10.12 Handling the Optical Components
If the optical components of the printer are mishandled, image defects or beam
detection errors can result. Beam detection errors are immediately detectable,
but image defects may go unnoticed and show up later as a problem. Replace
any component that you suspect is damaged.
The following types of damage can occur to the optical components:
• Mechanical damage is caused by dropping or other forms of rough handling
or by misadjustment of the mirrors or lenses in the optical cavity.
• Contamination damage of the mirrors or lenses is caused by the biological
oils and acids found in fingerprints. Some mirrored surfaces are affected
more than others. The oils cause a decrease in beam intensity. The acids
can etch, stain, and over time deteriorate the surface of a mirror or lens.
• Electrical damage is caused when static electricity discharges through
sensitive electronic components. Always use the antistatic equipment.
Warning:
Use of controls or adjustment procedures other than those specified
in this manual may result in hazardous laser light exposure to yourself or to
other persons in the room. The safety information presented in Safety Warnings
only applies while the scanner cover is fully installed.
Before servicing the optical components, you must have attended the training
specified in Section D.1.
Table 10–1 gives a short description of each part. Figure 10–1 shows the
locations of various components within the optical cavity.
