On a Gateway, Pentium 233, Windows 98, why would OCR and graphics programs suddenly be unable to access my HP Scanjet 4100C. The error message says: "Can't open TWAIN source: HP PrecisionScan LT 1.02.
This all started when my OCR program, Abby FineReader, gave me that error message. I had used it successfully about 9 months before, so I know it's not the OCR program. Then their hotline had me try to access the scanner through a graphics program, and sure enough, Paint Shop Pro gave me the same message. As the message shows, both programs know what they are trying to access; they just say they can't.
Reinstalling the scanner did not help. Nor did the updated scanner software, including TWAIN driver. Nor did the updated version of the OCR program. I am also stymied because HP conveniently no longer supports the 4100C, but I do feel that the problem is not their driver. Oh, the scanner works fine. Their software works fine. I just can't access it through other programs, which comes down to the TWAIN driver.
So, what changes have I made since I used the OCR program 9 months ago. Probably lots. But only one thing seems relevant. I tried to set up a fax program. I was instructed to go back to my Windows 98 disk to find a Windows 95 program:
"Where is MS Fax?
On the W98 disk in toolsoldwin95messageus are 3 files: wms.exe and awfx.exe and wms-fax.txt.
run wms.exe. This will install Windows Messaging. Then run awfax.exe, this installs Winfax Lite.
You'll also find a wms-fax.txt file in that folder, you should read that first. 20 July 1998"
I think this might be connected with my current problem because though I could fax text files, I could not get the fax program to run the scanner -- so this might be when it started. Or it could have started before then, who knows.
Anyway, if anybody knows anything about TWAIN troubles, your help would surely be appreciated.
