Embodiment Construction

[0010] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0011] see figure 1 , is a schematic diagram of the circuit structure of the printer of the present invention. The printer 10 includes a main control circuit 12 disposed in the printer body and an ink cartridge circuit 14 disposed in the ink cartridge. The main control circuit 12 cooperates with the ink cartridge circuit 14 to realize the data communication between the main body of the printer and the ink cartridge.

[0012] Data communication is performed between the main control circuit 12 and the ink cartridge circuit 14 through a sensor detection line 16 and a signal bus 18 . The signal bus 18 is composed of a reset (RST) signal line, a bidirectional data (DATA) signal line, a synchronous clock (SCL) signal line, a power supply (VDD) line and a ground (GND) ...

Abstract

The present invention relates to an ink cartridge circuit and a printer using the ink cartridge circuit. The ink cartridge circuit comprises a programmable communication circuit. The data communication between the ink cartridge circuit and a printer main body is realized by the programmable communication circuit. The cost and the time spent on the research and development of the ink cartridge circuit adopting upgrading software are largely reduced than those of the ink cartridge circuit needing change specific integrated circuits, so the ink cartridge and the printer, using the ink cartridge circuit, are more adaptable to market changes.

Description

technical field [0001] The invention relates to an ink box circuit and a printer using the ink box circuit. Background technique [0002] Printer is a kind of common office equipment, which provides great help and convenience for modern office. Most of the existing inkjet printers use detachable ink cartridges, which are installed on the main body of the printer, and the consumables are delivered to the recording medium. An ASIC (Application Specific Integrated Circuits, ASIC) for data communication with the main body of the printer is arranged on the ink cartridge. [0003] ASIC is the product of the close combination of integrated circuit technology and specific user's complete machine or system technology. It is characterized by the needs of specific users, that is, the corresponding communication protocol is designed according to specific user requirements and specific electronic system needs. As the market specifications of the main body of the printer continue to cha...
