Maintenance
Scanning glass and rollers
Clean the scanning glass and rollers frequently to ensure the quality of
transmitted images and copies. Open the operation panel (pull the
release marked PANEL RELEASE up), and wipe the scanning glass
and rollers with a soft cloth.
Make sure that all dirt and stains (such as correcting fluid) are
removed, as dirt and stains will cause vertical lines on transmitted
images and copies.
Adhesive cellophane tape is useful for removal of debris from the
rollers.
The housing
Wipe the external parts and surface of the machine with a dry cloth.
Caution!
Do not use benzene or thinner. These solvents may damage or
discolour the machine.
