Clean the platen glass and the underside of the Feeder

warning:

When cleaning the machine, first turn off the main power switch, and disconnect the power cord. Failure to observe these steps may result in a fire or electrical shock.

note:

If the platen glass or the underside of the feeder is dirty, the original may not be scanned clearly, or the size of the original may be detected incorrectly.

attention:

Do not dampen the cloth too much, as this may damage the original or break the machine.
