Forums › TWAIN Classic › HP 3390 – SCAN issues – both Twain and WIA
Hi. I have a problem that seems orphaned by both HP and Microsoft. I tried to install an HP4050 scanner on a machine that already had a HP 3390 multi function device. I had multiple issues with scanning quality on the 3390. Now HP advises me not to install both products on the same machine. I have now been trying for several days to uninstall the 4050 and reinstall the 3390. I have done the various “clean” uninstalls, with direction from HP. I still have two problems – poor quality B&W scans and the 3390 does not show up in “Scanners and Cameras” in windows. The latest issue is that when I try to scan to TWAIN using, say, Adobe Acrobat, the product wants a scan.msi file. I have found that one on my HP install disk – but it doesn’t like it. I also did a windows restore.
So… long winded – I think I need both TWAIN and WIA drivers or software. Any thoughts? Thanks…G
