getting photoshop CS5 extened to recognize canon 8800F scanner from Import

I cannot get photoshop to recognize my scanner from the Import tab. Previous photoshop 3 allowed me to scan directly from Import. I have updated drivers for scanner.  Any suggestions?

Are you able to scan from another app, such as the built-in Paint applet or one of my favorite freebies, IrfanView:

This will help us to isolate whether it's a scanner-related problem or a Photoshop problem. Also, what kind of scanner is it (make and model) and how is it connected (USB, parallel, SCSI, wired LAN, wireless LAN, et al.)? Regards, Joe

Hi Joe,

I was able to scan from irfanview, thanks

OK, good to know that IrfanView works. IrfanView allows you to select the source...the File menu item is called <Select TWAIN Source>, but it allows you to select TWAIN or WIA sources. I don't have Photoshop...does it allow selection of TWAIN or WIA? If so, have you tried both? I've seen cases where one of them works and the other doesn't. Btw, my first suggestion in situations like this is to update to the latest-and-greatest drivers from the scanner manufacturer's's incredible how often that solves the problem...but you said that you've done that, and I don't want to insult you, but are you certain that you've upgraded to the latest driver from the Canon site...and with the correct version for your OS (including whether it's 32-bit or 64-bit)? Speaking of that, what OS are you running?

My second suggestion is usually to update the firmware, but the Canon site says that no firmware updates are available for that scanner:

My third suggestion is usually the USB cable...amazing how many times that's the culprit...but in this case, since you can scan with IrfanView, I don't see how the cable would be the problem. This is a perplexing one! Regards, Joe

thanks Joe, I've done all the above and cables are ok.  Must be the essentials. Will have to buy the full photoshop.

Makes sense. I can't think of anything else. Good luck! Please post again to let me know what happens – I'm curious!
