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] Currently, during the use of printer ink cartridges, the cartridge chip stores data that typically records the ink level, usage count, and matching information between the printer and the cartridge. However, with long-term use, the ink count data in the chip can reach a set threshold, causing the printer to mistakenly determine that the cartridge is no longer usable. Even if there is still ink left in the cartridge, the user is forced to replace the cartridge. This not only increases usage costs but also wastes resources.

[0003] To extend the life of ink cartridges and reduce replacement costs, various ink cartridge chip reset solutions have emerged on the market. However, existing methods have significant limitations in adaptability, primarily due to poor compatibility with different brands and models of ink cartridges. Traditional reset technologies often rely on a single communication method, resulting in a low success rate for ink cartridge chip resets. Summary of the Invention

[0004] 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.

[0005] A direct resetting device for an ink cartridge chip, wherein the ink cartridge chip is attached to the ink cartridge body, and the direct resetting device for the ink cartridge chip comprises:

[0006] A base, wherein a display control mechanism is provided on one side of the base;

[0007] A fixing platform, located on the base and used for mounting and cooperating with the ink cartridge body;

[0008] a pre-tightening component, located on one side of the fixing platform and movably abutting against one side of the ink cartridge body, so as to pre-tighten the ink cartridge body and the fixing platform;

[0009] a support platform, located on the other side of the fixed platform, and hingedly equipped with a reset communication board, the reset communication board being arranged on the fixed platform via a movable cover hingedly equipped with the support platform, the reset communication board being detachably connected to a near-field communication element or a contact abutment element, and when the reset communication board is engaged with the fixed platform cover, the near-field communication element or the contact abutment element performs data communication with the ink cartridge chip;

[0010] The reset communication board is electrically connected to the display control mechanism.

[0011] By adopting the above technical solution and designing removable near-field communication components and contact abutment components on the reset communication board, the device can flexibly adapt 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 wirelessly interact with the chip for data exchange, avoiding problems such as poor contact, wear and aging that may occur with traditional physical contacts, thereby improving the stability of the reset. For cartridge chips using wired communication protocols such as I²C and SPI, contact abutment components can be installed to precisely connect the chip data port through physical contacts to ensure the stability and reliability of data transmission. This replaceable communication module design not only supports cartridge chips of different brands, models, and communication protocols, but can also quickly adapt to new cartridge chip architectures based on 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 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 ease of use, and thus provides users with a more flexible, efficient and stable ink cartridge chip reset solution.

[0012] Preferably, a limiting groove is provided on the reset communication board, and a communication contact is provided on the limiting groove. When the near-field communication element or the contact abutment element is installed on the limiting 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.

[0013] By adopting the above technical solution, the positioning grooves ensure that the NFC component or contact abutment component can be accurately installed on the reset communication board, and a stable electrical connection can be established through the communication contacts. Because the communication contacts are directly connected to the NFC component or contact abutment component, the reset communication board can more accurately obtain communication data from the ink 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 device and making the reset process more stable and efficient.

[0014] 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.

[0015] By adopting the above technical solution, the reset communication board integrates a main control unit, a multi-protocol compatibility unit, a storage unit, and a USB interface unit, giving the device a higher level of intelligence and expansion capabilities. The main control unit works in conjunction with the multi-protocol compatibility unit to automatically adjust the communication mode according to different ink cartridge chip communication protocols (such as NFC, I²C, SPI, etc.), improving device compatibility. The storage unit is used to store reset rules and historical data for different ink cartridge chips, enabling the device to perform intelligent resets based on preset rules, ensuring the rationality and stability of data modifications. The USB interface unit provides a data exchange interface with external devices, enabling data updates or remote control via computers and other devices, thereby improving the reset device's functional expandability and maintainability.

[0016] 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 engaged with the threaded push rod, and a pre-tightening groove for mounting and cooperating with the ink cartridge body is provided on the fixed platform, 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 movably abut the ink cartridge body.

[0017] By adopting the above technical solution, the pre-tightening component, through the structural design of the support block, threaded groove, and threaded push rod, allows the ink cartridge to be stably fixed to the fixed platform. The adjustment function of the threaded push rod can also adapt to ink cartridge bodies of different sizes. The user can rotate the threaded push rod to move it toward the pre-tightening groove, thereby firmly abutting the ink cartridge body against the fixed platform, ensuring that the reset communication board maintains good contact with the ink cartridge chip, avoiding communication failures caused by looseness or poor contact. This design not only improves the device's adaptability to different ink cartridge models, but also improves the device's reset stability, making data transmission more accurate and reliable.

[0018] Preferably, the support platform includes a first support column and a second support column arranged at intervals, 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 placed on the second support column.

[0019] By adopting the above technical solution, the support platform utilizes a first support column and a second support column arranged at intervals, allowing the reset communication board to be fixed to the first support column via a hinged structure and mounted on the second support column at its other end. This design ensures that the reset communication board remains stable during use and can be easily removed and replaced when the near-field communication component or contact abutment component needs to be replaced, improving the device's maintenance convenience. Furthermore, this structure ensures that the reset communication board maintains stable contact with the ink cartridge chip when the cover is installed, thereby improving the reliability of the reset device and the reset success rate.

[0020] A direct ink cartridge chip reset method is applied to an ink cartridge chip direct reset device. The direct ink cartridge chip reset method includes:

[0021] Obtaining chip attribute data of the ink cartridge chip, and performing corresponding component connection prompt operations according to the chip attribute data;

[0022] Check whether the component connection prompt operation is responded successfully, if not, perform an alarm operation, if successful, real-time detection of whether a communication path has been established with the ink cartridge chip;

[0023] If a communication path has been established with the ink cartridge chip, the ink count data stored in the ink cartridge chip is read;

[0024] Based on a preset reset rule, the read ink count data is modified, and the modified data is written into the ink cartridge chip via a near field communication element or a contact abutment element;

[0025] 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 corresponding feedback operations based on the judgment result. The feedback operations include display operations, alarm operations, and remote push operations.

[0026] By employing this technical solution, during the reset process, the ink cartridge chip's chip attribute data is first acquired. Based on this chip attribute data, a component connection prompt is executed, allowing the user to intuitively determine whether the current reset device is correctly matched to the communication method applicable to the ink cartridge chip. This step ensures that before the reset, whether the reset communication board is correctly installed with the near-field communication component or contact abutment component can be determined, preventing reset failures due to incorrect connections, thereby improving the reset success rate and user experience.

[0027] Preferably, the step of obtaining chip attribute data of the ink cartridge chip and performing a corresponding component connection prompt operation according to the chip attribute data includes:

[0028] Extracting the communication type field of the chip attribute data;

[0029] Matching the communication type data corresponding to the communication type field based on a preset type mapping relationship;

[0030] A corresponding component connection prompt operation is performed according to the communication type data, wherein the component connection prompt operation includes a text display operation and a light flashing operation.

[0031] 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 determine the communication method applicable to the current ink cartridge chip. Based on the matching results, the system executes the corresponding component connection prompt operation, which includes text display operation and light flashing operation. Through the text display, the user can clearly understand the communication method required by the current ink cartridge chip, as well as the near-field communication component or contact abutment component that should be installed; through the light flashing operation, an intuitive status indication can be provided, allowing the user to quickly determine whether the device is correctly connected to the required communication module. This technical solution improves the intelligent interactive capability of the reset device, ensuring that the user can obtain clear guidance during the operation process, thereby reducing the risk of connection errors and improving the adaptability and ease of use of the reset device.

[0032] Preferably, the step of checking whether the component connection prompt operation is successfully responded to, if not, performing an alarm operation, and if successful, detecting in real time whether a communication path has been established with the ink cartridge chip is specifically as follows:

[0033] After the user installs the near field communication component or the contact abutment component on the reset communication board, a self-test step between the reset communication board and the near field communication component or the contact abutment component;

[0034] The self-test steps include:

[0035] Send corresponding communication requests in real time;

[0036] detecting whether corresponding self-test data is received, wherein the self-test data is data generated and sent by the near field communication component or the contact abutment component after receiving the communication request, and is used to determine whether the component connection prompt operation is responded to successfully;

[0037] Determine whether the self-test data matches the communication request successfully. If not, execute the corresponding alarm operation. If successful, generate corresponding inspection data according to the communication request, and detect in real time whether a communication path has been established with the ink cartridge chip. The inspection data is used to detect whether a communication path has been established with the ink cartridge chip.

[0038] By adopting the above technical solution, during the process of verifying whether the component connection prompt operation has successfully responded, the self-test step between the reset communication board and the near-field communication component or the contact abutment component is performed to quickly detect the component connection status. By sending a communication request in real time and detecting whether the self-test data returned by the near-field communication component or the contact abutment component has been received, it can be determined whether the current connection is normal. If no valid self-test data is detected, an alarm operation is executed to prompt the user to adjust or replace the component; if a successful matching self-test data is detected, the communication path with the ink cartridge chip is continued to be tested. This step improves the device's adaptability, ensuring that the connection status of each component is correct during the reset process, thereby avoiding reset failures caused by abnormal connections.

[0039] Preferably, the step of detecting in real time whether a communication path has been established with the ink cartridge chip includes:

[0040] Calling the standby time threshold of the inspection data;

[0041] When the component connection prompt operation response is successful, the timing starts, and 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;

[0042] If the user has already placed the reset communication board cover on the fixed platform, then calling the handshake request for the verification data;

[0043] detecting whether handshake response data is received, wherein the handshake response data is data generated and sent by the ink cartridge chip after receiving the handshake request and used to determine whether a communication path has been established with the ink cartridge chip;

[0044] If the handshake response data is received, it is determined that a communication path has been established with the ink cartridge chip.

[0045] By adopting the above technical solution, during the process of verifying whether the component connection prompt operation has successfully responded, the self-test step between the reset communication board and the near-field communication component or the contact abutment component is performed to quickly detect the component connection status. By sending a communication request in real time and detecting whether the self-test data returned by the near-field communication component or the contact abutment component has been received, it can be determined whether the current connection is normal. If no valid self-test data is detected, an alarm operation is executed to prompt the user to adjust or replace the component; if a successful matching self-test data is detected, the communication path with the ink cartridge chip is continued to be tested. This step improves the device's adaptability, ensuring that the connection status of each component is correct during the reset process, thereby avoiding reset failures caused by abnormal connections.

[0046] Preferably, the step of modifying the read ink count data includes:

[0047] Selecting a corresponding preset reset rule, wherein the preset reset rule includes a first reset rule, a second reset rule, and a third reset rule;

[0048] Based on a first reset rule, the ink count data is set to a default full value;

[0049] Based on a second reset rule, a corresponding ratio value is calculated according to historical usage data of the ink cartridge chip, and the ink count data is adjusted to the corresponding ratio value;

[0050] Based on the third reset rule, a dynamic adjustment rule is added to enable the ink cartridge chip to update the ink count data in a decrementing manner set by the dynamic adjustment rule during subsequent use.

[0051] By adopting the above technical solution, in the process of modifying the ink count data, the preset reset rules provide a variety of data adjustment strategies to adapt to the needs of different types of ink cartridge chips and printers. The first reset rule directly sets the ink count data to the default full value, so that the ink cartridge can be recognized as a brand new ink cartridge by the printer after reset, thereby resuming 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 the proportional value, so that the state of the ink cartridge after reset is closer to the actual usage, reducing the possibility of abnormality detected by the printer. The third reset rule introduces a dynamic adjustment rule, so that the ink cartridge chip gradually updates the ink count data according to the set decreasing method during subsequent use, thereby simulating the actual ink consumption state and avoiding abnormality detected by the printer due to direct reset 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 enhance the rationality and concealment of the reset data.

[0052] In summary, this application includes at least one of the following beneficial technical effects:

[0053] This application designs detachable near-field communication components and contact abutment components on the reset communication board, so that the device can flexibly adapt to different types of ink cartridge chips, significantly improving the compatibility and adaptability of the reset device. For ink cartridge chips that use 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 caused by device limitations, improves the reset success rate and ease of use, and thus provides users with a more flexible, efficient and stable ink cartridge chip reset solution.

DETAILED DESCRIPTION

[0063] The present application is further described in detail below with reference to the accompanying drawings.

[0064] In one embodiment, if Figure 1 As shown, the present application discloses a direct reset device for an ink cartridge chip, wherein the ink cartridge chip is attached to the ink cartridge body 100. The direct reset device for the ink cartridge chip includes:

[0065] A base 1, with a display control mechanism 2 provided on one side of the base 1;

[0066] The fixing platform 3 is located on the base 1 and is used for mounting and cooperating with the ink cartridge body 100;

[0067] The pre-tightening component 4 is located on one side of the fixing platform 3 and is movably in contact with one side of the ink cartridge body 100 to pre-tighten the ink cartridge body 100 and the fixing platform 3;

[0068] The support platform 5 is located on the other side of the fixed platform 3 and is hingedly equipped with a reset communication board 6. The reset communication board 6 is movably mounted on the fixed platform 3 by hingedly engaging with the support platform 5. The reset communication board 6 is detachably connected to a near-field communication element or a contact abutment element. When the reset communication board 6 is engaged with the fixed platform 3, the near-field communication element or the contact abutment element communicates data with the ink cartridge chip.

[0069] The reset communication board 6 is electrically connected to the display control mechanism 2 .

[0070] 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 realize functions such as fixation, reset, data exchange, and user feedback during operation. The base 1 is set at the bottom of the device and serves as the support 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 foundation for the reset process.

[0071] A pre-tightening component 4 is mounted 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 are tightly fitted together, ensuring that the ink cartridge does not become loose during operation and affect the stability of data communication. The pre-tightening component 4 typically includes a certain adjustment mechanism to accommodate ink cartridges of different specifications, thereby improving the compatibility and adaptability of the device. The support platform 5 is located on the other side of the fixed platform 3 and is movably connected to the reset communication board 6 via a hinged structure. This hinged connection allows the reset communication board 6 to be flexibly opened and closed, allowing it to be securely mounted on the fixed platform 3 during operation and easily opened when components need to be installed, removed, or replaced, thereby improving the maintainability and ease of use of the device.

[0072] The reset communication board 6 is the core of the device, equipped with a removable near-field communication component or contact abutment component, making it compatible with ink cartridge chips using different communication methods. When the device needs to exchange data with an ink cartridge chip that supports NFC communication, the user can install the near-field communication component to enable wireless data communication. When the device needs to interact with an ink cartridge chip using a wired communication protocol such as I²C or SPI, the contact abutment component can be installed to enable data transmission through physical contact. This replaceable communication module design allows the reset device to be compatible with ink cartridge chips of different brands and different communication protocols, improving the device's versatility and applicability. It can also adapt to new ink cartridge chip technologies that may emerge in the future through simple component replacement, ensuring the device's upgradeability.

[0073] When the reset communication board 6 is mated with the fixed platform 3, the near field communication element or the contact abutment element will be docked with the ink cartridge chip, thereby establishing a stable data communication channel to ensure that data can be accurately read and written during the reset process, and reset failure will not occur due to poor contact or incorrect communication mode. 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.

[0074] The overall structure of the device is provided with stable support by 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.

[0075] Figure 1 The 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 it is covered with the fixing platform 3.

[0076] In summary, by designing detachable near-field communication components and contact abutment components on the reset communication board 6, the device can flexibly adapt to different types of ink cartridge chips, significantly improving the compatibility and adaptability of the reset device. For ink cartridge chips that use 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 caused by device limitations, improves the reset success rate and ease of use, and thus provides users with a more flexible, efficient and stable ink cartridge chip reset solution.

[0077] Further, such as Figure 2 As shown, a limit slot 61 is provided on the reset communication board 6, and a communication contact 62 is provided on the limit slot 61. When the near-field communication element or the contact abutment element is installed on the limit slot 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.

[0078] In this embodiment, the reset communication board 6 serves as the core control unit of the reset device, and a limiting slot 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 slot 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 slot 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, thereby avoiding data transmission failure due to component position offset or poor contact. The structure of the limiting slot 61 has been 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 misalignment during the use of the reset communication board 6, thereby improving the long-term reliability of the entire device.

[0079] When the near-field communication element or the contact abutment element is installed in the limiting groove 61, a contact-type electrical connection is formed between the communication contact 62 on the limiting 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 ink cartridge chips that use NFC wireless communication, after the near-field communication element is installed in the limiting groove 61, it can establish an electrical connection with the reset communication board 6 through the communication contact 62, and send data requests or receive response data to the ink cartridge chip through wireless signals. For ink cartridge chips that use wired communication protocols such as I²C and SPI, after the contact abutment element is installed in the limiting groove 61, it can directly form 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.

[0080] 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, in combination with the reset logic in the storage unit 65, identifies and modifies the ink count data stored in the ink cartridge chip. After the modification is completed, the main control unit 63 will select a suitable communication method through the multi-protocol compatible unit 64, and 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 to achieve the count reset of the ink cartridge chip and ensure that the ink cartridge can continue to be used.

[0081] During the data transmission process, communication contacts 62 function not only as a data transmission interface but also provide feedback on the installation status of the components through the electrical connection status. If communication contacts 62 detect an abnormal electrical connection status of the near-field communication component or the contact abutment component, the reset communication board 6 can provide a prompt to the user through the display control mechanism 2, reminding the user to adjust or reinstall the communication component to avoid reset failure caused by poor connection. At the same time, the reset communication board 6 can use an internal detection mechanism to determine whether the current communication method matches the communication protocol of the ink cartridge chip. If not, it will prompt the user to replace the communication component to ensure the accuracy and stability of the entire reset process.

[0082] Through this structural design, reset communication board 6 can flexibly adapt near-field communication components or contact abutment components to different ink cartridge chip types, and ensure the stability of data exchange through communication contacts 62. Main control unit 63 can parse and process data in real time, ultimately completing the modification of ink count data through the reset logic of storage unit 65. The data is then written back to the ink cartridge chip via multi-protocol compatibility unit 64, restoring the ink cartridge to a usable state. Communication contacts 62 are not only an interface for data transmission but also provide status monitoring and error feedback throughout the reset process, ensuring stable operation of the device across a variety of ink cartridge chips and communication environments, thereby improving reset success rate and compatibility.

[0083] 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.

[0084] 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 into the board body. The various units are connected through data communication terminals to ensure accurate transmission, storage, and interaction of data during the reset process. The multi-protocol compatible unit 64 is responsible for adapting to different communication methods. 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 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 data from the ink cartridge chip and process it through the multi-protocol compatible unit 64 to adapt to different communication protocols, including common data interaction methods such as NFC, I²C, and SPI.

[0085] 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 serves as the data control center of the entire reset process. Its main task is to parse the storage structure in the ink cartridge chip, determine the current ink count data, and modify 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 key information such as the reset algorithm, chip model correspondence, historical reset records, etc. 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.

[0086] After 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 reset 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. The first data communication terminal then sends the data to the near-field communication element or the contact abutment element through the communication contact 62, and finally completes 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, avoiding data loss or reset failure due to communication protocol mismatch or signal interference.

[0087] In addition, in order to improve the scalability 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 management software, allowing the user to 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 personalized adaptability. At the same time, the USB interface unit 66 can also serve as an interface for firmware upgrades, so that the reset device can update new reset algorithms and compatible data at any time, improving the long-term applicability of the device.

[0088] The entire system's workflow is centered around the main control unit 63, which adapts data transmission via the multi-protocol compatibility unit 64. Communication contacts 62 connect to near-field communication components or contact abutment components, enabling bidirectional communication with the ink cartridge chip. Furthermore, the storage unit 65 stores reset logic and manages historical data, ensuring the reset process complies with the technical requirements of different ink cartridge chips. The USB interface unit 66 provides external communication and system upgrade capabilities, enabling the device to adapt to more complex application scenarios. Through this interconnected relationship, the reset communication board 6 achieves highly intelligent data management, improving the accuracy and stability of the reset process, ensuring efficient operation in diverse environments, and ensuring long-term maintainability and scalability.

[0089] 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 fixing platform 3. The end of the threaded push rod 43 close to the fixing 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 the ink cartridge body 100.

[0090] In this embodiment, the pre-tightening component 4, which serves as a key structure for ensuring that the ink cartridge body 100 is stably mounted on the fixing platform 3, is composed of a support block 41, a threaded groove 42, and a threaded push rod 43. The various components are connected 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, providing stable support for the entire pre-tightening mechanism. At the same time, a threaded groove 42 is provided above it, allowing the threaded groove 42 to be firmly fixed on the support block 41, ensuring that the threaded push rod 43 can smoothly perform threaded movement within the threaded groove 42. The interior of the threaded groove 42 is provided with a threaded structure that tightly engages with the threaded teeth of the threaded push rod 43, allowing the threaded push rod 43 to move forward and backward along the axial direction of the threaded 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.

[0091] One end of the threaded push rod 43 is positioned adjacent to the mounting platform 3, and its end is aligned with a preload groove on the mounting platform 3. This allows the push rod 43 to gradually approach the ink cartridge body 100 as it moves toward the preload groove, ultimately contacting the outer shell of the ink cartridge body 100 and effectively securing it. During adjustment, the user can rotate the push rod 43 to axially advance or retreat within the threaded groove 42. As the push rod 43 advances, its end gradually enters the preload groove, firmly pressing the ink cartridge body 100 against the mounting platform 3. This ensures precise contact between the ink cartridge chip and the near-field communication components or contact abutment components on the reset communication board 6, preventing communication instability or data transmission failures caused by looseness or misalignment. To replace the ink cartridge, the user can reversely rotate the push rod 43, moving it away from the preload groove. This reduces the abutment pressure on the ink cartridge body 100, allowing for smooth removal of the ink cartridge, improving ease of operation and maintenance efficiency.

[0092] It ensures that the ink cartridge remains stable during the installation and resetting process, and avoids the ink cartridge from becoming loose due to external vibration or misoperation. At the same time, the threaded matching method of the threaded groove 42 and the threaded push rod 43 allows the user to accurately control the preload force to adapt to ink cartridge bodies 100 of different specifications and materials, thereby improving the compatibility and applicability 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, thereby improving the stability of data transmission, ensuring that the data of the ink cartridge chip can be correctly read and modified during the reset process, and improving 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.

[0093] Further, such as Figure 1 As shown, the support platform 5 includes a first support column 51 and a second support column 52 arranged at intervals. 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 .

[0094] In this embodiment, the support platform 5 is composed of a first support column 51 and a second support column 52, which are arranged at intervals. The interval between the two ensures that the reset communication board 6 can be stably installed and achieve reliable movable 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 allows 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 operating convenience and long-term reliability of the equipment. 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.

[0095] like Figure 4 As shown, a direct reset method for an ink cartridge chip is applied to a direct reset device for an ink cartridge chip. The direct reset method for an ink cartridge chip includes:

[0096] S10. Obtaining the chip attribute data of the ink cartridge chip and performing corresponding component connection prompt operations based on the chip attribute data. In this embodiment, obtaining the chip attribute data of the ink cartridge chip involves establishing a preliminary connection with the ink cartridge chip via the near-field communication component or contact abutment component on the reset communication board 6, and reading 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 method applicable to the current ink cartridge chip and automatically match the corresponding communication mode, providing reliable technical support for subsequent data transmission and modification. For example, when using an ink cartridge chip that communicates with NFC, the device will detect whether the wireless communication signal from the ink cartridge chip is successfully received. When using a wired communication method such as I²C or SPI, the feasibility of data transmission is verified through contact electrical connection. If the chip data can be successfully extracted, it means that the preliminary connection has been established. Otherwise, the ink cartridge installation position may need to be adjusted or the matching communication component may need to be replaced.

[0097] S20. Check whether the component connection prompt operation responds successfully. If not, perform an alarm operation. If successful, perform real-time detection of 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 attempt 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 the 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 adaptability 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.

[0098] S30: If a communication path has been established with the ink cartridge chip, the ink count data stored in the ink cartridge chip is read. In this embodiment, if a communication path has been established with the ink cartridge chip, reading the ink count data stored in the ink cartridge chip means, upon confirming that the communication path is stable, sending a read command to the ink cartridge chip via the established connection by the reset communication board 6, and parsing the returned data to obtain the ink count value stored within the chip. The technical effect of this step is to accurately extract the current status information of the ink cartridge, ensuring that subsequent reset operations can be performed in a targeted manner. For example, for ink cartridge chips using an EEPROM storage structure, the system will read the ink count value from a specific storage address and perform a data integrity check in conjunction with the chip's anti-tampering mechanism to ensure that the extracted data is authentic and valid.

[0099] S40. Modify the read ink count data based on preset reset rules and write the modified data to the ink cartridge chip via a near-field communication element or a contact abutment element. In this embodiment, modifying the read ink count data based on preset reset rules and writing the modified data to the ink cartridge chip via a near-field communication element or a contact abutment element means that the device adjusts the ink count value according to different reset rules based on the chip type and historical usage data, and stores the modified data back to the ink cartridge chip to achieve a reset operation. Reset rules can 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 decrement 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 minimizing the possibility of triggering the printer's anti-counterfeiting detection mechanism due to abnormal data modifications. For example, for certain ink cartridge chips with encryption protection, the system will recalculate its checksum field before writing the modified data to ensure that the reset data format complies with the chip's storage rules, thereby improving the stability and compatibility of the reset.

[0100] S50: Reread the ink count data stored in the ink cartridge chip, determine whether the write is successful, generate a corresponding judgment result, and perform corresponding feedback operations based on the judgment result. Feedback operations include display operations, alarm operations, and remote push operations. In this embodiment, rereading the ink count data stored in the ink cartridge chip, determining whether the write is successful, generating a corresponding judgment result, and performing corresponding feedback operations based on the judgment result. Feedback operations include display operations, alarm operations, and remote push operations. This 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 has not been written correctly, the system will trigger an alarm mechanism to remind the user that there may be a write failure and provide corresponding handling 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.

[0101] In one embodiment, if Figure 5 As shown, in step S10, i.e., obtaining the chip attribute data of the ink cartridge chip and performing the corresponding component connection prompt operation according to the chip attribute data, the steps include:

[0102] S101. Extract the communication type field of the chip attribute data; in this 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, avoiding 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.

[0103] S102. Matching the communication type data corresponding to the communication type field based on a preset type mapping relationship. In this embodiment, matching the communication type data corresponding to the communication type field based on a preset type mapping relationship means that after extracting the communication type field, the device compares the value of this field with the stored communication modes using a preset communication protocol mapping table within storage unit 65 to determine the communication type actually supported by the current ink cartridge chip. This preset mapping relationship includes a list of communication protocols for different brands and models of ink cartridge chips and can be dynamically updated based on different versions of each manufacturer to ensure the accuracy of the matching results. The technical effect of this step is that the reset device can quickly adapt to different types of ink cartridge chips, improving the compatibility of the reset system and avoiding reset failures caused by manually selecting the wrong communication mode. For example, if the communication type field value extracted by the device is a brand-specific SPI variant protocol, and this protocol is marked as "Special SPI" in the mapping relationship table, the device will automatically adjust the timing parameters of data exchange to ensure that subsequent data read and write operations are executed correctly.

[0104] S103. Execute the corresponding component connection prompt operation based on the communication type data. 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 based on the communication type data. The component connection prompt operation includes a text display operation and a light flashing operation. This 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 current ink cartridge chip's communication method requires the use of a near-field communication component, the device's display will display a prompt message "NFC mode" and the indicator light will flash 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 uses I²C or SPI communication methods, the device will display a prompt message "Contact mode" and guide the user to install or adjust the contact abutment component. The technical effect of this step is to reduce communication connection failures caused by user operation errors and improve the device's ease of use and interactive experience. 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 by flashing a red indicator light and an error message, thereby ensuring that the reset process can proceed smoothly.

[0105] 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, performing an alarm operation, and if successful, real-time detection of whether a communication path has been established with the ink cartridge chip is specifically as follows:

[0106] After the user installs the near field communication element or the contact abutment element on the reset communication board 6, a self-test step is performed between the reset communication board 6 and the near field communication element or the contact abutment element;

[0107] The self-test steps include:

[0108] 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 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, after 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.

[0109] S2012: Detecting whether the corresponding self-test data has been received. The self-test data is data generated and sent by the near-field communication component or the contact abutment component after receiving a communication request to determine whether the component connection prompt operation has responded successfully. In this embodiment, detecting whether the corresponding self-test data has been received means that after the reset communication board 6 sends the communication request, it monitors whether the near-field communication component or the contact abutment component returns the response data as expected, and checks whether the data meets the format requirements of the self-test data. Self-test data is feedback information generated and sent by the near-field communication component or the contact abutment component after receiving a test command. The data is used to indicate whether the current connection status and function of the component 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 operational 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 component, the device will wait for the component to return a unique device identifier within a short period of time. If the returned data format is correct, it indicates that the component 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 component.

[0110] S2013: Determine whether the self-test data successfully matches the communication request. If not, execute the corresponding alarm operation. If successful, generate corresponding test data based on the communication request and detect in real time whether a communication path has been established with the cartridge chip. The test data is used to detect whether a communication path has been established with the cartridge chip. In this embodiment, detecting whether the corresponding self-test data has been received means that after sending the communication request, the reset communication board 6 monitors whether the near-field communication component or the contact abutment component returns response data as expected, and checks whether the data conforms to the format requirements of the self-test data. Self-test data is feedback information generated and sent by the near-field communication component or the contact abutment component after receiving the test command. This data is used to indicate whether the current connection status and function of the component are normal. The technical effect of this step is to ensure that the physical connection and data transmission capabilities of the communication module meet operational 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 component, the device will wait for the component to return a unique device identifier within a short period of time. If the returned data format is correct, it indicates that the component 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 component.

[0111] In one embodiment, if Figure 7 As shown, in step S20, i.e., the step of detecting in real time whether a communication path has been established with the ink cartridge chip, the following steps are included:

[0112] S2021. Recalling the standby time threshold for verification data. In this embodiment, the standby time threshold for verification data refers to the process by which the reset communication board 6 retrieves a preset standby time threshold from the storage unit 65 after detecting that the user has installed a near-field communication component or a contact contact component and responding successfully to the component connection prompt operation. This threshold is used to set the maximum waiting time for the current device to establish a communication path. This standby time threshold is used to prevent the system from being in a waiting state for a long time, which would waste resources, while ensuring that the device can complete communication detection or execute the corresponding error handling strategy within a reasonable time frame. The technical effect of this step is to improve the operating efficiency of the system and prevent the device from waiting indefinitely, which would affect the normal operation of the subsequent reset process. For example, if the system's preset standby time threshold is 30 seconds, the device will continuously attempt to establish a communication path with the ink cartridge chip within this time frame. However, if a connection is not successfully established after 30 seconds, the system will execute the corresponding exception handling process instead of waiting indefinitely.

[0113] S2022. When the component connection prompt operation response is successful, the timing starts. If the standby time threshold is not exceeded, the standby operation is executed. If the standby time threshold is exceeded, the shutdown operation is executed. In this embodiment, when the component connection prompt operation response is successful, the timing starts. If the standby time threshold is not exceeded, the standby operation is executed. If the standby time threshold is exceeded, the shutdown operation is executed. This means that after the device successfully confirms that the near-field communication component or the contact abutment component is correctly installed, it immediately starts the internal timer and continuously monitors the system running time during the entire detection process. If the communication path is still not successfully established within the standby time threshold, the system will execute the standby operation to keep the device in a low-power 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 ink cartridge chip but fails to receive an effective response, if the user does not intervene or adjust it 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.

[0114] S2023. If the user has already placed the reset communication board 6 on the fixed platform 3, a handshake request for verifying data is called. In this embodiment, if the user has already placed the reset communication board 6 on the fixed platform 3, calling a handshake request for verifying data means that when the device detects that the reset communication board 6 is in the appropriate placement position, it automatically sends a handshake request to the ink cartridge chip to attempt to establish a formal communication path. A handshake request is typically a set of signal instructions for initializing data transmission, which includes a device identifier, communication protocol negotiation information, and an authentication code for establishing a secure connection to ensure that a data interaction relationship can be successfully established between the reset communication board 6 and the ink cartridge chip. 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.

[0115] S2024, detecting whether handshake response data is received, the handshake response data is the data generated and sent by the ink cartridge chip after receiving 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 the data generated and sent by the ink cartridge chip after receiving 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 correctly docked, or the ink cartridge chip is damaged, thereby providing corresponding user prompt information.

[0116] S2025. If handshake response data is received, it is determined that a communication path has been established with the ink cartridge chip. In this embodiment, if handshake response data is received, determining that a communication path has been established with the ink cartridge chip means that, after successfully verifying the handshake response data, the device confirms that the data exchange channel with the ink cartridge chip has been officially established and enters the subsequent data reading or writing process. At this point, the device can access the data stored in the ink cartridge chip through the established communication path, including but not limited to ink count, number of prints, 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 operations, thereby avoiding data loss or storage corruption caused by unstable communication or incorrect connection. For example, in I²C mode, the device may send a read command to retrieve data from a specific storage address and confirm that the communication path is successfully established after receiving a valid response. In NFC mode, the device may first need to detect the chip's anti-collision identifier to confirm that the currently connected device is unique and ensure that communication errors are not caused by multiple chips responding simultaneously.

[0117] In one embodiment, if Figure 8 As shown, in step S30, that is, the step of modifying the read ink count data, the steps include:

[0118] S301. Select the corresponding preset reset rule, which 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 different 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. For ordinary ink cartridge chips, the first reset rule can be directly selected to maximize the restoration of its service life.

[0119] S302. Based on the first reset rule, the ink count data is set 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 its 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 end. For example, in some printer systems, the count data of the ink cartridge chip is stored in the EEPROM. 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 operate normally.

[0120] S303. Based on the second reset rule, the corresponding ratio value is calculated according to the historical usage data of the ink cartridge chip, and the ink count data is adjusted to the corresponding ratio value. In this embodiment, based on the second reset rule, the corresponding ratio value is calculated according to the historical usage data of the ink cartridge chip, and the ink count data is adjusted to the corresponding ratio value. This 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 based on 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 the ink cartridge as abnormal due to detecting 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 history, the system will calculate the ink count value to be restored based on the set ratio, rather than directly returning to 100%, and may adjust it 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.

[0121] S304: Based on the third reset rule, a dynamic adjustment rule is added to cause the ink cartridge chip to update the ink count data in a decremental manner according to the dynamic adjustment rule during subsequent use. In this embodiment, based on the second reset rule, a corresponding ratio value is calculated based on the historical usage data of the ink cartridge chip, and the ink count data is adjusted to the corresponding ratio value. This 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 based on 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, preventing the printer from determining that the ink cartridge is abnormal due to detecting a sudden change in the ink count, and improving the stealth 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 based on the set ratio, rather than 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 normal use of the ink cartridge.
