Summary: An extremely disappointing product; misleading advertisement
Review: I would have given zero star in this rating - but the minimum is 1 star. Anyways! I bought this scanner without checking users review because I was so confidence with the quality of HP products - I've used some and was pleased with them. But this one product turned out to be a great disappointment! I really should have checked users review first; I regretted buying this scanner. Vertical banding always appear whenever I scan something that are: not bright/white colored, not 100% flat against the scanner glass - even something like a page of a thin magazine. This is a fatal, unforgiveable flaw in a scanner - especially at this price. What good is a scanner when the only thing it can scan well is a single sheet of paper with white background - it can't even scan a page of a thin book or magazine well. Banding always appears. And what a misleading advert they give on the brochure: that this scanner is capable of scanning "books on the bookshelf and paintings on the wall". I tried both, and the results were just black blurry things... I contacted HP customer support, and their answer was that the thing to be scanned has to be totally flat against the scanner glass. This is ridiculous; how people are supposed to scan books on the bookshelf or a painting on the wall if those things have to be flat against the scanner glass. So, if you're looking for a good quality scanner, better look for other products. This one looks cool, but doesn't deliver at all. Plus, it's more expensive than other products with similar specs.

Summary: Good looks but no brains
Review: I've had fantastic experience with hp printers and expected no less from this hp scanner. But my computer with the most current drivers, WinXP Pro, and 1 GB of RAM can only identify it as "unknown device." I have tried everything from the hp website and scoured the net for info. This is not an isolated incident because hp has quite a few documents purporting to help owners troubleshoot this very same problem. Tech support implied that blame lay with the Intel chipset ("we've been having problems with their latest...") and said that a USB bus they're sending would solve my problem. Just what I want, more wires. Well, it's been almost two weeks--no bus has yet arrived. I'm disappointed to say the least. Still, it looks pretty just sitting there doing nothing.

Summary: Great design, terrible execution - avoid at all costs
Review: If I could give this zero stars, I would.
I bought a 4670 in December, and immediately noticed the banding/striping problem. Unfortunately, I hadn't yet seen reviews mentioning it, so I assumed it was just my scanner. (Do a Google search for "scanjet 4670 stripes" and you'll find the reviews I missed.)
I contacted HP, and to make a VERY long story short, SEVEN scanners later I have yet to get one that doesn't have this problem. After the seventh one, HP gave up on replacing it, and is buying back the scanner from me. (They also offered to upgrade me to another model, but I have had enough of HP.)
If you aren't sure whether or not your 4670 has this problem, here's a very simple test: get a piece of aluminum foil, and place it dull-side-up on a flat surface. Be sure it is as smooth as possible. Place your scanner on it, and make a color scan. (This also works with dark gray paper or cardboard, but the problem shows up most vivdly on the foil.)
If your scanner has this problem - get a refund. If you can't get a refund from where you bought it, then go after HP until they offer to buy yours back. Even if it takes a couple of months and a half-dozen replacements, don't let HP off the hook with this lemon!
It's a real shame that this scanner is completely useless, because the concept of the design is brilliant. But don't be fooled by looks - until HP publicly acknowledges the problem and fixes it, you must assume that all 4670s are duds. Even after all of my time on the phone with tech support, they never admitted that this is a design flaw that affects all 4670s, but rather dismissed it as an isolated issue. HP should initiate a product recall, fix the problem, or give customers a refund.

Summary: Light and dark bands through the scans
Review: If you carefully inspect a scan of a photograph, you will notice light and dark bands organized horizontally through your image. I tried two separate scanners, three computers with three different operating systems, and installed a USB 2.0 high-speed adapter, and still had a flawed image. HP tech support suggested several procedures, and nothing worked. I paid my own computer consultant to work on it, in case I'd missed something. I love the scanner, but I'm returning it. Clearly, the product has some electronic flaw. Don't waste your time.

Summary: I took a chance despite bad reviews
Review: In spite of the negative publicity with the "banding" issues other consumers have experienced, I really wanted to try this unit for a number of reasons, including the small footprint and the unique versatility of the scanner. I'm running a Macintosh Powerbook with the latest system OS 10.3.7. I can't speak to it's use under Windows XP/2000/ME, but under a Mac this scanner works flawlessly. I couldn't be happier, and I'm glad I took the chance. Overall scan time isn't blazingly fast - on par with previous Acer and Canon scanners I've used in the past. Quality of scans, ease of use, and ingenuity in design make up for the slow warm-up and scan times in my opinion, however.

Summary: SLOW at high resolution
Review: It is so slow when scanning at 600dpi or more and if you look very carefully you can find the color has a certain white and black patten because the scanner scanner the same place twice at higher resolution.
I won't suggest anyone to buy this one and the 2 stars is for the style.

Summary: Nice - if you need something for your kids show-n-tell class
Review: Let me just say this is the worst piece of technology I've played with in some time. I work in IT and purchased one of these because I love new technology and design ideas. I was replacing an older USB scanner, but one thing the 4670/4600 would not do, is DO NICE SCANS! Kind of amazing, eh? Try it for yourself. If you have this model, scan in a night-time or darker photo...a black piece of paper...anything that isn't bright (like a B&W document). Then, zoom in and look at the scan quality. You'll see bands of lighter/darker lines and if your item had lines or graphics, the same place you see these light/dark bands of light, you'll also see the lines don't match up 100%. It's distorted. I was scanning in cartoon art, and it looked like someone was drawing on a fault line during an earthquake. Someone else noted the light/dark bands in their review. I spoke with HP for close to an hour and got a replacement - same problem. Tried it on 3 systems, two different operating systems. After reading other reviews on this, I know I just didn't get 2 bad units. Serious flaw here folks. My older USB scanner never had this, and if you are planning on doing anything beyond scanning in documents, think twice on the 4600 series scanjets.

Summary: Useless
Review: Looks nice, but took me 2 hours with HP tech service to find out that it didn't like my USB 2.0 connector on the motherboard. Apparently this is a common problem and they sent me a usb 2.0 hub to use.
Now that it's "working". It's unpredictable. Sometimes I'll scan multiple images without a hitch. Other days, I'm happy if I can scan 1-2 pages before crashing and having to reboot to continue scanning.
I expected better from HP. When are software and hardware manufacturers going to learn that end users want to use their products and not spend hours to set them up.

Summary: WORST EVER - A ZERO RATING
Review: Scanjet 4670 - Don't listen to anyone who says this scanner is worth using at all. What is the purpose of having a scanner that scans alternating light and dark bands through the image. HP has sent me three so far and I will be speaking with a Manager after they get back to me in 3 to 5 business days. I have been in Design for over twelve years and never have like HP much but when I wanted to get an inexpensive scanner I thought it would be OK? WRONG! Never will I buy anything HP again. Maybe I just expect my images to be absent of stripping, silly me!
I guess if you want to scan in a blank piece of white paper or very pale images you might like this scanner?

Summary: Great human interface, awful scanner
Review: The mission: archive old family photos before my lil' daughter tears them up.
The obstacle: very little desk space
The solution: not this. First, the USB interface is far sub-par. Check HP's troubleshooting on their web site; their solutions to communication problems range from "use a powered USB hub" to "never use a USB hub." Very helpful. As I'm writing right now I'm hearing the USB interface bob up and down as it tries to connect with the scanner. Not working. Plus not only can you not use a hub (I tried a D-Link USB2.0 4 port), you can't connect even to the same USB bus. So unless you've got a spare USB header free from your motherboard, you probably can't connect at all (Amendment: After several hours I discovered the problem - for me, the scanner had to be on a powered hub but my Logitech USB mouse could not coexist on the same hub. Now things appear to be working since the scanner is on the hub all by itself and the mouse has been plugged directly into the workstation. Still a bad USB implementation, tho). Image quality is so-so. Not the greatest... flesh tones are too warm. I used Photoshop, WinXP's Scanner Wizard and HP's prepackaged software - the best results being the TWAIN driver in Photoshop. Speaking of which, the bundled software was harsh to use. For some reason it decided I wanted to scan my text documents as embedded objects in RTF's. Wha? The HP software was not good at all. The actual TWAIN Photo & Imaging Directory scanning interface was fine however - just the actually document management software was clunky. Beautiful looking and a real space saver, but if it doesn't work well then it's just an expensive window.
