Abstract
Print cartridges on printers using stationary print cartridges are accessed by service station components such as wipers, scrapers, cleaning fluid applicators, ink receiving receptacles and cappers in a manner similar to what is done in a conventional scanning printhead printing system. A print cartridge support structure holds one or more print cartridges in a stationary position while applying ink on a media. A printhead is located on each of the print cartridges. The printhead has nozzles for ejecting ink which are arranged in a nozzle array of one or more columns of nozzles. A media movement mechanism provides movement of the media though a print zone located beneath the nozzle array. A printhead servicing station is located outside of the print zone and has one or more servicing modules dedicated for interaction with one of the nozzle arrays when the one of the nozzle arrays is positioned in aligned proximity with its dedicated servicing module. A motorized device coupled to the print cartridge support structure moves the print cartridge support structure out of the print zone to the service station during a period when the print cartridges are not applying ink to the media.
