7.13.3 PAPER FEED MECHANISM

friction roller [B] comes in contact with the paper feed roller, and the pick-up roller [C] contacts
the top of the paper (to prevent paper remaining, when the paper feed tray is withdrawn, the
pressure release lever returns and contact with the rollers is released).
The machine is in standby mode for paper feeding when the tray bottom plate moves up. When
the paper feed clutch (CL9) turns ON after the paper transport motor (M12) turns ON, the rollers
start to rotate and paper is fed.
The feed guide functions as a paper guide and roller clip ring. The feed guide prevents the
paper from winding up.

sensor (S31) [A] near the paper feed roller adjusts the paper feed timing.
