Cleaning the Inside of S1100i

Scanning repeatedly may cause dust and paper dust to accumulate inside the ScanSnap resulting in a scanning error.

As a guideline, the inside of the ScanSnap should be cleaned every 100 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.

Before you clean the ScanSnap, you must close the feed guide, turn off the ScanSnap, and unplug the USB cable. Not doing so may cause fire or electrical shock.
Do not use aerosol spray or spray that contains alcohol to clean the scanner. Paper dust and other dust blown up by strong air from the spray may enter the inside of the scanner which may cause scanner failure or malfunction.
Also note that sparks generated by static electricity may cause a fire.

ATTENTION

Do not use water or mild detergent to clean the inside of the ScanSnap.
It may take a long time for Cleaner F1 to dry if an excessive amount is used. Moisten the cloth with moderate quantity.
Wipe off the cleaner completely to leave no residue on the cleaned parts.
