At the 1st stage, the controller drives the main motor without energizing the solenoid so that the
paper feed roller simply idles.
At the 2nd stage, the controller energizes the solenoid so that the paper feed roller no longer
rotates and the paper pick-up roller starts rotating to pick up paper into the machine, a sheet at a
time. After the leading edge of the pulled-in paper passes through the manual insertion sensor
actuator, the paper is further fed for the specified time length. Accordingly, the leading edge will
reach the paper feed roller where the paper skew will be eliminated.
At the 3rd stage, the controller deenergizes the solenoid to rotate the paper feed roller for feeding
paper to the transfer block in the drum unit.
When the leading and trailing edges of the paper pass through the registration sensor actuator, the
sensor signals them to the controller. According to those signals, the controller may determine the
first print position on the paper.
