6.1 Step by Step Procedure for General Maintenance
6.1.1 Remove Top Cover
Disassembly and Assembly, see Chapter
8, page 156.
6.1.2 Cleaning of the Scanning Area
The following parts are cleaned using a soft lint-free cloth wetted with a mild cleaning
detergent. Alternatively, the parts may be cleaned without the use of cleaning detergents by
using a damp microfibre cleaning cloth (wet the cloth with water and wring until damp).
• The White Background Plate on the Original Guide Plate.
• Both sides of the Glass Plate.
On 2- and 3-camera scanners, be careful not to push the Stitching Wire
(located under the Glass Plate) out of position.
Do not use solvents, as this may dissolve the paint used for the black masks
on the glass plate.
• The Mirrors.
It is necessary to remove the Mirror Chassis, see Section
8.10, page 159, to
get access to the mirrors for cleaning. The Camera Adjustment must be
checked and if necessary readjusted after replacement of the Mirror Chassis.
Note: The mirrors are “out of focus” and small dust particles on the mirrors
do therefore not deteriorate the scanning result.
• The Feed Rollers.
May be cleaned with a damp microfibre cleaning cloth.
6.1.3 Fluorescent Lamp
Check the fluorescent lamp for signs of wear, such as darkened ends or discolored (black
stained) tube.
If there are signs of wear, the lamp should be replaced, see Section 9.4, page 162.
6.1.4 Check Lamp Driver Adjustment
Procedure, see Section 3.4.2, page 30.
Check and if necessary readjust the Lamp Driver.
