Tray Lift Errors - Ricoh D025 Service Manual

2.6.4 TRAY LIFT ERRORS

Tray Lift Motor Error
If the tray becomes overloaded and the paper pushes and raises the push-bar [1], this will
switch ON the upper limit switch [2] (a push-switch). Activating this switch switches off the
tray lift motor. This is a backup device that will switch off the tray lift motor if the tray full
sensor or paper height sensors fail.
The table below shows how the state of the two sensors and one switch signal an error.
