TWAIN compliant device not installed
Posted on 2011-10-11
I am having an issue with a scanner that has been installed on a Win7 32-bit workstation. We had a printer/scanner A previously added to the machine. Life is good. Added Printer/Scanner B a month later and life is still all good. No issues with printing or scanning from either device.
A month after scanner B was added, an error message started to appear:
"There is no TWAIN-compliant device installed"
Scanner B is a HP CM2320nf MFP. NO new devices have been installed since the installation of scanner B.
Why would the TWAIN error come up after no issues for one month and no new device or software being added?
