Maintenance Unit
 The maintenance unit, mounted on the right side of the machine, cleans the print
heads.
 Maintenance motor: Raises the suction cap that cleans the print heads and caps the
K1 print head, raises the rubber scraper, moves the wipers, and drives the suction
pump.
 Maintenance lift motor: Raises the print head cap for K2, C, M, and Y that protects
the print heads from drying out, and slides the cleaning unit (which includes the
suction cap) forward and backward.
