Wiping/Cr Lock Mechanism - Epson Stylus Color 1520 Service Manual

Operating Principles

2.2.7.1 Wiping/CR Lock Mechanism

The wiping mechanism removes ink and dust that collect around the nozzles during the cleaning sequence.
When the PF motor rotates backward, 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 forward rotation of the PF motor causes the head cleaner to
leave the path. Only one head cleaner is used for both black and color printheads. The head cleaner is used
as 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. The CR remains in the capping position while transported.
