    Rated 1 out of 5 by from Waste of money I wish I had not bought this machine. Frustration almost every time I tried to print something. Print quality is fine. For my purposes, ET-2800 is far superior overall for a home user.

    Rated 1 out of 5 by from Ink Guzzler 3820 I am totally disappointed in this unit and will be returning it. I've tried to print 200 copies of a 2 page newsletter. Some pictures and have now gone through two XL packs and the package on ink that came with the unit. I just bought this at Black Friday. The XL packs are $70 each (approximately). Do the math.

    Rated 1 out of 5 by from worst printer I ever owned This printer has been nothing but trouble since the first day I bought it I have been calling Epson so many times they trouble shoot and it works for a few weeks then I have to call again. They refuse to replace it they are waiting for warranty to expire se that they can tell me it's no longer their problem.

    Rated 4 out of 5 by from Good for the price The Printer portion has been working great. Have had over a year now. The ADF, during scanning multiple pages, does not always grab every page. This is a pain! The scans are also not as crisp and clear as I would like. I do not have to scan that often so not a big problem for me. The setup and use of the printer was very easy as is downloads of software updates.

    Rated 5 out of 5 by from Just Right Features For The Money This is my second Epson printer coming from a WorkForce 2750 and I have been pleased with its performance and reliability. So when it came time to replace it I began my research comparing the top 4 brands in this printer class, I was quite surprised with my findings, with the Epson printing the highest quality prints with laser-like sharpness and doing so quite quickly too, only one other printer got anywhere near the quality. I needed something network ready that I could connect all my computers and devices to, I've already had the pleasure of having Epson Connect from the old printer and have iEpson app on my phone where I'm able to print from a remote location, which works very well, so finding that Epson WorkForce series printers seem to fit my needs, made shopping easier, I was originally looking at the WorkForce 2960 but this one was on sale for less than it and especially given the 18,000-page duty cycle and that this can print about 75% more black and about 60% more color pages than it made it seem a no-brainer. The touchscreen menu is easy to navigate and has a customization that allows for a different color scheme for the background, it made setup a little easier, though I'd have admit it would be appreciated if the screen was a tad larger, about 3 inches instead of 2.7". The FAX performance is amazing, most in this class offer the same speed and yet it's notably faster sending FAXES. Most of my copying and scanning I'm using the flatbed screen as opposed to the ADF, which is probably why I've never had an issue with any paper jams, the exception might be when I'm doing something with legal-sized paper. The print quality is excellent on everything I've printed so far, it also does it quietly, should mention that there's a setting to put it in quiet mode and it works well. For the most part this is a good value for my level of printing, however, the ink consumption is a little higher than the others, the ones that I compared, there comprise was to reduce sharpness to save ink except for the one which came close to this one and it also uses a little more ink, so the bottom line to get that high-quality print, it's got to use a little more ink. I have to commend Epson for an outstanding job in packaging this printer, nothing is going to move in transport, took several minutes to get through all the blue tape everywhere but the package also includes a CD and power cord, so if you desire to connect phone line, ethernet or USB, you will have to provide your own cables. The paper tray can accommodate 250 sheets, the paper tray is at the bottom, if you happen to have any soft or bulky on your surface, it may interfere with how the tray opens, this is where I'd value it if Epson had place 1/2 rubber feet on the bottom but not a serious issue. In my closing, this is an exceptional home office printer that's ideal for those who print 100 sheets a week or less, if you're printing more than that it would be wise to consider a printer with larger capacity ink cartridges in order to keep your cost per sheet down. To maximize your ink performance it's also ideal to have the proper paper just for inkjet printers, I learned the hard way on my old printer, poor quality paper uses more ink. When you go to purchase this printer, it does come with ink cartridges but only the starter variety which is only about 25-30% of a normal cartridge, so I'd recommend you purchase the 888 cartridges this printer uses at the same time. Overall I'm very satisfied with this Epson printer and would recommend it to others with similar use as mine

    Rated 4 out of 5 by from WorkForce Pro WF-3820 Wireless All-In-In-One-Printer For the most part it is an excellent printer. The only problems I have is the paper keeps jamming up. Gets to be very frustrating. Also, maybe its's me but I can't print out just a half sheet when I need to print a shipping label. With the Cannon printer I can do that but for some reason my laptop doesn't want to communicate with the Cannon. Such is life. Maybe I'll figure out this Epson!
