through the internal detection mechanism, and prompt the user to replace the communication component if it does not match, so as to ensure the accuracy and stability of the entire reset process.

[0041] Through this structural design, the reset communication board 6 can flexibly adapt the near field communication element or the contact abutment element according to different ink cartridge chip types, and ensure the stability of data interaction through the communication contact 62. The main control unit 63 can parse and process the data in real time, and finally complete the modification of the ink count data through the reset logic of the storage unit 65, and write the data back to the ink cartridge chip through the multi-protocol compatible unit 64 to restore the ink cartridge to a usable state. The communication contact 62 is not only an interface for data transmission, but also can provide status monitoring and error feedback during the entire reset process, ensuring that the device can operate stably in various ink cartridge chips and communication environments, and improving the success rate and compatibility of the reset.

[0042] Further, such as Figure 2-Figure 3 As shown, the reset communication board 6 includes a board body, and a main control unit 63, a multi-protocol compatible unit 64, a storage unit 65 and a USB interface unit 66 located in the board body. The first data communication end of the multi-protocol compatible unit 64 is electrically connected to the communication contact 62, the second data communication end of the multi-protocol compatible unit 64 is connected to the first data communication end of the main control unit 63, the second data communication end of the main control unit 63 is connected to the data communication end of the storage unit 65, and the third data communication end of the main control unit 63 is connected to the data communication end of the USB interface unit 66.

[0043] In this embodiment, the reset communication board 6 serves as the core control unit of the entire reset device. The main control unit 63, the multi-protocol compatible unit 64, the storage unit 65 and the USB interface unit 66 are integrated in the board body. The various units are connected through the data communication terminal to ensure the accurate transmission, storage and interaction of data during the reset process. The multi-protocol compatible unit 64 assumes the function of adapting to different communication modes. Its first data communication terminal is electrically connected to the communication contact 62 to ensure that both the near field communication element and the contact abutment element can establish a stable electrical connection with the reset communication board 6 through the communication contact 62. The role of the communication contact 62 is not only to realize the data transmission at the physical layer, but also to undertake the task of data format conversion, so that the reset communication board 6 can accurately receive the data of the ink cartridge chip and process it through the multi-protocol compatible unit 64 to adapt to different communication protocols, including NFC, I²C, SPI and other common data interaction methods.

[0044] When the multi-protocol compatible unit 64 receives data from the ink cartridge chip through the communication contact 62, the data will be transmitted to the first data communication terminal of the main control unit 63 through its second data communication terminal, and will be parsed and processed by the main control unit 63. The main control unit 63, as the data control center of the entire reset process, has the main task of parsing the storage structure in the ink cartridge chip, judging the current ink count data, and modifying the data according to the preset reset logic. In order to ensure the accuracy and adaptability of the reset, the main control unit 63 needs to combine the reset rules and historical data in the storage unit 65 for calculation and judgment. Therefore, the second data communication terminal of the main control unit 63 is connected to the data communication terminal of the storage unit 65, so that the main control unit 63 can read the reset algorithm, chip model correspondence, historical reset records and other key information from the storage unit 65, and update the data of the storage unit 65 when necessary to optimize the reset parameters and improve the compatibility of ink cartridge chips of different brands and models.

[0045] When the main control unit 63 completes the modification of the data, it needs to retransmit the modified data back to the ink cartridge chip to achieve the reset of the ink count. At this time, the main control unit 63 will transmit the modified data to the second data communication terminal of the multi-protocol compatible unit 64 through its first data communication terminal, and select the appropriate communication protocol through the multi-protocol compatible unit 64, and then the first data communication terminal will send the data to the near-field communication element or the contact abutment element through the communication contact 62, and finally complete the data writing, so that the counting data of the ink cartridge chip is restored to a state that complies with the reset rules. In this process, the multi-protocol compatible unit 64 not only undertakes the task of adapting the data protocol, but is also responsible for ensuring the stability and accuracy of data transmission, and avoiding data loss or reset failure due to communication protocol mismatch or signal interference.

[0046] In addition, in order to improve the expansibility and remote management capabilities of the reset device, the third data communication terminal of the main control unit 63 is connected to the data communication terminal of the USB interface unit 66, so that the device can exchange data with external devices through the USB interface. The function of the USB interface unit 66 is to provide a high-speed and stable external communication channel, so that the main control unit 63 can exchange data with a computer or other external control device, thereby realizing functions such as batch reset, remote data update, and historical record storage. During use, the USB interface unit 66 can be used to connect to the PC-side management software, so that the user can manage the data of different models of ink cartridge chips on the computer, and adjust the reset parameters when necessary to improve the accuracy of the reset and the personalized adaptation capability. At the same time, the USB interface unit 66 can also be used as an interface for firmware upgrades, so that the reset device can update new reset algorithms and compatible data at any time, thereby improving the long-term applicability of the device.

[0047] The workflow of the entire system is centered on the main control unit 63, which is adapted for data transmission through the multi-protocol compatible unit 64, and connected to the near-field communication element or the contact abutment element through the communication contact 62 to communicate bidirectionally with the ink cartridge chip. At the same time, the storage unit 65 provides storage of reset logic and historical data management to ensure that the reset process meets the technical requirements of different ink cartridge chips, while the USB interface unit 66 provides external communication and system upgrade functions, allowing the device to adapt to more complex application scenarios. Through this connection relationship, the reset communication board 6 can achieve highly intelligent data management, improve the accuracy and stability of the reset process, ensure that the device can operate efficiently in different environments, and have long-term maintainability and expansion capabilities.

[0048] Further, such as Figure 2 As shown, the pre-tightening component 4 includes a support block 41, a threaded groove 42 and a threaded push rod 43. The threaded groove 42, the support block 41 and the base 1 are connected in sequence from top to bottom. The threaded groove 42 is threadedly matched with the threaded push rod 43. A pre-tightening groove for mounting and matching with the ink cartridge body 100 is provided on the fixed platform 3. The end of the threaded push rod 43 close to the fixed platform 3 is arranged corresponding to the pre-tightening groove. The threaded push rod 43 moves relative to the threaded groove 42 in a direction close to or away from the pre-tightening groove so as to be used for movably abutting against the ink cartridge body 100.

[0049] In this embodiment, the pre-tightening component 4 is a key structure to ensure that the ink cartridge body 100 is stably mounted on the fixing platform 3, and is composed of a support block 41, a thread groove 42 and a threaded push rod 43. The various components are connected to each other through precise mechanical connections to achieve an adjustable fixing function. The support block 41 serves as the supporting base of the entire pre-tightening component 4. Its bottom is connected to the base 1 to provide a stable support for the entire pre-tightening mechanism. At the same time, a thread groove 42 is provided above it, so that the thread groove 42 can be firmly fixed on the support block 41, ensuring that the threaded push rod 43 can smoothly perform threaded matching movement in the thread groove 42. The thread groove 42 is provided with a threaded structure inside, which is tightly engaged with the thread teeth of the threaded push rod 43, so that the threaded push rod 43 can move forward and backward along the axial direction of the thread groove 42 without radial deviation, ensuring that the push rod can accurately apply a pre-tightening force to the ink cartridge body 100, thereby achieving a stable abutment effect.

[0050] One end of the threaded push rod 43 is close to the fixing platform 3, and its end is arranged corresponding to the pre-tightening groove on the fixing platform 3, so that when the threaded push rod 43 moves in the direction of the pre-tightening groove, its end can gradually approach the ink cartridge body 100, and finally contact the shell of the ink cartridge body 100, forming an effective compression fixation. During the adjustment process, the user can rotate the threaded push rod 43 to make it move forward or backward axially in the threaded groove 42. When the threaded push rod 43 is pushed forward, its end will gradually enter the pre-tightening groove, so that the ink cartridge body 100 is stably pressed on the fixing platform 3, thereby ensuring the contact accuracy between the ink cartridge chip and the near field communication element or contact abutment element on the reset communication board 6, avoiding communication instability or data transmission failure caused by looseness or position deviation. When the ink cartridge needs to be replaced, the user can reversely rotate the threaded push rod 43 to move it away from the pre-tightening groove, thereby reducing the abutment pressure on the ink cartridge body 100, so that the ink cartridge can be smoothly taken out, and the operation convenience and maintenance efficiency of the equipment are improved.

[0051] It ensures that the ink cartridge remains stable during installation and resetting, and avoids the ink cartridge from loosening due to external vibration or misoperation. At the same time, the threaded matching mode of the threaded groove 42 and the threaded push rod 43 enables the user to accurately control the preload force to adapt to the ink cartridge body 100 of different specifications and materials, thereby improving the compatibility and scope of application of the device. In addition, through the fine-tuning ability of the threaded push rod 43, it can ensure that the ink cartridge chip and the data communication module on the reset communication board 6 are reliably connected, improve the stability of data transmission, ensure that the data of the ink cartridge chip can be correctly read and modified during the reset process, and improve the success rate and reliability of the reset. This structure not only improves the fixing performance of the equipment, but also ensures the precise connection between the ink cartridge and the reset system, so that the entire device can operate efficiently in different environments and meet the reset requirements of different types of ink cartridges.

[0052] Further, such as Figure 1 As shown, the support platform 5 includes a first support column 51 and a second support column 52 that are spaced apart. The first support column 51 is hingedly engaged with one end of the reset communication board 6 , and the other end of the reset communication board 6 is placed on the second support column 52 .

[0053] In this embodiment, the support platform 5 is composed of a first support column 51 and a second support column 52 arranged at an interval, and the interval between the two ensures that the reset communication board 6 can be stably installed and achieve reliable active cooperation. The main function of the first support column 51 is to provide a hinge fulcrum for the reset communication board 6, so that one end of the reset communication board 6 can open and close around the hinge point, and the hinged cooperation method enables the reset communication board 6 to be flexibly opened when components need to be replaced, equipment maintenance or ink cartridge installation is required, and can be firmly closed during the reset operation, thereby improving the convenience of operation of the equipment and the reliability of long-term use. The hinge port of the first support column 51 and one end of the reset communication board 6 adopt a hinge structure or a rotating shaft structure, so that the reset communication board 6 can move along a fixed path when opened, avoiding position deviation, improving the stability and accuracy of the mechanical structure, and ensuring that the data communication module can always maintain the best contact state with the ink cartridge chip, thereby ensuring the stability of data reading and writing.

[0054] like Figure 4 As shown, a method for directly resetting an ink cartridge chip is applied to a device for directly resetting an ink cartridge chip. The method for directly resetting an ink cartridge chip includes: S10, obtaining the chip attribute data of the ink cartridge chip, and performing the corresponding component connection prompt operation according to the chip attribute data; in this embodiment, obtaining the chip attribute data of the ink cartridge chip means establishing a preliminary connection with the ink cartridge chip by resetting the near field communication element or the contact abutment element on the communication board 6, and reading the basic information about the ink cartridge chip from the chip storage unit 65, including but not limited to the chip model, storage structure, communication protocol type, manufacturer identification and current ink count value. The technical effect of this step is to ensure that the reset device can accurately identify the communication mode applicable to the current ink cartridge chip, and automatically match the corresponding communication mode, so as to provide reliable technical support for subsequent data transmission and modification. For example, when using an ink cartridge chip for NFC communication, the device will detect whether the wireless communication signal from the ink cartridge chip is successfully received, and in the case of using a wired communication method such as I²C or SPI, the feasibility of data transmission will be verified by means of contact electrical connection. If the chip data can be successfully extracted, it means that the preliminary connection has been established, otherwise it may be necessary to adjust the ink cartridge installation position or replace the matching communication element.

[0055] S20, check whether the component connection prompt operation responds successfully. If not, perform an alarm operation. If successful, detect in real time whether a communication path has been established with the ink cartridge chip. In this embodiment, checking whether the component connection prompt operation responds successfully means that after the system reads the chip attribute data, it will further detect whether the currently selected communication method matches the ink cartridge chip, and try to establish a valid data interaction path through real-time communication. If the system fails to detect a valid response from the ink cartridge chip, it will perform an alarm operation, including displaying an error message on the screen, flashing a device indicator light, or sounding an alarm, to remind the user to check the connection status of the ink cartridge, reinstall the ink cartridge, or replace the communication module. The technical effect of this step is to prevent data transmission failures caused by mismatched communication methods or poor connections, and to improve the adaptive ability of the reset device. For example, if the ink cartridge chip uses the I²C communication protocol, and the user installs an NFC module, the device will immediately prompt to replace the correct communication module to avoid subsequent data reading and writing failures.

[0056] S30, if a communication path has been established with the ink cartridge chip, then read the ink count data stored in the ink cartridge chip; in this embodiment, if a communication path has been established with the ink cartridge chip, then reading the ink count data stored in the ink cartridge chip means that, under the premise of confirming that the communication path is stable, the reset communication board 6 sends a read command to the ink cartridge chip through the established connection method, and parses the returned data to obtain the ink count value stored inside the chip. The technical effect of this step is to accurately extract the current status information of the ink cartridge to ensure that the subsequent reset operation can be carried out in a targeted manner. For example, for an ink cartridge chip using an EEPROM storage structure, the system will read the ink count value from a specific storage address, and perform data integrity verification in combination with the chip's anti-tampering mechanism to ensure that the extracted data is authentic and valid.

[0057] S40, based on the preset reset rule, modify the read ink count data, and write the modified data into the ink cartridge chip through the near field communication element or the contact abutment element; in this embodiment, based on the preset reset rule, modify the read ink count data, and write the modified data into the ink cartridge chip through the near field communication element or the contact abutment element, which means that the device adjusts the ink count value according to the chip type and historical usage data according to different reset rules, and stores the modified data back into the ink cartridge chip to achieve the reset operation. The reset rule may include directly resetting the ink count value to the default full value, adjusting it to a certain value according to a specific ratio, or setting a dynamic decreasing mode so that the chip simulates a normal ink consumption trend during subsequent use. The technical effect of this step is to ensure that the reset ink cartridge can be normally recognized by the printer, while avoiding the triggering of the printer's anti-counterfeiting detection mechanism due to abnormal data modification as much as possible. For example, for some ink cartridge chips with encryption protection, the system will recalculate its check field before writing the modified data to ensure that the data format after reset complies with the storage rules of the chip, thereby improving the stability and compatibility of the reset.

[0058] S50, re-read the ink count data stored in the ink cartridge chip, determine whether the writing is successful, generate a corresponding judgment result, and perform a corresponding feedback operation according to the judgment result, and the feedback operation includes a display operation, an alarm operation, and a remote push operation. In this embodiment, re-reading the ink count data stored in the ink cartridge chip, determining whether the writing is successful, generating a corresponding judgment result, and performing a corresponding feedback operation according to the judgment result, and the feedback operation includes a display operation, an alarm operation, and a remote push operation means that after the data is written, the system will send a read command to the ink cartridge chip again, and compare it with the value before the modification to verify whether the reset operation is successful. If it is detected that the data has been successfully modified, the system will prompt the reset completion on the display control mechanism 2, and optionally push the reset log record to the remote server; if it is detected that the data is not correctly written, the system will trigger the alarm mechanism to remind the user that there may be a write failure, and provide corresponding processing suggestions. The technical effect of this step is to ensure the reliability of the reset result and provide intuitive user feedback so that the user can confirm whether the reset is successful at the first time. For example, if the system detects that the original count value remains after writing data, the chip may have a write protection mechanism. At this time, the system will prompt the user to replace the ink cartridge that supports reset or adjust the writing method to ensure the smooth progress of the reset operation.

[0059] In one embodiment, if Figure 5 As shown, in step S10, the chip attribute data of the ink cartridge chip is obtained, and the step of performing the corresponding component connection prompt operation according to the chip attribute data includes: S101. Extract the communication type field of the chip attribute data; in the present embodiment, extracting the communication type field of the chip attribute data refers to establishing a preliminary communication connection with the ink cartridge chip by resetting the near field communication element or the contact abutment element on the communication board 6, and extracting identification information about the communication method from the data structure stored inside the chip. The communication type field is used to indicate the communication protocol supported by the ink cartridge chip, such as I²C, SPI or NFC, so that the subsequent steps can accurately match the applicable communication method. The technical effect of this step is to ensure that the reset device can accurately identify the communication mode of the ink cartridge chip to avoid data reading failure or writing error due to mismatch of the communication protocol. For example, if the communication type field of the ink cartridge chip shows that it supports the I²C protocol, the device will give priority to the contact abutment element for physical connection, and will not mistakenly try to use the near field communication element for wireless data transmission.

[0060] S102, matching the communication type data corresponding to the communication type field based on the preset type mapping relationship; in this embodiment, matching the communication type data corresponding to the communication type field based on the preset type mapping relationship means that after the device extracts the communication type field, it uses the preset communication protocol mapping table in the storage unit 65 to compare the value of the field with the stored communication mode, so as to determine the communication type actually supported by the current ink cartridge chip. The preset mapping relationship contains a list of communication protocols for ink cartridge chips of different brands and models, and can be dynamically updated according to different versions of the manufacturer to ensure the accuracy of the matching result. The technical effect of this step is to enable the reset device to quickly adapt to different types of ink cartridge chips, improve the compatibility of the reset system, and avoid reset failure due to manual selection of the wrong communication mode. For example, if the communication type field value extracted by the device is a brand-specific SPI variant protocol, and the protocol has been marked as "special SPI" in the mapping relationship table, the device will automatically adjust the timing parameters of the data interaction to ensure that subsequent data reading and writing operations can be performed correctly.

[0061] S103. Execute the corresponding component connection prompt operation according to the communication type data, and the component connection prompt operation includes a text display operation and a light flashing operation. In this embodiment, the corresponding component connection prompt operation is executed according to the communication type data, and the component connection prompt operation includes a text display operation and a light flashing operation, which means that after determining the correct communication method, the device will provide intuitive prompt information to the user through the display control mechanism 2 to ensure that the user installs or replaces the appropriate communication component. If the communication method of the current ink cartridge chip requires the use of near-field communication components, the display screen of the device will display the prompt information of "NFC mode" and flash the indicator light at the same time to remind the user to check whether the near-field communication component is correctly installed; if the current ink cartridge chip adopts I²C or SPI communication method, the device will display the prompt information of "contact mode" and guide the user to install or adjust the contact abutment component. The technical effect of this step is to reduce the communication connection failure caused by user operation errors and improve the convenience of use and interactive experience of the device. For example, if a user mistakenly installs a contact abutment component on a cartridge chip that requires NFC communication, the device will detect the communication failure and remind the user to replace the correct component through a flashing red indicator light and an error message, thereby ensuring that the reset process can proceed smoothly.

[0062] In one embodiment, if Figure 6 As shown, in step S20, that is, checking whether the component connection prompt operation is responded successfully, if not, then executing the alarm operation, if the response is successful, then real-time detection of whether a communication path has been established with the ink cartridge chip is specifically as follows: After the user installs the near field communication element or the contact abutment element on the reset communication board 6, a self-test step between the reset communication board 6 and the near field communication element or the contact abutment element; The self-test steps include: S2011, sending the corresponding communication request in real time; in this embodiment, sending the corresponding communication request in real time means that after the reset communication board 6 detects that the user has installed the near field communication component or the contact abutment component, it actively sends a standardized test command to the component to verify whether it is correctly connected and can communicate normally with the reset system. The content of the test command usually includes a specific handshake signal or a device identification request to ensure that the reset communication board 6 can successfully receive the data returned by the component and further confirm the integrity of the communication link. The technical effect of this step is to provide an automated connection detection capability to avoid subsequent data transmission failures due to component installation errors or poor contact. For example, when the user installs the contact abutment component, the reset communication board 6 will send it a set of I²C or SPI communication initialization commands. If the component can correctly receive and make a preliminary response, it means that the connection status is normal, otherwise the system will enter the fault detection mode.

[0063] S2012, detect whether the corresponding self-test data is received, the self-test data is generated and sent by the near field communication element or the contact abutment element after receiving the communication request to determine whether the component connection prompt operation responds successfully; in this embodiment, detecting whether the corresponding self-test data is received means that after the reset communication board 6 sends the communication request, it monitors whether the near field communication element or the contact abutment element returns the response data as expected, and checks whether the data meets the format requirements of the self-test data. The self-test data is feedback information generated and sent by the near field communication element or the contact abutment element after receiving the test command, and the data is used to indicate whether the connection status and function of the current element are normal. The technical effect of this step is to ensure that the physical connection and data transmission capabilities of the communication module meet the operating requirements, thereby improving the stability and reliability of the device. For example, if the reset communication board 6 sends an NFC initialization command to the near field communication element, the device will wait for the element to return a unique device identifier in a short time. If the returned data format is correct, it indicates that the element has been successfully installed and can continue to be used, otherwise the device will prompt the user to check the connection status or replace the element.

[0064] S2013, determine whether the self-test data matches the communication request successfully, if not, perform the corresponding alarm operation, if successful, generate corresponding test data according to the communication request, and detect in real time whether a communication path has been established with the ink cartridge chip, and the test data is used to detect whether a communication path has been established with the ink cartridge chip. In this embodiment, detecting whether the corresponding self-test data is received means that after the reset communication board 6 sends the communication request, it monitors whether the near field communication element or the contact abutment element returns the response data as expected, and checks whether the data meets the format requirements of the self-test data. The self-test data is feedback information generated and sent by the near field communication element or the contact abutment element after receiving the test command, and the data is used to indicate whether the connection status and function of the current element are normal. The technical effect of this step is to ensure that the physical connection and data transmission capabilities of the communication module meet the operating requirements, thereby improving the stability and reliability of the device. For example, if the reset communication board 6 sends an NFC initialization command to the near field communication element, the device will wait for the element to return a unique device identifier in a short time. If the returned data format is correct, it indicates that the element has been successfully installed and can continue to be used, otherwise the device will prompt the user to check the connection status or replace the element.

[0065] In one embodiment, if Figure 7 As shown, in step S20, i.e., the step of real-time detecting whether a communication path has been established with the ink cartridge chip, the following steps are included: S2021, calling the standby time threshold of the inspection data; in this embodiment, the standby time threshold of the inspection data refers to the reset communication board 6 extracting the preset standby time threshold from the storage unit 65 after detecting that the user has installed a near field communication element or a contact abutment element, and the element connection prompt operation response is successful, so as to set the maximum waiting time of the current device in the process of establishing a communication path. The standby time threshold is used to prevent the system from being in a waiting state for a long time, resulting in a waste of resources, and at the same time ensure that the device can complete the communication detection or execute the corresponding error handling strategy within a reasonable time range. The technical effect of this step is to improve the operating efficiency of the system and avoid the device from affecting the normal progress of the subsequent reset process due to unlimited waiting. For example, if the system presets a standby time threshold of 30 seconds, then within this time range, the device will continue to try to establish a communication path with the ink cartridge chip, but if the connection is not successfully established after more than 30 seconds, the system will execute the corresponding exception handling process instead of waiting indefinitely.

[0066] S2022. When the response to the component connection prompt operation is successful, the timing starts. If the standby time threshold is not exceeded, the standby operation is performed. If the standby time threshold is exceeded, the shutdown operation is performed. In this embodiment, when the response to the component connection prompt operation is successful, the timing starts. If the standby time threshold is not exceeded, the standby operation is performed. If the standby time threshold is exceeded, the shutdown operation is performed. It means that after the device successfully confirms that the near field communication component or the contact abutment component is correctly installed, the internal timer is immediately started, and the system operation time is continuously monitored during the entire detection process. If the communication path is still not successfully established within the standby time threshold, the system will perform a standby operation to keep the device in a low power consumption state to reduce energy consumption, and continue to try to establish a connection under subsequent possible user operation intervention; if the standby time exceeds the set threshold, the device will enter the shutdown process to avoid long-term idleness and occupation of system resources. The technical effect of this step is to ensure that the device can effectively manage energy consumption during the communication detection process, prevent unnecessary power consumption due to being in standby state for a long time, and improve the safety of the device. For example, when the system attempts to establish communication with the cartridge chip but fails to receive an effective response, if the user does not intervene or adjust in time, the device will automatically shut down after a set time period to prevent unnecessary standby power consumption and prevent the user from mistakenly believing that the device is still working and affecting subsequent operations.

[0067] S2023. If the user has already covered the reset communication board 6 on the fixed platform 3, then call the handshake request for verification data; in this embodiment, if the user has already covered the reset communication board 6 on the fixed platform 3, then calling the handshake request for verification data means that when the device detects that the reset communication board 6 is in a suitable covering position, it automatically sends a handshake request to the ink cartridge chip to try to establish a formal communication path. The handshake request is usually a set of signal instructions for initializing data transmission, which contains device identification, communication protocol negotiation information, and an authentication code for establishing a secure connection to ensure that the reset communication board 6 and the ink cartridge chip can successfully establish a data interaction relationship. The technical effect of this step is to ensure the integrity and security of data transmission while reducing the possibility of misoperation. For example, in NFC mode, the handshake request may use the standard ISO14443 protocol to send an initialization command, while in I²C or SPI mode, the device may need to first send an address query signal to the ink cartridge chip to verify whether the chip can respond normally, thereby confirming whether the communication channel is ready.

[0068] S2024, detecting whether handshake response data is received, the handshake response data is data generated and sent after the ink cartridge chip receives the handshake request to determine whether a communication path has been established with the ink cartridge chip; in this embodiment, detecting whether handshake response data is received, the handshake response data is data generated and sent after the ink cartridge chip receives the handshake request to determine whether a communication path has been established with the ink cartridge chip means that after sending the handshake request, the system monitors the return signal of the ink cartridge chip and determines whether it conforms to the expected response format. The handshake response data usually includes the chip's unique identifier, current storage status, and available communication parameters, so that the reset system can confirm the existence of the ink cartridge chip and obtain its necessary operating information. The technical effect of this step is to ensure that the device can accurately identify the current status of the ink cartridge chip, and adjust the subsequent data interaction mode according to the chip's feedback data, thereby improving the accuracy of the reset operation. For example, if the device receives valid response data containing the ink cartridge model and communication protocol information within the specified time after sending a handshake request, the handshake can be determined to be successful; if no valid data is received, the device may trigger a fault detection mechanism to determine whether the ink cartridge chip is not installed correctly, the communication module is not properly docked, or the ink cartridge chip is damaged, thereby providing corresponding user prompt information.

[0069] S2025. If the handshake response data is received, it is determined that a communication path has been established with the ink cartridge chip. In this embodiment, if the handshake response data is received, it is determined that a communication path has been established with the ink cartridge chip, which means that after the device successfully verifies the handshake response data, it confirms that the data interaction channel with the ink cartridge chip has been formally established, and enters the subsequent data reading or writing process. At this time, the device can access the data stored in the ink cartridge chip through the established communication path, including but not limited to the ink count value, the number of prints, the manufacturer information, etc., to provide data support for the subsequent reset operation. The technical effect of this step is to ensure that the reset system can confirm the stability and reliability of the communication path before performing any data modification operation, so as to avoid data loss or storage damage caused by unstable communication or wrong connection. For example, in I²C mode, the device may send a read instruction to obtain data from a specific storage address, and confirm that the communication path is successfully established after receiving a valid response, while in NFC mode, the device may need to first detect the anti-collision identifier of the chip to confirm whether the currently connected device is uniquely available and to ensure that there is no communication error caused by multiple chips responding at the same time.

[0070] In one embodiment, if Figure 8 As shown, in step S30, that is, the read ink count data is modified, the step includes: S301, select the corresponding preset reset rule, the preset reset rule includes the first reset rule, the second reset rule and the third reset rule; in this embodiment, selecting the corresponding preset reset rule means that after the reset communication board 6 reads the ink count data of the ink cartridge chip, it determines the reset method applicable to the current ink cartridge chip according to the reset strategy stored in the storage unit 65. The preset reset rules include the first reset rule, the second reset rule and the third reset rule, and each rule is optimized for different usage scenarios and printer compatibility requirements. The technical effect of this step is to improve the flexibility of the reset system, so that it can adapt to ink cartridge chips of different manufacturers and models, and minimize the risk of being detected as abnormal by the printer after reset. For example, if the ink cartridge chip adopts a strict ink remaining monitoring mechanism, the more hidden second or third reset rule can be selected to avoid being judged as an abnormal ink cartridge by the printer, and for ordinary ink cartridge chips, the first reset rule can be directly selected to restore its service life to the maximum extent.

[0071] S302, based on the first reset rule, setting the ink count data to the default full value; in this embodiment, based on the first reset rule, setting the ink count data to the default full value means that after the reset communication board 6 identifies the ink cartridge chip applicable to the first reset rule, it directly modifies the stored ink count value to the factory default full value, so that the printer recognizes that the ink cartridge is in a brand new state. The technical effect of this step is to enable the user to maximize the service life of the ink cartridge and keep the ink cartridge in a normal working state on the printer side. For example, in some printer systems, the count data of the ink cartridge chip is stored in the EEPROM, and the first reset rule will directly overwrite the corresponding count storage area in the EEPROM, so that its value is restored to the factory preset full value, such as 255 or 100%, so that the printer can re-identify the ink cartridge as a brand new, unused ink cartridge and continue to work normally.

[0072] S303, based on the second reset rule, according to the historical usage data of the ink cartridge chip, calculate the corresponding ratio value, and adjust the ink count data to the corresponding ratio value; in this embodiment, based on the second reset rule, according to the historical usage data of the ink cartridge chip, calculate the corresponding ratio value, and adjust the ink count data to the corresponding ratio value means that after reading the historical data of the ink cartridge chip, the reset communication board 6 calculates the adjustment range of the current ink count, and performs a moderate recovery according to the calculated ratio value, rather than directly resetting the ink count value to the full value. The technical effect of this step is to provide a more intelligent reset method, avoid the printer judging that the ink cartridge is abnormal due to the detection of a sudden change in the ink count, and improve the concealment and compatibility of the reset. For example, if the ink cartridge has printed 500 pages in the printer's historical record, the system will calculate the ink count value to be restored according to the set ratio, instead of directly returning to 100%, it may be adjusted to 80% or 90%, thereby simulating a more natural ink cartridge consumption state, making it easier for the printer to accept the reset data and continue to use the ink cartridge normally.

[0073] S304, based on the third reset rule, add a dynamic adjustment rule, so that the ink cartridge chip updates the ink count data in a decreasing manner set by the dynamic adjustment rule during subsequent use. In this embodiment, based on the second reset rule, according to the historical use data of the ink cartridge chip, the corresponding ratio value is calculated, and the ink count data is adjusted to the corresponding ratio value, which means that after the reset communication board 6 reads the historical data of the ink cartridge chip, it calculates the adjustment range of the current ink count and performs a moderate recovery according to the calculated ratio value, rather than directly resetting the ink count value to the full value. The technical effect of this step is to provide a more intelligent reset method, avoid the printer judging that the ink cartridge is abnormal due to the detection of a sudden change in the ink count, and improve the concealment and compatibility of the reset. For example, if the ink cartridge has printed 500 pages in the printer's historical record, the system will calculate the ink count value to be restored according to the set ratio, instead of directly returning to 100%, it may be adjusted to 80% or 90%, thereby simulating a more natural ink cartridge consumption state, making it easier for the printer to accept the reset data and continue to use the ink cartridge normally.
