Abstract

The invention belongs to the field of ink-jet printing and particularly relates to a printer chip, an ink box and a storage allocation method for the printer chip. According to the technical scheme, the printer chip comprises a chip control circuit, a data storage unit for storing data, and a communication unit for being communicated with a printer; the storage unit and the communication unit are electrically connected with the chip control circuit; and the data storage unit comprises authorization flag bits, and the data storage unit is arranged in a non-authorized state and an authorized state through the authorization flag bits according to different numerical values. The authorization flag bits and authorization verification matched with the authorization flag bits are additionally arranged, chip data can be covered, read and written again and used normally on the basis of guaranteeing data stability and reliability, and the service life of the printer chip is prolonged.

Description

technical field [0001] The invention belongs to the field of inkjet printing, and specifically relates to a printer chip, an ink box, and a method for storing and distributing the printer chip. Background technique [0002] With the popularization of office automation, printing equipment has become an indispensable equipment in office activities. Common printing equipment includes laser printing and inkjet printing, and inkjet printing includes inkjet printers and ink cartridges installed in the printers. [0003] During the use of inkjet printers, consumables, such as ink cartridges, need to be replaced regularly. When the ink in the ink cartridge is exhausted, the ink cartridge needs to be replaced. Replaceable devices such as ink cartridges contain printing parameters. These printing parameters are often stored in chips. This kind of printer chip is installed in replaceable devices such as ink cartridges, so that the device can be used every time. After the first replace...
