Serial number switching control circuit and working method thereof, consumable chip and working method thereof, consumable container and printing equipment

Abstract

The invention provides a serial number switching control circuit, a working method of the serial number switching control circuit, a consumable chip, a working method of the consumable chip, a consumable container and printing equipment. The serial number switching control circuit comprises a main control circuit, a diode circuit group, a power supply end, a detection resistor and a voltage detection circuit; the diode circuit group is electrically connected with the power supply end through the detection resistor, and the voltage detection circuit obtains the detection voltage of the detection resistor and sends a voltage feedback signal to the main control circuit; the diode circuit group comprises multiple paths of diode circuits which are connected in parallel; a plurality of serial numbers are stored in the main control circuit, and one serial number corresponds to one diode circuit. According to the serial number switching control circuit, the occupied storage space can be reduced, and the serial number identification stability is improved.

Description

technical field [0001] The present invention relates to the technical field of printers, in particular to a serial number switching control circuit, a working method of the serial number switching control circuit, a consumable material chip using the serial number switching control circuit, and the consumable material chip. The working method also relates to a consumable material container using the consumable material chip, and also relates to a printing device using the consumable material container. Background technique [0002] As a common office equipment, printers provide great convenience for modern office. Existing printers are divided into inkjet printers and laser printers. Inkjet printers use ink cartridges containing ink as consumable containers to spray ink on paper to form text or patterns that need to be printed on paper; laser printers use ink cartridges containing toner The toner cartridge is used as a consumable container to form text or patterns that need...

Problems solved by technology

However, since the printer will record the serial number of the consumable chip that has been used, and the number of compatible chip serial numbers is limited, there is a risk that the serial number of the compatible chip has been stored by the printer, and the new consumable chip will not be recognized. Moreover, currently When the serial number is switched on the market, the serial number conflict identifier is mainly placed in the memory to avoid the next reading of the conflicting serial number, but this will consume storage space, and the identifier still has the risk of failure to read
