Cleaning of the Card Sensor
Because of electrostatic charging, dust depositions on electronic devices are
possible in the course of time. The reason might be paper abrasion as a
consequence of card insertion or the place of installation itself. The card sensor is
one of the parts concerned.
Problem:
The card is not inserted because the card sensor does not recognize it,
or the card is inserted but not read correctly and is therefore
immediately ejected.
Reason:
Card sensor is dirty (Pollution, paper abrasion, etc).
Remedy:
Clean the card sensor by means of compressed air.
See the procedure described below. Use a compressed-air spray with a
pressure of max. 4,1 bar.
Attention!
Please use only a standard pure spray without additives.
Maximum pressure 4,1 bar at 20° C.
Do not use compressed-air pistols. An excessive pressure might
damage the time recorder.
Attention!
Do not use pointed, hard or rough surfaced objects. They might
damage the card sensor.
Procedure:
1.
Open the time recorder and remove the front case.
2.
Switch the time recorder off.
3.
Cut off the voltage supply of the external power supply of the PERFECT.
4.
Remove the metal back plate. See chapter 2 "Installation".
If the time recorder is wall-mounted, remove the back case from the metal
back plate.
5.
Place the compressed-air spray bottle with the capillary tube as illustrated
and release some impacts in the card guide slot.
6.
Connect the time recorder and restore the voltage supply of the building.
7.
Before switching on the time recorder, please insert a blank card in order to to
have the reader optics re-adjusted. Please see chapter “Procedure for Sensor
Adjustment”.
