Problems solved by technology

[0003] EPSON has launched a batch of models with hardware encryption ink cartridge control chips on the market. Due to the complexity of hardware encryption and decryption algorithms, the microcontroller (MCU) that supplies ink cartridges cannot complete data encryption and decryption within limited resources and time. Affect the working efficiency of the printer, therefore, the traditional MCU continuous supply scheme is difficult to be compatible with this type of models

Embodiment 1

[0026] figure 1 Shown is the architecture diagram of the system provided by the present invention, except the box body of the ink cartridge (not marked in the figure), the ink cartridge includes a control module with a built-in storage unit and a communication module 12 with a built-in storage unit, and the control module has a control function The electronic module can be MCU, DSP or CPU. In this embodiment, it is MCU11. MCU11 can be an 8-bit CMOS MCU with RISC structure, or an MCU with higher computing performance. In this embodiment, MCU11 is China Resources Silicon The company has the independent intellectual property rights of the single chip microcomputer CS8775 with EEPROM. The development platform adopts the CS8775 special assembly language development environment, which can directly generate the target file, and the target file can be directly written into the CS8775 through the CS8775 special burning device. The printer performs read and write operations on the commu...

Embodiment 2

[0035] The second embodiment of the present invention is described below. The second embodiment has the same ink cartridge structure as the first embodiment, but differs in the communication module 12. In the second embodiment, the communication module is an integrated multi-channel The ASIC chip, the ASIC chip has a plurality of channels respectively connected with a plurality of sensors, and a plurality of channels are connected with the bus of the printer interface circuit 13, and a plurality of discrete ASIC chips with similar functions are integrated on one chip, thereby reducing the chip volume, With the development of integrated circuit technology, the design complexity of integrated chips is only slightly increased compared with multiple discrete chips, and the manufacturing cost is actually lower.

Embodiment 3

[0037] Further, this embodiment provides a method for resetting the ink volume, including the following steps:

[0038] Step S11, setting a control module with a built-in storage unit in the ink cartridge;

[0039] Step S12, setting a communication module in the ink cartridge to realize communication between the ink cartridge and the printer interface circuit, the communication module has a built-in storage unit; the printer interface circuit is connected to the control module and the communication module through a bus;

[0040] Step S13, the printer performs read and write operations on the communication module, and saves the ink cartridge identification information and ink volume information in the storage unit of the communication module. The exchanged data is encrypted and decrypted;

[0041] Step S14, the control module determines whether to reset the byte corresponding to the ink volume of the ink cartridge in the communication module by judging the identification bit o...

Abstract

The invention provides a system for controlling ink quantity reset of an ink box and an ink quantity reset method. The ink box comprises a control module with a built-in storage unit and a communication module with a built-in storage unit; a printer performs read-write operation on the communication module, and stores ink box identification information and ink quantity information in the storage unit of the communication module; and the communication module comprises a data encryption / decryption module, and encrypts / decrypts the data exchanged by the printer and the communication module. In the ink quantity reset method, the control module determines whether to reset according to the identification bit; when the reset is needed, the control module acquires a bus control right, blocks the communication between the printer and the communication module through a resistor, and resets the data of bytes of the ink quantity of the corresponding ink box in the communication module; and when the printer rereads the ink box information, because the data of the ink quantity of the corresponding ink box are reset, personal computer (PC) monitoring software displays that the ink quantity of the corresponding ink box is already fully filled. The method improves the use efficiency of printer consumables, and reduces the environmental pollution.

Description

technical field [0001] The invention relates to a system for controlling ink volume reset of an ink cartridge and an ink volume reset method, in particular to a system and an ink volume reset method for controlling the ink volume reset of an ink box with data encryption and decryption functions. Background technique [0002] At present, the market mainly solves the consumables problem of EPSON 9 contact inkjet printers in the form of discrete ink cartridges, but a prominent disadvantage of discrete ink cartridges is that they are expensive and not suitable for large-volume printing tasks. In addition, discrete ink cartridges The ink cartridge control chip on the cartridge usually uses an ASIC chip (Application Specific Integrated Circuits, that is, an application-specific integrated circuit, which refers to an integrated circuit designed and manufactured in response to specific user requirements and the needs of a specific electronic system), and these circuits are all dispos...
