Feed Station Overview
The machine can feed paper from the manual feed table or the optional roll feeder. With all
options installed, there are four paper feed sources:
!
Manual Feed Table (bypass tray)
! Roll 1: Front roll in the Roll Feeder (Roll Feeder B851 has the front roll only)
! Roll 2: Rear roll in the Roll Feeder (Roll Feeder B852 has the front and rear rolls).
! Paper Cassette (installed in the bottom of the Roll Feeder)
The user sets one of these paper feed sources at the operation panel.
When the machine detects the original, the feed motor and the registration motor start, and
paper feed starts. The paper goes into the machine from the paper supply source, goes
through the RF exit rollers, and then to the registration rollers.
The registration rollers stop temporarily for paper skew correction, and then start again to
feed the paper to the drum.
