e) Printhead maintenance unit
The printer performs the printhead cleaning operation at the home position of the carriage.
The purge motor is used for wiping. When the carriage is stationary at the home position, the printhead installed
in the carriage is wiped with the wiper blade. The wiper blade is pressed against the absorbent material soaked
with glycerin so that the wiper blade is moistened with glycerin, thus improving the wiping performance.
Idle ejection of ink is performed on the cap, the borderless ink tray of the platen, and paper.
The suction operation is performed by rotating the pump motor after completion of capping. (Note that the
