Tray Paper Feed Drive - Ricoh MP 7503SP Field Service Manual

• Paper Size Detection. Side fences set against the side of the stack detect paper size. A new paper
length sensor detects paper length as it feeds.
Paper Registration and Transport
• Registration and Transport Mechanism. Paper from each of four paper feed stations (paper banks,
bypass feed tray, duplex unit, LCIT) is guided to the same paper registration unit. In order to make
it easier to remove paper jams, jammed sheets can be removed from the area between the
registration rollers and the entrance to the duplex unit.
• Paper Dust Collection. A mylar sheet extends below the registration roller to collect paper dust.
• Paper Transport Drive Layout. Each PFU is equipped with its own paper feed motor (DC motor).

Tray Paper Feed Drive

Paper Feed From Tray 1
• There are two paper feed motors in Tray 1 (tandem tray).
• In Tray 1 and Tray 2, both motors work together when feeding from either tray.
• This change was implemented to provide more drive power during paper feed.
