2.2.7 Wiping Mechanism
The
wiping
mechanism cleans the surface of the
printhead
nose when the printer is in the ink
system sequence. The wiper drive gear transmits @wer from the paper feed motor via the clutch
gear. When the wiper is raised up (against the
printhead
surt%ce),
the hook for securing the
carriage to the home position is raised, too. When the wiper goes down toward the bottom frame,
the hook goes down, too. Both the black head and the color head are cleaned by this wiper.
