2.6 PAPER FEED
2.6.1 OVERALL
The top sheet of the paper on the paper table is first fed by the pick-up roller [A].
Then, it is separated by the paper feed roller [B] and the friction pad [C], and
transported to the registration rollers [D]. The upper and lower registration rollers
transport the sheet to the drum.
The paper feed roller is driven by the main motor, and an independent stepper
motor is used to control the registration roller. The registration roller synchronizes
the paper feed timing with the master on the drum. The registration roller starts
rotating after the paper has come into contact with the rollers and has been
aligned.
