Question about Canon CanoScan N1220U Flatbed Scanner
Have used my N1220U scanner for years on my XP computer. I have a second identical scanner, and both give the same results. Both were working until recently. I am not aware of any changes I have made to affect their operation. They go through the normal startup routine. The computer will run a test which cycles through a normal scan cycle, and reports that they are working properly. I have re-loaded the software, and have deleted the device and re-installed it. They are recognized by the computer when I plug them in, and perform the normal startup routine, but pressing the "scan" button does nothing at all.
You have to decide how much trouble you are willing to put into this problem. At this point you have deleted and reloaded the software and drivers, which is the most typical fix. The self test says it is functional but it does not physically test a bad switch. A replacement of this same model sells for under $30, including shipping, on ebay. CNET reports a release date of June 10, 2002. It may be time to move on since it cannot be repaired for the cost of a replacement.

SOURCE: Tvichw32 Driver Open Error
Hello Aunt Pat
(01) Is this scanner "new" to the computer it is installed on now (where you're experiencing these issues)?
(02) Did this problem show up w/out apparent cause or relation to any recent changes on your system (e.g. New hardware or software installed, updated, upgraded or removed; system crash; computer repair; etc.)?
(03) Did the problem appear soon after a change to your system? (see above examples)
There are many references to this issue on the Internet. I've listed a few here. You can find many more, if you like, by performing search engine queries.
THIS links to a Roxio forum thread regarding this issue. (Even if you aren't using Roxio software, the information here could be relevant to your issue.)
THIS link will explain a bit about what TVICHW32 driver is.
I'd reinstall the ASPI drivers. A driver file may have become corrupted. (Assuming you'd been using this scanner successfully on this system until recently.)
You can find links for Adaptec's ASPI drivers on their web site HERE. They also have an ASPI version checker you can run to find out what verison is installed on your computer.

Since you have had the scanner a while, you may not have a recent enough driver to work well with XP: until I smashed my 9950F, I was scanning under XP with the ScanGear CS 10.324a driver with no problems (the driver is dated 22 June 2007). You can download it from several sources on the web, I used
Other than that, they report some issues if the system drive is NTFS, but I was using NTFS for my system (and only) drive, so I don't see any reason for this to be your problem.

Testimonial: "So what you are telling me is that the scanner is now useless on my PC using Vista. Is this correct?"
The one you want is the CP Upgrade 3090
Hope this helps
Please leave feedback
