7.1 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.
The three 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, start the Scanner
Maintenance program and let the wizard take over as it performs camera alignment and
calibration.
The tools for scanner maintenance were supplied with your scanner - including the program that
will check your scanner and guide you through the maintenance steps. Be sure to install the
Scanner Maintenance program from the WIDEsystem TOOLS CD-ROM. For best results, run
the maintenance procedures right after setting up your scanner for the first time.

7.2 Cleaning the Scan Area

A clean scan area is vital for optimal results.
In order to access the scan area for cleaning or other maintenance purposes, you have to free
the pressure-platen. On some scanner models, the pressure-platen is completely detached
from the scanner. On scanners with Automatic Thickness Adjustment Control (ATAC), the
pressure-platen is fixed inside the scanning area lid and you just have to open it. Cleaning
instructions for each scanner type follow below:
Caution: do not use abrasives, acetone, benzene or fluids that contain these chemicals.
Do not spray liquids directly onto the scanner glass-plate or anywhere else in the scanner.
Caution: Before cleaning the scan area, be sure to turn the scanner power off and
disconnect the power plug.
NOTE: be sure to also clean the scanner's flat surface so dirt and dust are not dragged into the
scan area with the original.
