2-1-1 Mechanical construction
(1) Original feed mechanism
The DF consists of the components shown in Figure 2-1-1. It conveys the original across the DF contact glass in synchro-
nization with the copier scanning operation.
During primary original feed, the original feed motor (OFM) turns on and the lift cam starts rotating, moving the lift guide up
until the originals make contact with the DF forwarding pulley. The DF forwarding pulley feeds the originals one by one and
the DF original feed pulley conveys the original further into the DF. During secondary original feed, the original conveying
motor (OCM) turns on and the DF upper registration roller and DF lower registration roller convey the original onto the DF
contact glass. The DF upper eject roller and DF lower eject roller then eject the original to the original eject cover.
