Rated 1 out of 5 by from Doesn't work I have owned for about 2 years. It will NOT scan when I push the scan button. It just stopped working. I had to delete and add the scanner back. Still having problems with scanner.

Rated 4 out of 5 by from Love It I have been using my Epson ES-400 scanner in my home office for several years. I recently closed my home office and moved my scanner with me to my new job. It is the best piece of office equipment I have ever bought.

Rated 5 out of 5 by from Great document scanner with a small footprint I've had this little workhorse for at least a couple of years. Easy to set up, takes up very little desk space and it's worked flawlessly. I'd buy one again in a heartbeat.

Rated 4 out of 5 by from Quick, Fast, Easy Editable Scanner I have enjoyed a similar one at work of another brand, but was more expense. This is a third of the price and does the same exact thing and very compact! I love it! I use it to keep all my file remote instead of a file cabinet filled of papers. My only downside to these scanners, is when they think there is an error of a double scan. So if you want to tape two or more receipts to one paper, or carbon copy is scanned, it thinks there is an error of duplicated accidental scan. This is not the case, this also happened on the more expense brand at work. It is worth every penny. I have scanned over 500+ sheets and have had it for a year, going strong! My only suggestion is when scanning receipts, to make sure the sides align close the receipts, if not it will bunch of in the rollers. I expect this to last a long time. I have had an Epson printer that lasted forever, but upon being so out dated, I upgraded. Epson is a wonderful brand I have not had any issues with.

Rated 4 out of 5 by from Good purchase This scanner is definitely a good one. It is high-quality and compact; it was also very easy to set up and use. It works very well for our small office! There are only two things that I would change. First, I am not able to have anything taped to the back of a document: if something is, it will not go through because it detects a double-feed. (It is sometimes nice to retain original, handwritten notes.) Second, the scanning software had a small quirk. When deleting unnecessary pages, the program takes you back to the first scanned page after clicking the delete button, rather than keeping its place in the document and allowing you to make a new selection. This is just a bit frustrating when there are a few hundred pages.

Rated 4 out of 5 by from General Observations I purchased my Workforce ES-400 over a year ago and i am generally pleased with it. It is easy to operate once you get the hang of it. The user manual leaves a lot to be desired and never quite answers my questions. Support quickly responded to my questions and assisted in solving the few problems I have had. Biggest limitation is its capacity. I do a lot of 150-175 page scans for uploading documents and have to divide them up into 50 page parts and upload each part. Occasionally the ES-400 just stops working. So far following instructions from support and rebooting solved problem

Rated 4 out of 5 by from Great machine Bought two months ago, does exactly as advertised. Would have given five stars except it had stopped working, tried to download free updates but was convinced online to purchase new programming that we later discovered was the exact same that came with the machine. Epson refused to reimburse the purchase, so we're stuck with a duplicate program we don't need and out the cost as well.

Rated 5 out of 5 by from Generally fine, sometimes squeals I've had this scanner/product for months now and have put a lot of paper through it. However, from time to time, the wheels make a noticeable squealing noise that I have yet to determine how to solve. This issue pops up from time to time, and is not constant, though it is odd. Maybe it is the throughput? Or, well, maybe there is a better way to design the auto-feed mechanism. I don't know. Generally, though, I have been quite satisfied with it. I like this scanner and it fulfills the purpose I got it for. As such, I will not hold this against the rating. :-)
