4 PREVENTATIVE MAINTENANCE
4.1 DAILY
As a start-up check each day, inspect the scan window daily (or more often if conditions warrant
it). If dirty, clean it using a clean soft lint-free cloth and glass cleaner. When cleaning the scan window,
great care should be taken to not use so much glass cleaner that it could seep down the edge of the scan
window glass. This could result in it accumulating on the underside of the window, drying, and leaving
a residue that would require cleaning the underside of the scan window.
Also, each day, with the scanner powered-on, be sure all cooling fans are operating. It is very
important that all these fans are operating. One fan is located on the back panel and two are inside the
unit. One is mounted under the card rack and the other is mounted on the cover for the power supply
assembly.
4.2 MONTHLY
4.2.1 Clean Filters
Once a month (or more often if conditions warrant it), remove the metal mesh filter located in the
bracket on the left inside panel of the scanner. Wash the filters in warm water, air dry them, spray them
all over lightly with filter spray (A64168), and reinstall them.
4.2.2 Clean Camera Lenses
Each month, clean the camera lenses with regular photographic camera lens brush or air duster.
Be sure you do not hold the lens while cleaning.
4.3 ANNUALLY
Each year, on the anniversary of the initial installation, perform the following tasks in order.
4.3.1 Clean CCD Camera
Clean the CCD array on the camera, located in the center of the Camera Board with an air duster
or cotton swab.
