Parts List on
PL 14.20
Purpose
To clean the optics components of the scanner ensuring optimum image quality.
NOTE: This adjustment must only be performed if directed to from an Image Quality RAP, or if
the optics cavity was opened to install a new component and contamination can be seen on
the optics components.
Procedure
WARNING
Ensure that the electricity to the machine is switched off while performing tasks that do
not need electricity. Refer to
GP 14
. Disconnect the power cord. Electricity can cause
death or injury. Moving parts can cause injury.
CAUTION

.
2.
Inspect the cleanliness of the optics mirrors, if necessary, clean them as follows:
a.
Vacuum clean the area to remove all visible contamination, taking care not to touch
the mirrors with the cleaning nozzle. It may be necessary to move the carriages to
gain reasonable access, do this by hand rotation of the flywheel on the capstan
shaft.
b.
Wash your hands.
c.
Carefully clean the mirrors using a dry micro fiber wiper,
