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 5,000 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.

  1. 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.

  2. Open the ADF.

    For details, refer to How to Open the ADF.

    When the ADF is open, it might close accidentally. Be careful not to get your fingers caught.

  3. Clean the following locations with a cloth moistened with Cleaner F1, or a sheet of Cleaning Wipe.

    Cleaning the Brake Roller
    Pick Roller (× 2)

    Gently wipe off any dirt or dust along the grooves as you rotate the roller manually, taking care not to damage the roller surface. Make sure that it is wiped properly because black residue on the rollers will affect the feeding performance.

    Plastic Idler Roller (× 4)

    Gently wipe dirt and dust off the roller, taking care not to damage the roller surface. Make sure that it is wiped properly because black residue on the rollers will affect the feeding performance.

    Be careful not to damage the sponge that is attached to the plastic idler roller.

    Glass (× 2)

    Gently wipe dirt and dust off the glass sections.

    ATTENTION

    • Vertical streaks may appear on images if the glass section is dirty.

    • When you receive a [Clean glass!] message from Notification on the touch screen, check which glass section is dirty and clean it.

      When a [Clean glass!] message shows that the glass section is dirty only on the one side, the message may not disappear even if you clean it. In that case, clean both glass sections.

    Ultrasonic Sensor (× 2)/Document Sensor (× 8)

    Gently wipe dirt and dust off the surface of the ultrasonic and document sensors.
