Abstract
A service station for use in servicing one or more inkjet print cartridges includes a service station sled assembly movably attached to a service station chassis. The sled assembly includes at least one wiper and at least one cap. In one embodiment, the service station includes a cam and cam follower that interact to move the sled assembly. The cam is shaped so that movement of the cam to a first position causes each cap to contact a printhead of a corresponding inkjet print cartridge. Movement of the cam to a second position causes the cap to move away from the printhead and moves the wiper into a wiping position. In another embodiment, a service station according to the invention for use with a facsimile machine including inkjet printing apparatus includes a motor that is positioned so as to minimize the footprint of the service station. A method according to the invention includes the steps of positioning a print carriage adjacent to a service station including a sled assembly, and rotating a cam of the service station such that a cam follower of the sled assembly interacts with the cam to cause movement of the sled assembly.
