Chapter8 Maintenance
8.1 General Maintenance
Caution-
Before any maintenance work takes place, ensure that the power supply has
been switched off and the system is powered off.
All maintenance work must be carried out according to the safety regulations.
In order to ensure the maximum availability and lifetime of the system, we recommend you regularly
check the ventilation and keep the surrounding area clean.
8.2 Cleaning the Field lens
This system is fitted with high quality optical components, which under normal operating conditions are
maintenance free for their lifetime. However, it may be necessary to clean output lenses, e.g. the
scanner flat field lens (f-theta objective) if it becomes covered in dust or fumes.
1. Never touch the optical components with your fingers! Oily or dirty hands may damage the lens
surfaces.
2. Do not use any tools or hard objects to clean the surfaces. Scratches cannot be repaired.
3. To remove larger pieces of dirt, only use a lens cleaning cloth with high proof (min. 98 %) alcohol.
4. Do not dip the cleaning cloth in the cleaning solution. This contaminates the solution and makes it
unusable. Place drops of the solution on the cloth!
5. Distribute the cleaning fluid carefully using small circular motions. Start at the center of the lens and
move outwards to the edge. Keep moving the cloth until the entire surface is clean.
6. Do not wipe the lens with a dry cloth. Do not touch the reverse side of the cloth.
7. Do not exert any pressure on the lens.
8. Clean once half a year (depending on usage).
The End.
