The "Check" lamp lights or "Device Error" appears when scanning documents.

The probable causes are as follows:

• The optical unit (lamp, lens, glass, CCD etc.) may not be clean and shut the light.
  Please clean the scanner by referring Operator’s Guide.
• The light volume of the lamp is not enough.
  The lamp may be getting old. Please replace the lamp.
• The documents may be stuck in the scanner.
  Please remove the documents.

If the error message still appears, please contact the distributor/dealer which you purchased your scanner from.

Please see the page of the nearest distributor/dealer.
