NOTE: 1) The MPU controls the registration roller start timing to synchronize the
print paper with the image on the master on the drum.
2) The motor speed depends on the selected printing speed.
3) By pressing the image position keys on the operation panel, the
registration motor start timing is changed.

6.9.6 PAPER FEED RETRY MECHANISM

When paper is misfed at the paper feed tray, a paper feed jam is not displayed,
and the machine tries to feed the paper again.
The paper registration sensor does not turn on after the paper feed motor turns,
and the drum turns without paper. Then, when the feed start sensor is on again,
the paper feed motor starts to feed again.
The paper feed retry mechanism only operates during printing, and not for the trial
print.
The retry is done only one time. If paper is not fed, then a misfeed occurs.
