Abstract
A cartridge unit for an inkjet printer is provided which has a body portion having ink storage compartments, a pagewidth printhead configured to receive ink from the compartments and distribute the ink to nozzles arranged in use to deliver the ink onto passing print media, and a capping assembly for capping the printhead. The capping assembly has a body configured to extend the length of the printhead, a capping element housed within the body and movable with respect thereto between first and second positions. The first position is where a portion of the capping element extends from the body and the second position is where the capping element is contained within the body. The capping element is biased into the first position. The ink storage compartments comprise absorption material which stores the ink therein under capillary action for supply to the nozzles of the printhead.
