An inkjet cartridge. The inkjet cartridge includes a body and a seal member. The body includes a first chamber, a second chamber, a third chamber, a first exit, a second exit, a third exit, an opening, and a channel. Ink is received in the first chamber, the second chamber, and the third chamber. The second and third chambers communicate with the second and third exits so that the ink in the second and third chambers flows directly to the second and third exits. The channel communicates the first chamber and the first exit so that the ink in the first chamber flows to the first exit via the channel. The seal member is disposed on the channel via the opening, and seals the channel to prevent ink in the first chamber flowing through the first exit from flowing out of the opening.

Inkjet cartridge

An inkjet apparatus and a method of preventing misplacing the inkjet cartridge therein are disclosed. The inkjet apparatus comprises a carriage, a control unit and a sensor. The carriage is equipped with at least an inkjet cartridge that has an identifiable area. The color of the identifiable area is associated with the colors of ink stored in the inkjet cartridge. The sensor detects the color of the identifiable area and sends a signal to the control unit. The control unit receives the signal and determines whether the inkjet cartridge is correctly placed. If the inkjet cartridge is misplaced, a warning signal is generated to alert the user.
