Summary: FAR to slow!
Review: I waited 10 minutes for a scan of a bussines card in 600 dpi!!
300 dpi scans fine but anything higher takes to long, with a bigger scan you can wait more than 30 minutes where my Epson takes 4...

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: Seriously flawed
Review: I loved the design of this scanner and needed to be able to scan both large items and negatives. Unfortunately, the scanner doesn't work properly. Negatives come out greenish yellow where there should be blue; light colored pictures come out with banding -- dark and light bands across the picture. Tech support seemed very aware of both problems and told me to return the scanner to the store where I bought it. Both phone and email support did not indicate that there was any fix for these problems. Too bad, as I really wanted this scanner. I hope HP fixes the problem; if they do, I'll buy it again.

Summary: Great design. Unsatisfactory execution.
Review: I am a long-time HP printer and scanner user, and I really liked the design of this scanner. Besides having a knock-out appearance, I loved that you could fold it up and put it on a shelf. However, this scanner did not meet my needs and I ended up returning it.I bought it for two applications: scanning documents and converting them to text with OCR, and scanning old family slides. This is NOT the scanner to buy for either application. The cheap OCR software included with the scanner is virtually useless. My typewritten documents came out hopelessly garbled - it would have taken more time to correct the mistakes that it would have to re-type them from scratch. If you plan to use this scanner for documents, plan to buy a better OCR program to go with it. As for scanning slides, the first unit I bought had a loose connection from the scanner to the slide attachment, and I had to exchange it. The second unit worked, but the scan quality was just not what I was hoping for. I returned the HP and bought an Epson 3170 instead. It comes with a far superior OCR program, and Photoshop Elements to boot. I'm not sure the slide scanning is much, if any better. Could be I'm just asking too much from a flatbed scanner...

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: a beautiful piece of junk
Review: another reviewer said don't use this scanner for anything other than docs - mine won't even do docs consistently - more than one page is asking too much - even if the preview indicates it scanned the entire page, when you go back and check the pdf file, it is missing pieces of the page - and getting the image at all is hit or miss - I've had 8-10 scans in a row show up with nothing but a black screen - UNBELIEVABLE!!!

Summary: Nice to look at, poor scan quality
Review: I have an HP Scanjet 4C that has been a workhorse for the past 4-5 years (It still works, but my new Macintosh doesn't support SCSI devices). So, in deciding on a purchase I chose HP again out of loyalty. Set-up on the 4670 was easy, the software acceptable (typical of HPs), and the scanner itself was beautiful. Unfortunately all images that I scanned were plagued with 1/2" tall bands of light and dark areas. I found no way to remedy this and was forced to return the scanner for a refund.

Summary: HP 4670 Scanner
Review: I purchased this scanner for the flexability that the form factor offered, but I was frustrated by several aspects of the design, documentation and software. 1. The scanner has a long USB cable that pulls laterally from the USB prt on your PC. If you leave it connected for any length of time or accidenty pull on the cable the port is sure to be damaged. 2. the software is junk. It's hard to figure out, crashes and gives less than perfect results. To save a scan you have to click several times and rename the file completly (it does not remember the last file name and allow to you append a number to it, you have to reenter the name completly every time.) So doing lots of scans quickly becomes a chore. The dark areas of scans have scan lines through them. 3. There is no manual. Well, there is a manual, but it's worthless. Nothing explains how to use settings and how to change them. The Arcsoft panoramic software crashes when trying to save and takes a huge amount of time to stitch high res large files.

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: Better than Expected
Review: This scanner I've found turned out to work much better than expected. I needed a replacement when I put my printer/scanner on a network interface and lost it's scanning abilities. I gave this one a try, because of the small space it takes up. But, I was wary of the negative reviews it's been receiving. I got it and installed it. I didn't have any problems with Windows XP. Properly installed with administrator rights, and not making the mistake of hooking up the printer before installing the software, I didn't have any problems with the computer not recognizing the scanner. Admittedly I don't use the HP software, but my own 3rd party software. The software isn't really that good. Scan quality is good. The first scan does take a long time, but subsequent scans are very fast in comparison. The negative and slide scanner does turn out good scans, if you're using the default quality settings of 300dpi. It's better on higher settings, but takes forever to scan. Overall, an excellent buy.
