Process box chip, process box and storage unit switching method for process box chip

Abstract

The invention provides a processing box chip, a processing box and a storage unit switching method of the processing box chip. The processing box chip comprises a substrate, wherein the substrate is provided with a first storage unit, the substrate is also provided with a second storage unit and a control unit, both the first storage unit and the second storage unit are provided with residue data of printing supplies, the control unit is selectively and electrically connected with the first storage unit or the second storage unit, and one, electrically connected with the control unit, of the first storage unit and the second storage unit is communicated with exterior through the control unit. The processing box is provided with the processing box chip. The invention also relates to a method for switching the storage units of the processing box chip. Due to the adoption of the processing box chip, the processing box and the storage unit switching method, the service life of the processing box is effectively prolonged, the unnecessary waste can be avoided, and the environmental pollution can be alleviated.

Description

technical field [0001] The invention relates to the field of printing consumables, in particular to a processing box chip capable of switching storage units, a processing box installed with the chip and a method for switching the storage unit of the chip. Background technique [0002] Printers and copiers are widely used imaging devices. Existing printers or copiers generally use toner or ink as imaging consumables, and the consumables used for imaging are contained in corresponding boxes, such as process cartridges or ink cartridges. These containers are usually called Consumable container. Most of the consumable container boxes are equipped with consumable chips. When the consumable container is installed in an imaging device such as a printer or copier, the consumable chip can exchange information with the printer or copier. Taking the process cartridge as an example, the process cartridge chip generally stores invariable data such as production date, manufacturer, devic...

AI Technical Summary

Problems solved by technology

[0004] However, once the consumables in the process cartridge are depleted, the storage unit of the process cartridge chip will also be written with "depleted" data, and the printer will no longer use the process cartridge for printing operations, even if the process cartridge or refilled carbon powder, the printer will still not print according to the "depleted" information recorded in the chip, so ordinary users have to replace the process cartridge and the chip together, or recycle the process cartridge and discard the old process cartridge chip and buy New processing cartridge chips, which cause waste and damage to the environment
