A PROTECTOR FOR A PRINTHEAD CHIP AND A CARTRIDGE USED WITH THE PROTECTOR

摘要

The invention discloses a protector for a printhead chip and a cartridge used with the protector. The protector (1,8) is independent of the cartridge (9) containing ink. A contact surface (3) of the protector facing a printhead contact is provided with contacts (6) contacting with contacts of the printhead chip correspondingly. The contacts (6) are connected with a memory (5) and closed between the contacts of the printhead chip and the protector. The protector does not correlate with the cartridge, especially an ink supply port (11) and an ink supply needle of the cartridge in structure. Therefore, even the cartridge oscillates or moves horizontally and thus offsets from a centerline of the ink supply port, communicating effect will not be influenced.
