Repeat this procedure from 14.3 until the desired result is achieved and then
return to the Run Screen.
With the motors running, operate the Compressor Switch to start the Compressor.
From the Run Screen start the Vacuum Drum & Suction. Hold a Test Sheet over the
drum (do not allow the sheet to be fed) & ensure the drum does not stop. If it stops
check the
on the Single Stepper Driver PCB is set
correctly (Set Switches as shown on the Wiring Diagram on page 85)
Enter the Engineering Tools Section & Select " ".
Alter the setting as required. This setting controls the length of time that the
suction is on for before the drum starts to rotate. Results have shown that the optimum
setting is 03.
The DigiFold is equipped with a total of four Sensors & three Detectors. They all have indicator
LED's on the Main Control Board & their operation can be checked from the Advanced Tools
Menu. The sensitivity of the Sensors can be adjusted individually by adjusting the appropriate
Potentiometer on the Main Control Board using a small insulated electrical screwdriver. The
Detectors have no adjustments.
Check the operation of each Sensor or Detector in turn by entering the Tools Menu &
operate Operate each sensor manually.
The registers the lead edge of the sheet to within 0.1mm. Its correct
setting is extremely critical to the performance of the machine and
15.2 Ensure the Red LED3 on the Main Control Board is Off. Place an 80gsm
sheet on the Loading Table with its Lay Edge against the Fixed Side Lay. Slide the
sheet up to the Input Rollers & rotate the machine by hand to drive the sheet
through the Lead Edge Sensor - the display should read
and LED3
should come on as the sheet passes through the sensor beam.
15.3. Ensure there is no paper in the machine before setting the sensitivity. This is done by
adjusting the Crease Edge pot (VR4), on the Main Control Board. Turn the pot fully
anti-clockwise. Turn the pot clockwise until LED3 is just On, and then back anti-
clockwise 60° (i.e. about 10 clock minutes).

Note.-
If LED3 does not come On, when VR4 is set between the 6 o’clock and 9 o’clock positions the
Lead Edge Sensor should be replaced. (See Below)
