Tray Movement Mechanism
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-Sta-
ple 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].
