Wiping/CR Lock Mechanism
The wiping operation removes ink and dust that adhere to the nozzles. This occurs during the cleaning
sequence. When the pump motor rotates backward, torque sent via the head cleaner (wiper) drive gear and
clutch moves the head cleaner to the wiping position. The CR unit moves right and left to wipe the nozzle
surface against the head cleaner. When the wiping is complete, the pump motor rotates forward to move the
head cleaner back. One head cleaner is used for both the black and color printheads. The head cleaner also
functions as a CR lock mechanism. When printer power is off, it keeps the CR unit from shifting left (to the
printing side). The switch lever locks the CR at the right end by connecting it to the disengagement
mechanism. The CR unit remains in the capping position when transported.
