Maintenance

Regular scanner maintenance will keep the scanner working properly.

There are three basic maintenance tasks:



Cleaning the scanner

How often you need to clean the scanner will depend on how much it is

used and the condition of the media. Newspapers and old blueprints

will make a scanner dirty much faster than new brochures and CAD

plots. Be sure to clean the scanner when you notice a reduction in the

quality of the images. Particles of dust in the scan area will show up as

streaks in the image.



Calibration and camera alignment

Calibration sets the camera alignment and black and white levels and

is carried out using the calibration sheet. IMPORTANT: Make sure the

scanner is clean before calibrating.



Replacing worn parts

This should be carried out if you see a warning on the screen or a worn

part affects the image quality e.g. lines in the image from a badly

scratched glass. User replaceable parts (consumable parts) are:



the glass plate assembly



the white background
