The inside of the scanner (ADF) needs to be cleaned regularly for every certain number of sheets scanned. The scanner records the number of sheets scanned so that you can check the number of sheets scanned after you cleaned it last.

The procedure to check the number of sheets scanned is as follows.

  1. On the touch screen, press Settings → [Cleaning & Maintenance] → [Consumable counters].

  2. On the [Consumable counters] screen, check the value for [After cleaning].

    • When the background color of the counter is yellow

      It is about time to clean the scanner.

    • When the background color of the counter is red

      It is time to clean the scanner. Clean the scanner.

To use the Software Operation Panel in order to check the value, refer to Settings Related to Sheet Counters.

ATTENTION

Cleaning cycles may vary depending on the condition of the documents. Also, cleaning must be performed more frequently when the following types of documents are scanned:

  • Smooth-faced documents such as coated paper

  • Documents with printed text/graphics that almost cover the entire surface

  • Chemically-treated documents such as carbonless paper

  • Documents containing a large amount of calcium carbonate

  • Documents written in lead pencil

  • Documents on which the toner is not sufficiently fused
