Cleaning the Inside of the Scanner (ADF) with a Cloth

The inside of the ADF can be cleaned with a piece of cloth moistened with Cleaner F1, or a sheet of Cleaning Wipe.

As the scanner continues to feed the documents, paper dust will accumulate inside the ADF and it may cause scanning errors. Cleaning should be performed approximately every 1,000 sheets scanned. Note that this guideline varies depending on the types of documents you scan. For instance, it may be necessary to clean the scanner more frequently when you scan documents on which the toner is not sufficiently fused.

The inside of the ADF becomes very hot when the scanner is being used.

Before you start cleaning the inside of the ADF, make sure to turn off the power, unplug the power cable and wait for at least 15 minutes for the inside of the ADF to cool down.

ATTENTION

Do not use water or mild detergent to clean the ADF.
It may take a long time to dry if an excessive amount of Cleaner F1 is used. Use only a small amount. Wipe off the cleaner completely to leave no residue on the cleaned parts.

Turn off the scanner, unplug the power cable and wait for at least 15 minutes.

For details, refer to How to Turn the Power OFF.
