Pros: well packaged and easy to install and set up. was able to determine file location for saving documents easily.
Cons: ADF (automatic document feeder) does not work. Jams easily. We could not get further than one sheet, did not scan two sided. Jammed every time it tried to scn second side. Essentially useless for desired purpose. I am returning today
Summary: I'm becoming convinced that anytime a company like HP puts something on sale at Costco it's because the item is flawed. That's putting it lightly with this total piece of junk. From the moment you open the box and realize there are NO INSTRUCTIONS, it's an aggravating endeavor. But, being the semi-techie that I am, not a biggie. So I had it up and running and scanning quite quickly. The joy lasted about 15 minutes.
Pros: it worked for 20 minutes
Cons: it stopped working after 20 minutes no instructions error messages pop up constantly
Summary: HP Scanjet 5590 Short life. Brought one in December 2010, SOLD AS USED, tested working machine. 50 percent of it. Right Away problem with the DOC FEEDER, ADF. Brought new power cord, CD drivers and downloaded updated software. Went to HP for help, They just tried to sell me cleaning cloths for approx. $40.00 or new rollers or new something or other for hundreds of dollars more. Cost more to fix than I paid for it. Scanner still not working.
Excerpt: Needed scanner with a document feeder, and paid a premium for this scanner. Document feeder constantly jammed, paper was difficult to remove without tearing, and difficult to fish out of the works. I eventually resorted to feeding in sheets one by one by hand. Software was powerful, but difficult to master, and often got in the way of simple scan jobs. In addition, the lamp failed more quickly then with other scanners.
Excerpt: We use this product in our law office for legal document scans. It worked really well for about 8 months. Then the Automatic Document Feeder stopped working and a week later, the software went kaput. A very slow and unpredictable machine.
