CHAPTER 5 TROUBLESHOOTING
b) Sensors of the main body
When a sensor on the main body is in a state
of detection, the mark corresponding to the
sensor will illuminate. Fig. 5-308 shows the
case in which the document tray HP sensor
and the document sensor is are in a state of
detection. The mark '1', which corresponds to
the document tray HP sensor, will illuminate if
the document tray is lowered, and will turn off
when it starts to rise.

Note: When something is wrong with the
operation of the pick-up sensor, the sensor
position is thought to be incorrect. This
problem occurs quite often, especially
when disassembling or reassembling the
pick-up sensor. For the adjustment, refer
to the "VIII. AFTER REPLACING PARTS".
c) Endorser
As with the sensors on the main body, when
the endorser button LED is pressed, or the
sensor of the endorser is in a state of
detection, the mark corresponding to the
sensor will illuminate.
