• The upper limit position is detected by the upper limit sensor, attached to the frame, by means of a shield plate
on the external paper feed unit, which is raised by the paper feed tray. (This is based on the upper limit sensor
and shield plate selected by paper setting.)
• The lower limit position is detected by the lower limit sensor by means of a shield plate built into the elevation
mechanism.
• The paper feed tray detects activation and deactivation of the upper limit sensor as paper is transferred and
maintains paper feed pressure as it rises to the specified position.
• If the paper feed tray detects that there is no more paper, it lowers to the lower limit position.
• The paper feed tray can be raised or lowered by means of the paper feed tray elevation switch. However, it can
only be raised when at the lower limit position and when there is paper.
• The paper feed tray stops moving immediately and completely if the lower limit frame on the bottom of the tray is
pressed and the unit detects that the safety switch was activated.
