Cleaning the optics
Optics include the
imaging guides, camera glass covers
and
sensors
. All of the optics components should be cleaned at the same
time.
NOTE: The lamps are not part of the optics. The lamps (LEDs) should
not be cleaned with wipes or solvents.
Cleaning the imaging guides and camera glass covers
To prevent streaks in images, reduced OCR/ICR/Barcode recognition
rates, blurred images, etc., you should clean the imaging guides every
50,000 pages.
The two imaging guides which are inside black, plastic frames are
located in the top and bottom transport trays. When removing a imaging
guide for cleaning or replacement, the entire assembly (imaging guide
and frame) are removed and replaced as one piece.
Clean the camera glass covers at the same time you clean the imaging
guides.
CAUTION: Do not remove the imaging guide from the black frame.
1. Open the transport cover.
2. Gently pull the 2 fastening clips that secure the top imaging guide
towards the front of the scanner to release and remove the imaging
guide from the transport.
3. Spray the glass cleaner on a lint free cloth, taking care that any
overspray does not fall inside the scanner.
4. Wipe down both sides of the imaging guide. Be careful not to touch
the cleaned glass.
