PURPOSE: To obtain a method and an apparatus for cleaning the orifice plates of multiple printheads of an ink jet printer.
CONSTITUTION: The apparatus includes a multi-blade wiper 60 which is indexed automatically to permit each printhead 31, 33 to be wiped in sequence by a selected blade 61, 63. The desired cleaning is produced by dragging a printedhead across the selected wiper blade 61. The wiper mechanism 140 may also comprise a plurality of resilient blades 154, 156 each having an octagonal shape and rotatable about an axis. A cam 180 coupled to the printhead carriage 114 causes pivoting of the wiper blades 154, 156 into contact with the printheads 131, 133 as well as rotation of the blades to facilitate cleaning thereof. In the inventive method, ink is expelled from the printheads to rehydrate dried ink thereon to facilitate removal thereof.
