Sometimes your computer may generate an error indicating a Twain scanner error. This problem can be caused by a number of reasons.

g.Twain is actually an acronym for “interesting unnamed technology.” The Twain standard is used to accurately extract images from a scanner or digital camera in a software application that understands this method.




Back to one more hourthen the question asked from our technical support team.

“I am trying to scan a document, but I still get a TWAIN error.”

Problems with the TWAIN driver, indicating that the computer does not recognize the reader driver and the Scan Workstation reports the problem. However, problems with the TWAIN driver are not caused by the scanning workstation.

The TWAIN driver is software that controls the communication between the PC and the best scanner.

Updating or restarting the scanner may cause the new scanner to no longer recognize the TWAIN driver. To fix this problem, your company should try the following:

  • Try restarting each of our scanners, or unplug the scanner from the workstation and plug it back in.
  • Open TWAIN, the driver that you installed with your scanner, and check these specific scanner settings.
  • Update the TWAIN driver from the manufacturer’s website. This
  • Make sure other applications can scan on your computer.
  • Uninstall the scanner software and even reinstall it.
  • If there is no reason to fix the TWAIN error, contact your scanner manufacturer for device-specific fixes.

    This is a general TWAIN error. This usually means that the main scanner is disabled or some other internal problem with the scanner.

    Check the analysis first to see if it is derived and restart to fix the problem.

    If it runs out, this does not solve the problem, it will be considered that the scanner has another problem. For example, a document feeder or a problem.

    These types of errors are not detected by TWAIN, so EzeScan does not support this situation. EzeScan

  • Download

    1. Close the vendor’s scanning utility (usually supplied with the TWAIN driver), for example: for Kodak this is the scan validation tool, for Fujitsu this is ScandAll.
    2. Perform the exact same scan as you were in EzeScan. After that, the scanner application should display another message describing our problem.
    3. Please accept this information and provide a support channel from your vendor forshields.

    If the problem is not serious when using the utility and when using EzeScan, it is most likely an EzeScan problem.
