11.8 How to position the paper sensor guide bar
The paper sensor guide bar of the Neopost AS-3640 is pre-assembled. If the position of
paper sensor guide bar has to be shifted due to modifications or repairs, the default settings
have to be restored.
Sensor type “DK12 (No Reflector)” 4142016Z (K0804.024)
• The paper sensor should have a working distance of 11 ± 2 mm above the media
surface.
• Since the transport belt has holes for the vacuum suction, the paper sensor has to be
placed above an area without holes.
• The recommended and pre-adjusted horizontal distance between the paper sensor
and the first print unit is 90.1 mm / 3.55". If the actual distance between the sensor
and the print unit should differ, use the option , on page 59 to adjust the set value.
The maximum value is 200.9 mm / 7,99".
Horizontal distance between paper sensor and first print unit
Good print results may only be achieved if the distance is measured
exactly and set correctly in the printer options.
• The paper sensor detects the edges of each transported print medium. To ensure
correct operation a "teach-in" of the sensor must be done. This may be necessary
when working with material that has low contrast compared to the transport belt
underneath.
