Needs expensive software and Canon will not support. Returned to vendor.
2 April 2013
Summary: Many difficulties with attempts toscan documents through it and tried several third party softward OCR programs, to no avail. Contacted Canon for support and they refused to support or recommend anyone that can assist. What a rip! Returned to vendor (whocould not be reached due to holidays)and am awaiting vendor's response now. Forget Canon and its products--No customer service there. Now using a cheap old scanner that at least works. No more Canon products for us.
Summary: I worked like a dog and FINALLY got two scans out of this machine. They look terrific - especially since they were ancient, faded and in really bad shape. But, the positives end there. The software that comes with this thing is buggy as all get-out. Crash, crash, crash! I run Windows 7 (64 bit). I'm used to there being problems with pre-Windows 7 products. But, this one sets the bar for problems!
Summary: Bought Canoscan 9000f in January 2011 and it worked great. The included scanner software is clunky, but it gets the job done. A few days ago, I tried to turn on the scanner and nothing happened. Unscrewed and disconnected the built-in power adapter and put a multimeter on the output. Turns out the scanner won't turn on because the power adapter went bad. Drat! Power adapters do go bad, no big deal. Go to their website to order a new one. No can do.
35mm Film is not really seen at 9600dpi - it's more like 1600dpi
21 March 2011
Summary: I bought this scanner for one reason: the new specification of 9600dpi 35mm scanning. I have an inexpensive 3600 dpi dedicated 35mm film scanner as well as the previous CanoScan 8800F. The 8800F claims 4800dpi film scanning resolution but in reality the images only look sharp when downsized to one third the resolution (1600dpi) - this suggests that Canon is counting the three RGB elements of the scanning element as individual dots of the DPI.
Summary: I own a Canoscan 4400f, and it performs well scanning. The problem it shares with the 9000f is the two little flat pieces of plastic that hold the negative during scanning the negative. If you lose or break those little cheesy pieces of plastic, you are Esso L, my friend. Look at the photos of the machine here on the Amazon website and you'll see what I mean.
Excerpt: J'ai quand même scanné, photos, diapos et negatifs. 2 mois après l'achat, je reçois des messages avec des codes d'erreurs; "le scanner est soit disant debranché ou le cable usb n'est pas relié à l'ordi,...". Je desinstalle tout & réinstalle tout. Je scanne à peine 2 films de 36 poses, puis pareil ! Impossible de scanner ! Je change de port usb. Rien à faire. Je le branche ensuite sur mon autre ordinateur. J'ai scanné 30 photos en basse resolution.
