Shift Tray Lower Limit Detection; Shift Tray Side-To-Side Movement - Ricoh SR4080 Field Service Manual

Shift Tray Lower Limit Detection

• This machine has two shift tray lower limit sensors: shift lower limit sensor [A] (S9) for large paper
(B4 and larger) and shift lower limit sensor [B] (S11) for small paper (smaller than B4). (Sensor [C]
(S10) is not used.)
• When the actuator [D] enters sensor [A] while using large paper (about 1500 sheets are on the
tray), a message will be displayed and copying will stop.
• When the actuator [D] enters sensor [B] while using small paper (about 3,000 sheets are on the
tray), a message will be displayed and copying will stop.

Shift Tray Side-to-Side Movement

In sort/stack mode, the shift tray [A] moves from side to side to separate the sets of copies.
• The horizontal position of the shift tray is controlled by the shift motor [B] and shift gear disk [C].
• After one set of copies is made and delivered to the shift tray, the shift motor turns on, driving the
shift gear disk and the shaft [D].
• The end fence [E] is positioned by the shaft, creating the side-to-side movement.
• When the shift gear disk has rotated 180 degrees (when the shift tray is fully shifted across), the
cut-out in the shift gear disk turns on the shift tray half-turn sensor [F] and the shift motor stops.
