Consumable chip and its data resetting method, consumable container

Abstract

The invention provides a consumable chip and its data resetting method, as well as a consumable container. The chip comprises an electronic module and a light-emitting diode. The electronic module is provided with a control unit and a memory, which includes a first storage area and a second storage area. Consumable margin data are stored in the first storage area, and consumable margin predetermined value data are stored in the second storage area. At least one pin of the light-emitting diode is in connection with the electronic module, wherein, the electronic module is also provided with a data resetting unit. The method comprises that: the data resetting unit receives the on-off signal of the light-emitting diode, and judges whether the frequency of the on-off signal is higher or lower than a set value, if so, the resetting unit sends a data resetting signal to the control unit, which, after receiving the data resetting signal, writes the consumable margin predetermined value data stored in the second storage area into the first storage area to cover the consumable margin data. The consumable chip of the invention can ensure that the consumable margin predetermined value data can be written into the first storage area timely and guarantee stable working of the consumable container.

Description

technical field [0001] The invention relates to the field of printing, in particular to a consumable chip mounted on a printing consumable, a data reset method for the chip, and a consumable container equipped with the consumable chip. 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 to be printed on the medium. [0003] see figure 1 , an existing color inkjet printer has a casing 11, figure 1 The inkjet printer is shown with the chassis 11 omitted. The machine core 12 of ink-jet printer is provided with in the casing 11, and is provided with a sl...

Problems solved by technology

Moreover, the other side of the substrate is provided with an electronic module and a light-emitting diode that are electrically connected to the electrical contact 34, and the electronic module is provided with a control unit and a memory, etc. For the same reason, the chip 33 also has a predetermined value of remaining carbon powder. The problem that data cannot be written into the first storage area in time and overwrite the original toner remaining data will affect the work of toner cartridges and laser printers

[0015] In addition, toner cartridges or toner cartridges can be detachably installed on most existing imaging equipment such as copiers, fax machines, or all-in-one machines as consumable containers. These chips also have the same problem as the chip of the ink cartridge, that is, the data of the predetermined value of the remaining toner cannot cover the original data of the remaining toner in time
