ABSTRACT:
A service station for an inkjet printing mechanism has a moveable platform that receives waste ink which is occasionally discharged from an inkjet printhead. The printing mechanism has a drive mechanism which moves the platform between a first position for receiving the purged ink, and a second position for discharging the purged ink. The moveable platform may be configured as a rotating annular wheel, with a scraper positioned adjacent thereto for removing the discharged ink from the wheel. The platform may be provided by an endless belt conveyed over two or more rollers. At least one of the rollers may be located substantially under the printhead, and another roller may be located either near or remote from the printhead. Ink may be discharged from the belt using a scraper, and/or using specially contoured rollers. A method is also provided for cleaning an inkjet pen mounted for use in an inkjet printing mechanism.
