FAQs

I plugged the scanner to my computer but the scanner is not detected.
Make sure the USB cable is fully connected to the scanner and your computer. You may want to try inserting the USB cable into another USB port on your computer.

I have installed the scanner to my computer but I can’t get it to work.
You should always reboot your computer after final installation. Before scanning you should first select the scanner source and then calibrate the unit before scanning.

I can scan with the scanner but the image output is totally black.
Calibrate the scanner with the calibration sheet that came with the scanner. If your calibration sheet comes with black horizontal bars then they must face down when calibrating.

I can successfully scan but I see some black vertical lines from the top to the bottom of the image.
Calibrate the scanner with the calibration sheet that came with the scanner. Make sure the black bars are facing down when calibrating if your calibrating sheet comes with them.

How do I upgrade my scanner driver?
First download the latest driver. Unplug the scanner, run the setup.exe file and follow the directions to install the driver. Once the installation process has completed, plug in the scanner.

Can my scanner scan transparency or film?
No, they are not designed for this task.

What is the difference between using SDK vs using TWAIN in my software development?
The SDK provides a DCT-specific interface that is standard for all of our scanner models. It provides a relatively simple C language API to control all aspects of the scanner. Documentation, sample code, and developer support can be provided upon request.

TWAIN is a standard scanner interface. It provides a scanner control UI but also supports UI suppression for applications that want to use a custom UI. Documentation, sample code, and developer support are provided by the TWAIN Working Group at TWAIN.org.
