No. Component Function
sensor signals an error when it detects (1) paper has failed to
leave the paper exit (lag error), (2) detects paper has failed to
arrive at the paper exit (late error), (3) detects paper is in the exit
slot when the machine is turned on.
S7 Exit Guide Plate HP Sensor
Controls the vertical movement of the control exit guide . The guide
plate is in the home position when the guide plate is down and
the actuator interrupts the sensor gap.
S8
Upper Tray Paper Height
Sensor (Staple Mode)
This is the upper sensor of the upper/lower paper height sensor
pair that controls the lift of the upper tray. This sensor detects the
paper height of the stack in the upper tray when the copier is
operating in the staple mode.
S9
Upper Tray Paper Height
Sensor (Non-Staple
Mode)
This is the lower sensor of the upper/lower paper height sensor
pair that controls the lift of the upper tray. When the machine is
switched on, the upper tray rises until the actuator on the tray
triggers this sensor to switch off the upper tray lift motor.
S10 Proof Tray Exit Sensor
This sensor detects and times the feeding of paper to the proof
tray. It also detects whether paper is present at the proof tray exit
when the copier is switched on.
S11 Proof Tray Full Sensor
The top of the stack in the proof tray increases until it nudges the
feeler of this sensor. The sensor then signals that the proof tray is
full and the job halts until some paper is removed from the proof
tray.
S12 Upper Tray Limit Sensor
This sensor controls the position of the upper tray 1) during
straight-through feed out, 2) during shift feed out, 3) when the
machine is turned on. The machine obeys the signal of whichever
sensor is actuated first.
An actuator attached to an arm triggers this sensor. The tip of the
same arm depresses the upper tray limit switch If the sensor fails,
the tip of the arm will activate the upper tray limit microswitch
(SW2) and stop the lift of the upper tray.
Note: When the machine is turned on, the upper tray position is
controlled by either this sensor or the upper tray paper height
sensor (S9).
S13 Stacking Roller HP Sensor
Controls the forward and back motion of the stacking roller (a
sponge roller) located at the output slot of the upper tray. The
