Summary: My friend has a 4670 and loved it. So I checked it out and the reviews were not all favorable. A lot of mention of alternating band of dark and light on color scans. I have not noticed this at all.
Summary: I've owned the HP 4670 for nearly 3 years and have very few complaints. I don't understand the bad reviews about banding. I've never had anything like that. I work on a iMac G5, do lots of photo work.
Summary: I was completely satisfied with this scanner. The only problem I had was a software glitch when I upgraded to Explorer 7.0, but that has since been fixed. Unfortunately, as with most peripheral equipment made for previous operating systems, it does not work with Vista.
Summary: Like many reviewers here I had a dead one of these things. HP replaced it without a quibble though and the replacement has been just excellent. I do like the machine itself, though I have to say that the HP bloatware scanner software is really very unpleasant.
Summary: Pretty good for the money. If you are really picky about quality you should get a more professional model - this is economy grade. The versatility of this scanner is awesome since it can be taken off the base and used to scan large items.
Summary: I'm a network administrator (among other things!!) and my boss decided to buy this scanner for my department. I do a LOT of scanning and I don't have any complaints about this scanner. We've had it for about a year without any problems.
Summary: After looking through the other reviews of this product, it's very clear that there was a design flaw early in it's prodcution. However, I bought my unit from Amazon in Januray of 2005 and experienced none of the issues others have. So, maybe the problem has been fixed.
Summary: Not a bad little scanner. I like its appearance, goes nicely with my iMac. The scan quality is very good and I have had no problems using the scanner (I had been concerned after reading some of the reviews). The scanner utility for quick scanning is very nice.
Summary: I have only had my scanner a month, but I have had no problems with it. I do a lot of OCR scanning, and I use both the IRIS softwear that came with the scanner and OmniPage, and both work fine.
Summary: As noted in several other reviews, the 4600 is prone to vertical banding in scans throughout (others have complained of this effect). I ran in to this problem with my 4600. I contacted HP support and they replaced my 4600 with a 4670 for free, and extended the warranty a full year!
