Replacement
procedures
Replacement procedures should be performed on an as-needed basis.
Components that need periodic replacement include the air filter,
exposure lamps and the imaging guides.
Replacing the air filter
The air filter should be replaced at least once a year, more often if
needed.
IMPORTANT:
Never operate the scanner without an air filter installed.
The imaging apparatus will quickly become
contaminated with dust and dirt, impairing image quality.
1. Remove the air filter cover by pressing in on the top of the cover to
release the catch.
