Storing device and consumable container

Abstract

The invention discloses a storing device, which comprises an interface unit, a storage cell, a detection unit and a control unit, wherein the storage cell is used for storing an initial recording material surplus, a total recording material surplus, and an erasable recording material surplus and / or recording material consumption; the detection unit is used for detecting signals of the interface unit; the control unit controls to update the total recording material surplus stored in the storage cell and rewrite the erasable recording material surplus or the erasable recording material consumption into a calculated value when the detection unit detects preset trigger conditions and the total recording material surplus is greater than a recording material capacity; and when the total recording material surplus is less than or equal to the recording material capacity, the control unit does not actively update the recording material surplus or the recording material consumption stored in the storage cell. The invention provides a consumable container to well manage data in the storing device.

Description

technical field [0001] The invention relates to the field of consumable equipment, in particular to a storage device and a consumable container containing the storage device. Background technique [0002] Printing devices such as copiers, inkjet printers, laser printers, etc. are common office equipment. Consumable containers of the printing device are, for example, ink cartridges, toner cartridges, etc. The consumables of the printing device are mainly ink or toner for recording images. In order to manage the consumable material container, a storage device is often provided on the consumable material container, which provides data for controlling the matching between the consumable material container and the printing device and for subsequent printing. In the storage device, store data about the consumable container: the initial data of the consumable container such as the model of the consumable container, the color of the filled recording material, and the capacity value...

AI Technical Summary

Problems solved by technology

In this way, when the printing device detects that the storage device can still be used to print 20 pages, the recording materials in the consumable container have been consumed and cannot continue to be used for printing.

The more serious situation is that the storage device does not perform a reset operation when the reset threshold is exceeded.

In this way, it is easy to cause unnecessary trade disputes due to large errors in the recording material capacity of the consumables container sold and the storage device installed.
