Operating Principles Wiping/CR Lock Mechanism

The wiping mechanism removes the ink and dust adhered around the nozzles. This is operated during a
cleaning sequence. When the PF motor rotates backward, the torque sent via the head cleaner (wiper)
drive gear and the clutch moves the head cleaner to the path of the printhead. Then the CR unit moves
right and left to wipe the nozzle surface against the head cleaner. The head cleaner leaves the path with
the forward rotation of the PF motor. Only one cleaner head is used for both black and color heads. The
head cleaner is substituted for the CR lock mechanism. When the printer power is off, it locks the CR
unit off the printing side. The right frame also locks the CR at the right end. With this mechanism, the CR
remains in the capping position while transported.
