6.3Cleaning the Inside of the Scanner
Clean the inside of the scanner with a cloth moistened with Cleaner F1.
After the scanner has been in use for a period of time, its inside will be contaminated with paper debris and dust. The accumulation of debris and dust may cause scanning problems.
As a guideline, clean the ADF at least every 1,000 scans. Note that this depends on the type of the documents scanned. For example, the ADF must be cleaned more frequently if documents are scanned when the ink has not been sufficiently fixed on the paper.
Clean the ADF according to the following procedure. (Refer to the illustrations on the following page.)
CAUTION
The glass surface inside the ADF becomes hot during the scanner operation.
Before you start cleaning, disconnect the AC adapter from the outlet and wait at least 15 minutes for the scanner to cool down.
ATTENTION
•Do not use water or neutral detergent to clean the inside of the scanner.
•Do not use compressed air to clean the scanner. Compressed air cause dirt and dust to enter the scanner, which may result in scanner failure and mal- function.
