ABSTRACT:
A maintenance station for maintaining either a monochrome or a multi-color printhead in an ink-jet printer includes a single flexible wiper having a first wiping edge for wiping the ink-jet nozzle surface of a monochrome printhead and a plurality of second wiping edges for wiping the ink-jet nozzle surface of a multi-color printhead. Wiping of a monochrome printhead is accomplished by moving the printhead to one side of the wiper, raising the wiper into the path of travel of the nozzle surface, and moving the printhead past the wiper. Wiping of a multi-color printhead is accomplished in a similar manner but the printhead is first positioned on the opposite side of the wiper. The flexibility of the wiper is chosen to apply an optimum wiping force to a multi-color printhead as the printhead is moved past the wiper. A backstop is provided at one side of the wiper to brace it against deflection, so that the wiper applies a greater wiping force to a monochrome printhead than it does to a multi-color printhead. A microprocessor based controller senses the type of printhead and executes a first or a second maintenance routine depending on the type of printhead that is present in the printer.
