Great fast scanner
I've been VERY pleased with this scanner for the cost VERY good, seems fast and accurate. Cannon seems to contine support for new drivers and software OS, some companies do NOT.

I have had this scanner for 2 years, using it mostly for pdf documents. I had a problem with speed and disfunction as mentioned in a number of the negative reviews. I learned that the cause of the problem was my USB port. When I used my usb extension port the scanner was slow and disfunctional. When I plugged it into my Mac installed port it worked fine. You might explore this yourselves in such cases.

I went to use my scanner and realize it does not do slides.
very well. I need the adaptor for the slides if it comes with one .The adaptor is only for negatives. I was told it was just like the one I had which did slides and was great . That why i went with this one .

Fills the Bill, Perfectly
Small footprint, low profile, big features....this unit beats the others hands down. Running exclusively on USB power, this unit has all of the advanced features. It is the most user-friendly scanner that I have ever used. The hardware and the software are both superb. Canon has a winner with this one!
