Problems solved by technology

In order to protect the profits of the company, the original printer manufacturer has applied an encryption chip to the printing consumables, and set some special storage areas in the chip. Once the data in the special area overflows, no data can be recorded, and it is prevented from being rewritten by others. Or reset the chip, resulting in consumables that cannot be recycled; at the same time, compatible consumable manufacturers cannot produce cheap general-purpose consumables, and consumers have to spend a high price to buy a new set of original consumables and install them on the printer.
It is recorded that the functions of all parts of the used consumables are normal, and they can continue to be used after regeneration, but the memory chip installed on the old consumables

Abstract

The invention provides a common chip for regenerative printing supplies. A circuit combination of the common chip and an old chip is adopted, a command judgment unit is arranged on a microcontroller of the common chip to judge whether a command sent out by a printer contains a password check command signal, a password check command is stored through the microcontroller and forwarded to the old chip, a check result value is worked out through the old chip and sent to the microcontroller, the common chip then responds to a verification command, and the verification command is sent to the printer; alternatively, the microcontroller controls setting of an on-off control unit, a power supply line or a data bus line of the old chip is controlled by the on-off control unit to be switched on or switched off, and the old chip directly receives the password check command and responds to the verification command. Response processing is indirectly or directly verified through the old chip, regeneration of old printing supplies is achieved through verification of the printer, the old printing supplies are reused, and low carbon and environmental protection are achieved.

Description

technical field [0001] The invention relates to a circuit, in particular to an integrated circuit used in consumables such as regenerated printer toner cartridges, powder cartridges, ink cartridges, and fixers. Background technique [0002] In the prior art, at present, the use of printers is becoming more and more popular, and the demand for printing consumables is constantly increasing. The printing consumables mainly include ink cartridges, toner cartridges, toner cartridges and fusers. In order to protect the profits of the company, the original printer manufacturer has applied an encryption chip to the printing consumables, and set some special storage areas in the chip. Once the data in the special area overflows, no data can be recorded, and it is prevented from being rewritten by others. Or reset the chip, so that the consumables cannot be recycled; at the same time, compatible consumable manufacturers cannot produce cheap general consumables, consumers have to spend...
