This is not a question about MATLAB.

Hi Rizqi,

As per my understanding you are experiencing issues with accessing scanner using CMD TWAIN in MATLAB. Here are some workarounds that can be explored to troubleshoot and potentially resolve the issue:

1. Check MATLAB Compatibility: Ensure the version of CMD is compatible with the version of MATLAB in use. Refer to compatibility information on the CMD TWAIN download page or in its documentation.

2. Update Drivers: Ensure the scanner drivers are up to date. Can find the latest drivers on the scanner manufacturer's website.

3. Check MATLAB Path: Ensure that CMD TWAIN files are correctly added to the MATLAB path. Add path using “addpath” function in MATLAB.

addpath('C:\path\to\cmdtwain');

4. Test CMD TWAIN Outside MATLAB: Test CMD TWAIN functionality outside of MATLAB to ensure that the issue is not MATLAB-specific. Use a simple command prompt or a different application that supports TWAIN to test the scanner.

5. MATLAB Error Messages: Pay attention to any specific error messages MATLAB provides when using CMD TWAIN. These messages can give clues about what might be going wrong.

Refer to the CMD TWAIN documentation for any specific troubleshooting steps or known issues. If none of the above steps resolve the issue, consider reaching out to CMD TWAIN support or the scanner manufacturer's support for further assistance.
