Pick-Up roller (Tray 1,2,3,4 and MP Tray)

This roller picks up the paper from the tray.

Forward roller (Tray 1,2,3,4 and MP Tray)

This roller is placed against the reverse roller. It transports the paper from the pick up roller to feed roller.

Reverse roller (Tray 1,2,3,4 and MP Tray)

This roller is placed against the forward roller and transports only one sheet to the feed roller. When two sheets of

paper or more are transported from the pick up roller, the load of the torque limiter of the reverse roller is heavier

than the frictional force between the sheets. As a result, the reverse roller is stopped and the lower paper does

not advance any further.

This roller transports the paper sent from the forward/reverse roller to the registration roller.

Registration roller

This roller aligns the leading edge of the paper and transports the paper to the transfer roller Assy.
