Embodiment Construction

[0025] like figure 2 As shown, the printer of the present invention includes a printer main control circuit 11 and a character car control circuit 17. The printer main control circuit 11 is arranged in the printer and is the core control part of the printer. The character car control circuit 17 is arranged on the print car. The printing carriage slides back and forth, and the carriage control circuit 17 is also in contact with the consumable chip. The data communication between the consumable chip and the main control circuit 11 of the printer needs to be transmitted through the carriage control circuit 17 .

[0026] The communication circuit between the printer main control circuit 11 and the character car control circuit 17 is provided with a consumable chip monitoring circuit 12 for monitoring the model of the consumable chip and also monitoring the communication data between the consumable chip and the printer. Monitoring consumable chip monitoring circuit 12 includes a s...

Abstract

The invention provides a consumable chip monitoring circuit, a monitoring method thereof, a monitoring circuit board and a printer. The printer is provided with a monitoring circuit board. The monitoring circuit board comprises a consumable chip monitoring circuit. The consumable chip monitoring circuit comprises a micro-control circuit and a signal interference circuit, wherein the micro-control circuit obtains chip information data sent by a carriage unit control circuit to a printer main control circuit, and the micro-control circuit sends a control signal to the signal interference circuit; the signal interference circuit comprises a first path and a second path, and the first path and the second path are electrically connected; the first path receives main control data sent by the printer main control circuit and sends the main control data to the carriage unit control circuit; and the first path receives the chip information data sent by the carriage unit control circuit and sends the chip information data to the printer main control circuit. According to the invention, the printer can be prevented from being damaged by using a non-original consumable chip, and thus the service life of the printer is ensured.

Description

technical field [0001] The invention relates to the field of printers, in particular to a consumable chip monitoring circuit and a monitoring method applied to printers, and also to a circuit board and a printer using the circuit. Background technique [0002] As a common office equipment, printers provide great convenience for modern office. Existing printers are classified into inkjet printers and laser printers. Inkjet printers use an ink cartridge containing ink as a consumable container to spray ink onto paper to form characters or patterns to be printed on the paper. [0003] like figure 1 As shown, some inkjet printers are equipped with a core and a character carriage, and a printer control circuit 1 is arranged in the core, and the printer is also provided with a slide bar, and the character carriage can reciprocate along the slide bar to complete the printing operation. A character car control circuit 2 is provided on the circuit board of the character car. In ord...
