Abstract
An inkjet printer with multiple printheads in a carriage divides service station functions between a first service station and a second service station. In a preferred embodiment, a black ink printhead is carried by the carriage to a stop position in the first service station where a wiper dedicated to the black ink printhead moves across a stationary nozzle array in a first wiping procedure, and color ink printheads are carried by the carriage to a second service station to move a nozzle array across stationary wipers respectively dedicated to each color ink printhead. The first service station provides spittoon services to all printheads, and the second service station provides capping as well as priming services to all printheads.
