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 which extends the printhead length, a capping element housed within the body and having a rim portion which caps at least a portion of the printhead and a displacement assembly housed within the body for moving the capping element between a first position where the rim portion extends from the body and a second position where the rim portion is contained within the body. The displacement assembly is controlled by an electromagnet which determines the position. The ink storage compartments comprise absorption material which stores the ink under capillary action.
