a) Purge driving motor
The purge motor drives the wiper, carriage lock, and pump. It is a constant-voltage motor operating
with a 1-2 phase drive.
b) Wiper
The wiper consists of a wiper and wiper cleaner.
The wiping operation is executed while the carriage is fixed at the purge section. It wipes the print
head's nozzle array in a vertical motion.
c) Cap
The rubber cap protects the print head (capping operation) and sucks out (pumping operation) the ink in
the cap.
When the carriage moves to the capping position, the cap is pressed against the print head's face plate.
There is a different cap for the black and color print heads.
An ink tube connects the rubber cap to the pump and air valve.
