Abstract
The invention relates to a cartridge for ink-jet printer, comprising a cartridge body, a protective cover moving relatively to the cartridge body under pressure and a detection mechanism for cartridge and remaining ink volume, wherein the detection mechanism for cartridge and remaining ink volume includes the first and second detecting members respectively matching to the first and second sensors on the printer as well as a soft support cap set on the cartridge body and communicating to the ink storage chamber, of which the said second detecting member includes a movable lever, a fixed shaft set on the cartridge body, and a position adjustment member for the movable lever set on the protective cover. The said movable lever is connected with the rotating shaft of the cartridge body through the fixed shaft. It not only meets the detection requirement for cartridge and remaining ink volume, but also removes the movable lever in the ink storage chamber, greatly simplifying production processes and promoting identification accuracy.
