Determine if a scanner is TWAIN-compliant

Scanning into Onvio requires a TWAIN-compliant scanner. If your imaging device is not being recognized or is experiencing other issues scanning into Onvio, you can perform a test outside of Onvio to see if your scanner is TWAIN compliant and the driver is functioning properly.

Twacker

Not every scan job you perform locally on your machine will utilize the TWAIN driver, we recommend using Twacker, a third-party utility to test the compatibility of your driver. It can be downloaded in the Tools section on TWAIN.org External link (What's this?) select the 32 or 64-bit version depending on your computer's operating system.  You can also download Twacker here External link.

  1. Launch Twacker.
  2. Choose File > Select Source and select your device from the list.

    Note: You can try these steps if your device is not listed.

    • Verify your device is on and connected to your workstation.
    • Run Twacker as Administrator.
    • Check to see if the appropriate driver is installed. Contact the device's manufacturer and/or your qualified IT professional for assistance with this.
  3. When your scanner is selected, choose File > Acquire.
  4. In the scanner dialog for your device, select your settings and scan a document.
  5. If the scan completes successfully without errors, the document you scanned appears in the Twacker window, indicating that your device is functioning properly and is TWAIN-compliant.

    Notes

    • If your scanner does not work with Twacker, it is likely that it will not work with Onvio. Consider installing the most current TWAIN driver for your scanner model from the manufacturer's website.
    • If you need assistance with that process, or other related steps to resolve any issues with your TWAIN driver(s), contact your device's manufacturer and/or your qualified IT professional.

Internal notes


If you need to install Twacker yourself, or need to send it to the firm rather than having them download from the TWAIN.org website. You can download the -Twack_32.zip file and unzip it. Copy and paste the Twack_32.exe file to your Desktop before running it or attaching it to a message.

Note: If sending this file to a user, you may need to rename it first because email will most likely block .exe attachments. You can also utilize the SendThisFile utility or the MKT Secure Data Exchange.
