Ricoh G148, Service Manual

Page: 494 / 537

When the machine detects that the tray is in the machine, the right tray paper sensor [A] (under the tray)
checks whether there is paper in the right tandem tray.
• If sensor [A] was not present and the tray was empty, the bottom plate would have to lift until the 1st
tray lift paper end sensor (at the top of the tray) detected that there was no paper, and this would
waste several seconds.
If paper is detected, the lift mechanism starts:
• 1st tray Lift motor [B]
→
Coupling gear [C]
→
Pin [D] on the lift shaft [E]
→
Wires [F]
→
Slots at the
ends of the tray support rods [G, H]
→
Tray bottom plate [I].
The tray goes up until both of the following occur:
• The paper pushes up the pick-up roller and the lift sensor is activated
• The paper end sensor at the top of the tray is deactivated.
