Paper registration

Passing of each sheet of paper which is separated by the separation roller is detected by the
registration front actuator. Then, the paper is fed further for a certain time, and its front edge
hits the stopped PF registration roller so that the paper skew is corrected. After such
correction, the registration solenoid is turned OFF, the power of the paper feed motor rotates
the PF registration roller, and the paper is fed to the belt unit. The fed paper is fed to the
delivery unit by the belt unit.
