3.2.3.2 Paper registration
After the paper top position is detected by the regist actuator front, the paper, separated into
individual sheets by the separation roller, is fed further for a specified time, and the paper top
position reaches the regist roller so that the paper skew is adjusted. Then, the register solenoid is
turned off, the paper feed roller starts turning, and the paper is fed to the transfer roller in the
drum/toner ASSY.

The regist actuator rear in the path from the regist roller to the transfer roller controls the first print
position on the paper. The machine starts transferring an image when a definite time passes after
the paper is passed through the regist actuator rear.
