A synchronized wiper (12) and pen (16) motion solution for ink-jet printers is described. The invented method and apparatus synchronize the motion of the pen (16) and wiper (12) throughout the wipe stroke, and provide for controlled, simultaneous movement therebetween that avoids pole vaulting, excess interference and ink flicking. Such is accomplished by moving the carriage (14') to a defined position shy of a wiping position above the service station including a sled (10') mounting the wiper (12); raising the sled (10') to produce a proper interference fit between the wiper (12) and the pen (16) while simultaneously moving the carriage (14') at low speed (SLOW); continuing the wipe stroke by high-speed carriage (14') movement (FAST) with the sled (10') stationary; and, at the end of the stroke, lowering the sled (10') to clear the wiper (12) from contact with the pen (16) before reversing carriage (14') motion. The solution lends itself to single- or plural-pen ink-jet printers. <IMAGE> <IMAGE> |
