Care and maintenance
Cleaning the scanner
In order to maintain the best image quality and prevent dust
accumulation, clean the outer casing, image sensor and roller inside
the scanner regularly (about every 50-100 scans, or whenever
unwanted vertical/horizontal lines appear on scanned images).
WARNING : When cleaning, use only the recommended and
supplied tools. Do not use any tools other than those supplied
to clean the image sensor inside the scanner. Otherwise it will
be permanently damaged.
Cleaning the outer casing
Please follow the instructions below to clean the outer casing of the
scanner when necessary.
1. Use a suitable dust blower to blow off the dust on the scanner.
2. Use a slightly dampened cloth to wipe off any smear on the
surface of the scanner.
3. Wipe the scanner with a dry and clean lint-free cloth.
WARNING : Do not use any solvents or corrosive liquid (for
example, alcohol, kerosene..., etc.) to clean any part of the
scanner. Otherwise the plastic material will be permanently
damaged.
Cleaning the image sensor
1. Follow the instructions above to clean the outer casing of the
scanner first.
2. With the scanner power off and
disconnected from the computer,
insert the sensor cleaning swab
into one end of the output slot.
NOTE : Make sure that
there is no visible dust on
the swab before inserting it
into the output slot.
