No TWAIN sources in Photoshop 7.0.1

I have recently reinstalled my Photoshop 7.0.1 and suddenly I can no longer see most of TWAIN sources in the File|Import submenu. In the previous Photoshop 7.0.1 installation I used to see a dedicated TWAIN entry for each scanner that I have connected to my Windows XP machine – Canon FS4000US and Epson Perfection 1660, but now they are both gone. Only one TWAIN source that’s left in the submenu is that Windows XP’s unified TWAIN source (WIA). Does anyone have any idea about how I can restore individual TWAIN entries for each device in Photoshop’s File|Import submenu?

Other TWAIN applications that I have on my machine use the more traditional ‘Select TWAIN Source/Aquire’ approach to TWAIN user interface. And "Select TWAIN Source" dialog lists all individual TWAIN sources without any problems, i.e. I can see three individual TWAIN sources there – Canon, Epson and WIA, which suggests that there are no problems with TWAIN subsystem itself.

I tried to uninstall and reinstall TWAIN drivers for both scanners to no avail.

Photoshop just enumerates through all the TWAIN data sources available just as it has before, only now the sources are put directly in the Import menu instead of requiring you to pick "select source" then pick the source.

If you have Photoshop 6, do you see all the sources there? It used the older method of explicitly picking from the data source manager.

Marc, IMO Adobe should go back to the way PS6 did it. PS7 takes long enough to boot as it is, the TWAIN enumeration adds 5-10 seconds (and in some cases, much longer).

Rick – if the TWAIN source is working correctly, then enumerating the sources takes less than a quarter second on a PIII 700 Mhz system.
If they aren’t working correctly, then it can take some time.

I’m running just two sources, MagicScan 4.5 and Vistascan 3.1, and even though both work flawlessly from PS7.01, enumeration takes almost ten seconds on a P3-850MHz/SCSI Ultra160 system.

Is there anything I can do to minimize PS7 load times?

Thanks,

Are the devices for both of those drivers connected?

If not, then one of them could be hanging up looking for the device (which also indicates that it contains some sloppy code).

Since I don’t know which devices you have connected, or which devices those drivers belong to, I can’t narrow down which might be causing the delay. If I recall correctly, both drivers are for Umax scanners – so there could also be some conflict by having both present.
