8.1 Preliminary Maintenance – scanner setup
On scanners:
When you have setup your new scanner and verified your installation, it is important that you run
your first maintenance session before working with the scanner. Shipping and transportation can
affect the cameras and it is therefore highly recommended to calibrate. But before you do so,
you must thoroughly clean the scanner. Preliminary Maintenance is just the very first session of
regular scanner maintenance and involves the same steps. Follow the instructions in the next
section under Regular Scanner Maintenance.

8.2 Regular Scanner Maintenance

Regular scanner maintenance is a sure way to minimize costly downtime. The three routine
maintenance procedures cleaning, camera alignment and calibration will improve image
quality and reduce your service costs.
NOTE: Camera Alignment is not relevant with 18" scanners.
The maintenance functions are closely entwined and they should all be performed in a single
maintenance session, starting with cleaning the scan area and ending with calibration. The
reason for this is simple. If you clean the glass or adjust the cameras then you will have changed
conditions in the scanning area and will need to calibrate in order to readjust black, white and
color interpretation. This works the other way as well – scanner calibration must always be
preceded by cleaning and camera alignment to get reliable calibration results.
Scanner Maintenance is very easy to perform and most of it is completely automatic. After
manually cleaning the scan area, you just insert a Calibration Sheet, and start the Scanner
Maintenance program.
On some scanner models you can activate the Scanner Maintenance program from the iJET
Panel. On others you must run the Scanner Maintenance program from a PC that recognizes
the scanner and has WIDEsystemNET and Scanner Maintenance software installed. See the
following section on Running the Scanner Maintenance Program for details..
