Adjustment Procedure
Do not loosen the camera. The construction of the camera ensures that the optical axis of the
lens is perpendicular to the scanning area and hence no alignment of the camera housing is
necessary.
Always perform the Focus adjustment before adjusting the Scan-Width, see “Interaction”
below.
Start SCANtest 6

Press Execute

Scan-Width before continuing.
