2.2 PAPER FEED
2.2.1 PAPER FEED MECHANISM
This machine uses the FRR paper feed system (paper feed roller [E], separation roller [H], pick-up roller [G]).
When the right door is closed, the tray lift motor raises the tray to the position where the top of the paper stack in the tray interrupts the tray lift sensor [D]. The paper feed motor switches on, then the pick-up solenoid [C] switches off and the pick-up roller drops onto the top of the stack of paper. The paper feed clutch transfers drive to the paper feed roller [E], pick-up roller [G] and separation roller [H].
The rotating pick-up roller lowers and feeds the first sheet when it contacts the top of the stack. The separation roller [H], in contact with the feed roller, only allows one sheet out of the tray.
As soon as the paper feed sensor [F] detects the leading edge of the paper, it switches off the pick-up solenoid which raises the pick-up roller. The feed roller feeds the sheet to the registration roller in the main machine through the relay roller [B].
This process is repeated for each sheet.
The paper feed sensor [F] detects "JAM7" and the relay sensor [A] detects "JAM58".
