tyuui
The inside of the ADF becomes very hot when the scanner is being used.
Before you start cleaning the inside, make sure to turn off the power, unplug the power cable and wait at least 15 minutes for 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 and wait for at least 15 minutes.
Unplug the power cable.
Pull up the ADF release tab to open the ADF.
When the imprinter is installed, open the print section of the imprinter first, then the ADF.
