INKJET CARTRIDGE, CARTRIDGE SET, AND CARTRIDGE SET INSTALLATION DETECTION METHOD

摘要

The present invention relates to an ink cartridge, an ink cartridge assembly and a method for detecting the installation of the ink cartridge. A plurality of ink cartridges are detachably mounted on an inkjet printer including a light receiver for receiving light and a plurality of apparatus electrical contacts which are commonly connected with a line, and the ink cartridge comprises a container electrical contact electrically connected with corresponding apparatus electrical contact an information storage device configured to at least store relevant information of the ink cartridge, a light-emitting portion configured to emit light towards the light receiver, and a control portion configured to control the light-emitting portion to emit light according to an emission instruction send by the inkjet printer for controlling the light-emitting portion to emit light, wherein, the control portion of the ink cartridge controls the light-emitting portion to emit light when receiving an emission instruction sent by the inkjet printer for controlling any light-emitting portion of the plurality of ink cartridges to emit light. Therefore, the stability of the ink cartridge installation detection of the printer can be fully guaranteed and the phenomenon of installation detection error caused by the manufacturing error of the light-emitting portion of the ink cartridge can be avoided.
