There are a number of things that can cause problems on the SCSI bus. First of all make sure that you are using at the least an active terminator, better yet a forced perfect terminator.
Second, make sure you are using a good quality cable. There are allot of cheap knock offs out there and they will cause havoc with the SCSI bus.
Third, be sure that you do not use ID7 on the scanner, the SCSI card is defaulted to that address.
Fourth, make sure that the SCSI card is terminated.
Fifth, make sure that term power is on from the card and off at the scanner. Also try it at both ends as a last resort.
I used to be a big fan of Adaptec cards but they have sucked for years now and I much prefer the LSI SCSI, SAS, SATA, and FC-AL cards. The 2940 is damn hard to beat for compatibility though and i do highly recommend one.
There is allot more to SCSI than that but check those first.

Hi Mike et al., thanks greatly for immediate response! In order-
1. HP scanner has attached active terminator with reassuring green led.
2. cable is a hefty HP cable
3. card uses ID7 as you say and HP is set to ID5 on the tumbler.
4. Card was plugged into PCI slot 'as delivered'. No instructions in the booklet; I'll dig it out and examine for any options.
5. Now this is interesting as I don't understand what you are saying here. The scanner has a switch option that is either set to a plus (+) or a dot (.). Any guidance on these?
I'm wondering whether it is a matter of processing power; if I set the scan requirements to absolutely lowest 8-bit b&W it sometimes works; if I then ease up the resolution, it freezes permanently. However adaptec's requirements are more than met.
Hope you can help me further! jeffjohn
