Paper Feed and Registration
Roll 1 Pre-Feeding
! Roll feed clutch 1 engages and turns the Roll 1 feed roller.
! The leading edge of the sheet feeds past the RF exit sensor [A].
! Feed stops.
! The roll feed motor pulls back the leading edge of the sheet until it is 55 mm below the
cutter. Then it stops. This is the pre-feed position [B] for Roll 1.
Roll 2 Pre-Feeding
! The machine pre-feeds the sheet from Roll 2.
! The roll feed motor pulls back the leading edge of the sheet until it is 60 mm below the
cutter and then stops. This is the pre-feed position [C] for Roll 2.
The two sheets stay at their pre-feed positions for the start of the next copy job. There are
no rollers in this part of the paper path. As a result, when the two rolls are at the pre-feed
positions, one can easily feed, and the other does not move.
