2.4 TRAY MOVEMENT MECHANISM
2.4.1 UPPER TRAY
[A]: Upper Tray Lift Motor
[B]: Upper Feeler
[C]: Upper Tray Paper Height Sensor 1
(Staple Mode)
[D]: Upper Tray Paper Height Sensor 2
(Non-Staple Mode)
[E]: Lower Feeler
[F]: Upper Tray Limit Sensor
[G]: Upper Tray Limit Switch
[H]: Upper Tray Full Sensors
The B804 (shown above) has only one upper tray full sensor (the higher sensor at [H]).
The B805 has two upper tray full sensors (the upper and lower sensor at [H]). On the
B805 the upper sensor detects tray full for heavier paper (A3, DLT, B4, LG, 12 x 18”), and
the lower sensor detects tray full for lighter paper (A4, LT, etc.).
The tray full capacity is 2,000 sheets (B804) for A4, LT and 3,000 sheets (B805) for A4,
LT.
Five sensors and one switch control the operation of the upper tray lift motor [A].
