I'm not sure what the issue could be, but when I try to use NAPS
which is what this program is using in the background to scan
directly to PDF, it seems to work fine. It also gives me 1 scanner
choice. Surely these days we should be using twain as a standard?
Very best wishes,

Is this add-on too limited? Does it specify only WIA, or is that
the result of how the scanner itself is already set up to
communicate with the computer? I wonder if the scanner doesn't
work with the add-on because the scanner isn't set up to use WIA.

I have only just gotten around to trying this add-on. I am
running the latest version of NVDA with Windows 10 21H2. My
scanner works fine with other programs such as windows fax and
scan and DocuScan. However when I try to scan a page from the
scanner with this add-on, I receive the following error.
TesseractOCR dialog Scan error
Process wia-cmd-scanner failed:
Scanning to file C:\Users\Mobeen (dpi = 300, color mode 'GRAY',
output format 'JPG')
Exception occured: Access is denied. (Exception from HRESULT:
Please make sure your scanner is WIA-compliant and can scan in
another application before trying again!
I am then prompted if I want to scan another page. When I click
no, the program keeps beeping with no way to cancel the process
until NVDA is restarted. This is quite annoying. Is there any
way around this error? Also in the next version, could you
please consider adding a cancel keystroke or cancel button in a
window? It would be a real shame if the only way of cancelling a
scan job was to restart NVDA. As far as I know, I have all of
the relevant drivers installed. It sounds like the add-on is not
running with admin privileges or isn't able to save and process
Very best wishes,
