General chip of printing consumables

Abstract

The invention discloses a general chip of printing consumables. The general chip comprises a substrate which is provided with contacts and an integrated circuit module, and contacts are electrically connected with the integrated circuit module. The integrated circuit module comprises a conversion unit, a data collection unit, a storage unit and a control unit; the conversion unit receives and converts an electric signal from a printer so that the general chip can pass authentication detection of the printer and make response to control of the printer; the data collection unit collects balance data of the printing consumables; the storage unit stores type and balance data of the printing consumables; and when the balance of the printing consumables is insufficient, the control unit sends a signal to the printer so that a printhead of the printer stops running. The general chip disclosed by the invention can be used to solve the problem that a chip of the printing consumables in the prior art is not general and causes high cost.

Description

technical field [0001] The invention relates to the technical field of printing, in particular to a universal chip for printing consumables. Background technique [0002] The chip is a storage device, a memory device, and a device for recording consumption. Before there was no chip, the end of ink was usually detected visually, and if the "end of ink" signal was not reported in advance, it might cause half of the printing, exhaustion of consumables and loss of real-time information. The role of the chip is to prevent the print head from running without ink or toner, and to protect the print head. In order to prevent sudden ink end during printing, Lexmark started using chips in 1998, HP started using chips in 2001, and more than 50 printers used chips in 2005-2006, and then developed to almost all printers. Chips, a group of printing-specific chip companies has formed around the world, and a number of chip factories for consumables have emerged as the times require. [00...
