NOTE
Paper feed motor drive switching
Power from the paper feed motor is switched for separation and feed of the paper, and
nozzle cleaning mechanisms by the direction of paper feed motor rotation, the slide lock
pin on the purge unit and swing gear. When the carriage moves in front of the purge
unit, the carriage pushes the control pin, and releases the swing gear driven by the paper
feed motor. When the paper feed motor rotates in the paper feed direction in this state,
the swing gear rotates and moves up to the auto sheet feeder drive gear to drive the auto
sheet feeder. Alternately, when the paper feed motor rotates in the reverse direction, the
swing gear rotates and moves up to the purge drive gear to drive the purge unit.
When the control pin is locked, the paper feed roller is driven to feed the paper.
