Using TWACKER to test the functionality of a TWAIN driver
Step Action 1
Download the "twack.zip" application package:
2 Unzip twack.zip, locate the TWACKER.exe file, and run the executable. 3
Once the utility is open, click File, Select Source. The generated list will contain all installed TWAIN drivers.
If the driver you wish to test is not listed, it is not installed correctly. Reinstall the driver file to resolve this issue.
4 From the list, select the driver you wish to test. 5
For testing purposes you will have two options:
Scan to File – Click File, "File".
Scan to screen – Click File, "Native". (Note: The scan to screen cannot be saved.)
6 Click File and ensure Show UI is checked. 7 Click File, Setup to change the various settings (resolution, scan mode, etc). 8 Click File, Acquire to initiate the scan. If the driver is working correctly, the scan will proceed normally.
Refer to the printer's service manual for additional troubleshooting steps and for removal/installation procedures.
