Inkjet cartridge group and method for detecting installed inkjet cartridge group

Abstract

The invention aims to provide an inkjet cartridge group and a method for detecting an installed inkjet cartridge group. The inkjet cartridge group is detachably installed on an inkjet printer and comprises a plurality of inkjet cartridges; the inkjet printer is communicated with the inkjet cartridges through equipment electric contacts which are arranged, and an optical receiver is arranged on the inkjet printer; a container electric contact, an information-storing device, a light-emitting part and a control part are arranged on each inkjet cartridge; and each control part controls the light of the light-emitting part when receiving the information which is sent out from the inkjet printer to control the light of any light-emitting part. According to the method for detecting the installed inkjet cartridge group, when a certain inkjet cartridge is detected, all the light-emitting parts send out lights. After the inkjet cartridge group and the method for detecting the installed inkjet cartridge group, the detection stability of the installed inkjet cartridges of the printer can be ensured completely, so that the phenomenon that installed inkjet cartridge detection error is caused by the manufacturing error of the light-emitting parts is avoided.

Description

technical field [0001] The invention relates to the field of inkjet technology of an inkjet recording device, in particular to an inkjet cartridge set detachably installed on a color inkjet recording device and a method for detecting the installation thereof. Background technique [0002] A color inkjet printer is equipped with a group of ink cartridges according to needs, and various inks of different colors are packed into different ink cartridges, and all the ink cartridges are installed on the printer. In order to ensure the normal printing of the inkjet printer and prevent printing deviation due to the ink cartridge being installed in the wrong position, it is usually necessary to detect whether the ink cartridge is correctly installed in the proper position of the inkjet printer when the ink cartridge is installed. figure 1 It is a schematic diagram of the detection principle of ink cartridge installation in the prior art, such as figure 1 As shown, it is assumed that...

AI Technical Summary

Problems solved by technology

[0004] However, in the actual detection process, it often occurs that although the ink cartridge is loaded in the correct position, it is judged that it is not installed in the correct or appropriate position because the light receiver does not receive enough light. , the root cause of the above problems is that in the actual production process, due to unavoidable manufacturing errors, the amount of light emitted by each LED lamp will be different, so when the amount of light emitted by the LED lamp of the detected ink cartridge is small, due to The emitted light is scattered light, and the amount of light reaching the light-receiving part does not reach the threshold, so the light-receiving part judges that the ink cartridge is not installed even though the ink cartridge is correctly installed.
