A removable service module in a printer service station periodically interacts with a print cartridge, and is sized for proper installation in a matching service carriage slot. Upper and lower boundary guides on the service carriage prevent an unmatched or wrongly positioned service module from fitting through a slot entrance and becoming seated into a completed mounting position.

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.

A technique for servicing an inkjet printhead on an inkjet printer including a first service module. The technique includes identifying a printhead-related service condition not adequately addressed by servicing the printer with the first service module, providing a second service module different from the first service module and adapted to address the printhead-related service condition. A set of instructions can be provided for using the second service module with the inkjet printer. The technique can further include removing the first service module from the printer, installing the second service module in the printer, and using the set of instructions, conducting a special printer servicing operation. After completion of the special printer servicing operation, the second service module can be removed from the printer, and the first service module reinstalled in the printer in place of the second service module.

A system for venting gas at ink containers which supply inks to a multi-channel inkjet printhead is provided having a plurality of ink containers for supplying fluids to a printhead having a plurality of ink channels, and a gas vent assembly having a plurality of gas vents. Each ink container has an ink port connected to a corresponding one of the ink channels of the printhead and a gas port. Each gas vent is connected to a corresponding one of the gas ports of the ink containers. The gas vents of the gas vent assembly are in fluid communication with the external atmosphere.
