The external paper feed section is comprised of the external paper feed unit and paper feed tray unit (including the
elevation mechanism). Paper loaded in the external paper feed tray is fed to sections inside the printer one sheet at
a time.

1. Paper Feed Tray Unit
• The paper guides can be moved into position to match the width of paper used and then locked with the paper
guide lever.
• The size of paper is detected by output from the paper width potentiometer and paper length detection sensor on
the paper feed tray.
• From the point when paper is loaded in the paper feed tray, a print signal triggers the elevator motor to raise the
paper feed tray so that the top sheet reaches the upper limit position (the feeding position).
