2.2.3 Paper registration
After the paper top position is detected by the regist front actuator, the paper, separated into
individual sheets by the separation roller, is fed further for a specified time, and the paper top
position reaches the paper feed roller so that the paper skew is adjusted. Then, the F/R
solenoid is turned off, the paper feed roller starts turning, and the paper is fed to the transfer
roller in the drum/toner ASSY.
Fig. 3-30
The regist rear actuator in the path from the feed roller to the transfer roller controls the first
print position on the paper. The printer starts transferring an image when a definite time
passes after the paper is passed through the regist rear actuator.
