Summary: The fact that this scanner is not compatible with Image Capture for transparent documents, was reason for me to return the scanner to the shop. The provided canon software looks out-of-date and is not as flexible and professional as you'd expect from this scanner. The software is by far not sufficient for making hiqh-quality scans from negatives. I also wouldn't recommend this scanner for it's hardware design. The machine has a cheap plastic appearance.
Summary: I have had a few recent lemons (none Canon) this one works great and has enough bells and whistles to fit all my needs. Very pleased so far. I have a few functions left to test out but I have faith!
Summary: Great tool for scanning images into photo shop. I love everything about this item EXCEPT the "Instructions". IMHO the instructions are probably wonderful for someone who already knows how to set the unit up and operate it. For me, (Mister Ignorant,) they are pretty much worthless. After giving up on the digital manual, I simply went tp photoshop and let the software guide my footsteps.
Conclusion: 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.
