Cleaning The Scanner Components - Canon B740 Manual

Cleaning the Scanner Components

Follow this procedure to periodically check and clean the scanner components:
1
Disconnect the power cord from the
copier/fax.
2
Open the operation panel partially by
gently pulling it toward you.
• It only opens slightly.
3
While holding the operation panel
open, clean these components:
• Separation guide and separation roller
Wipe with a clean, soft, dry, lint-free cloth.
• White sheet and scanning glass
Wipe with a clean, soft, lint-free cloth
moistened with water, then wipe with a
clean, soft, dry, lint-free cloth.
n
•
If the scanner components are dirty,
the documents you send or copy will
also be dirty.
• Be sure to use a soft cloth to avoid
scratching the components.
c
Do not use tissue paper, paper
towels, or similar materials for
cleaning; they can stick to the
components or generate static
charges.
4
Clean the shaded area of the operation
panel.
• Dirt and dust particles that collect on the
underside of the operation panel affect the
quality of the documents you copy or send.
