7.Detailed Descriptions
670
DF (IM 550F/600F/600SRF Only)
The original feed section consisting of the parts shown in the figure feeds and conveys the original on
the original tray to the original conveying section by the rotation of the DF forwarding pulley and DF
feed roller. The 2nd side of the conveyed original is scanned when passing the CIS and the 1st side at
the optical section (CIS) in the main unit when passing the DF slit glass. The original already scanned is
ejected to the original exit tray by the exit roller.
IM 600F/600SRF only: Double-feed check signals, which are emitted by the DF double feed detector
TX PCB (PCB25) and received by the DF double feed detector RX PCB (PCB26), are used to detect
original double-feeding.
