2-1-9 DF section
(1) SDF (15 cpm copier)
The DF consists of the components shown in Figure. It conveys the original across the DF contact glass in
synchronization with the copier scanning operation.
When an original is placed on the original table and the DF original detection switch turns on, the scanner motor (SM)
turns on to drive the DF to feed the original.
When the DF change solenoid (DFCHSOL) turns on, the scanner motor (SM) drive to the scanner is interrupted and the
scanner scans the original from the DF at a fixed position.
The scanned original is ejected onto the original holder by the DF eject roller and DF eject pulley.
