3.1.2 Camera Faults
The service program is used to determine whether a camera is faulty. The program can display the
camera status. If the camera status is shown as OK it is possible that the camera sends wrong data or no
data at all. This fact would be shown by an unexpected curve formation, heavy noise or absence of a
channel. If a problem is diagnosed it will not be immediately obvious whether it is caused by the camera
board and/or the CCD sensor. Therefore, several solutions present themselves. In the majority of cases
an exchange of the camera board will yield the result desired. This methodology has the advantage of
retaining the optical alignment of the camera.

All activities have to undertaken in accordance with current ESD regulations!
Remove the two screws of the EMV camera housing and lift lid.
Pull the post connector from the board (1x for SCAMAX
®
2600 and 2x for SCAMAX
®
4000 ) and un-screw
the four plastic nuts.
Using a pair of pliers pull the board backwards out of the housing by the earth straps. Ensure the board is
pulled squarely out of the housing; otherwise the CCD sensor's contact pins will be bent.
Carefully insert the new board and fasten using the plastic nuts.
