Punch Sensor
During printing the punch sensor can beco-
me contaminated with lint. Large amounts
of dirt can lead to problems with perforation
recognition.
To free the punch sensor from dust and ab-
raded particles:
1. Remove the cover (1) gently and swivel
downwards (Fig. 1).
2. Remove the sensor arm (2) (Fig. 2).
3. Clean the opening (3) with compressed
air.
The transmission sensor is situated in
the upper and the lower part of the sensor
arm on a level with the indicator (4). You
can find the reflex sensor about 5 mm fur-
ther out in the lower part.
CAUTION! - The sensor surface is
very sensitive to scratches!
Do not use sharp objects or sol-
vents when cleaning the sensors.
