  First, ensure the scanner is turned on. If the problem persists, try reattaching the USB or IEEE 1394 card, setting it up, and reinstalling the corresponding driver. You may also need to replace the cable or check the supply voltage and replace the power supply if necessary. As a last resort, consider replacing the data controller board or IEEE 1394 board, and reinstalling the boot program.

  William FrancoAug 21, 2025
  This issue may occur due to several reasons. First, perform a calibration (white correction). Check that the image sensor cables are properly connected, with no broken wires. Also, check the +5 V power supply and replace it if it is faulty. Replacing the data controller board or the image sensors may also resolve the issue. You can also try adjusting the “Intensity (Brightness)” in Scanning Master 21+.

  If the document is not transporting correctly, open the center cover and remove any foreign objects. Check for anomalies around the control boards and the motor. Also, check the power supply and replace if necessary. If these steps don't resolve the issue, consider replacing the control boards or the main control board.

  James WilsonAug 30, 2025
  If the document is not being scanned even when in the scanning position, check the document detection photosensor. Ensure the cable is properly connected. Verify the correct DIP switch setting for your specific model. Use Scanning Master 21+ to specify the correct scanner model. If all else fails, replace the main control board.
