CHAPTER 5 TROUBLESHOOTING
8. Analog
This mode is used to display the analog
values of sensors. It allows you to check the
operation of sensors, such as the ultrasonic
sensor, document guide width sensor, and staple
sensor, which are not included in the main body
sensors of Dcon Check operation window.
a) USS
After selecting ‘Analog’ in the Service
window, a window displaying the analog value of
each sensor appears (See Fig. 5-319). The box
menu of Fig. 5-319 shows ‘USS’, which means
the window displays the analog values related to
the ultrasonic sensor.
Setting papers on the ultrasonic sensor
portion in the feed path, while avoiding the
registration sensors, allows you to check the
operation of the ultrasonic sensor.
When one sheet is set, the “Document
judgement” lamp will illuminate. When two or
more sheets are set, the “Document judgement"
lamp and “Amplitude judgement” lamp will
illuminate, and the “Phase judgement” lamp will
illuminate or flash.
To close the window, press the ‘Close’
button.
Opening the box menu will allows you to
choose 'Feeder 1’ or 'Feeder 2’, in addition to
‘USS’ (See Fig. 5-320).
