Tray Movement Mechanism
B803/B805/D373/D374/D636/D637 48 SM
Tray Full
B804
When the actuator on the tray activates the upper tray full sensor [H] the tray lift
motor [A] switches off. Operation resumes after some copies are removed from
the tray. Upper Tray Capacity: 2,000 sheets (A4, LT)
B805
The operation of the upper tray full sensor is the same as the B804. Capacity:
1,500 sheets for A3, B4 or other large paper.
An additional upper tray full sensor (below sensor [H]) allows more sheets to
stack on the upper tray. Capacity: 3,000 sheets (A4, LT)
2.4.2 LOWER TRAY (B804 ONLY)
The lower tray sensor actuator arm [A] rests on the top of the stack of stapled booklets as they are
output to the lower tray. A flap depressor [B] keeps the open ends of the booklets down.
The front lower tray full sensor (S34) [C] and rear lower tray full sensor (S33) [D] detect when the
lower tray is full of booklets.
