Rated 4 out of 5 by from So far, so good (8 days) Our faithful 5+ year old Epson WF3520 locked up on us and rather than pursuing the problem we decided to buy a new printer from Epson. We were impressed with the idea of refilling the cartridges ourselves and bought the ET-3850. Filling the cartridges is a breeze and we have have not had any printing issues so far. The reason I gave 4 stars is due to the construction when compared with the WF-3520. WF felt solid in comparison to the flimsy feeling of the ET model.

Rated 5 out of 5 by from Nice Printer I was an Epson ET-2760 and didn't like it because there wasn't an auto feed. It was a pain to make color copies if more than one page plus it was extremely slow. I still have the printer but not using anymore since I got the ET-3850. It is great and is so much faster printing. I have another black & white laser printer that I use for scanning so I have not tried scanning on my new printer. I do not use the fax on either of my printers. The Eco Tank is wonderful. I had my 1st Epson for over 2 years and it still has ink in it. So much more economical.

Rated 2 out of 5 by from Used this printer one day, I'm returning it The very first page I printed with this printer left a streak of black ink across the page. This happens about 20% of the time. I print a lot of labels and business cards that have tight tolerances. This printer does not consistently print in the same place. I couldn't even print one page of business cards. The colors produced are FAR from matching my computer screen which I never had to deal with on other printers. I printed areas with black that had yellow halos. Now I'm getting a white line through my print and alignment seems to be off (even after running the alignment procedure). What prompted me to write the review was printing brochures and 2 of 3 had black ink streaks/drips across the page. I'm done with this thing and it only took me one day and less than 20 pages to figure it out. In defense of this thing, I have printed a couple pages of text and it seems to do well on plain paper. So this may work for you if you don't need tight tolerances or anything other than plain paper. I have not seen any of these issues with my 10 year old Canon. But It finally had an unrepairable error. I guess my search continues.

Rated 2 out of 5 by from It's alright not happy with compatibility and downloads My boss purchased the printer to replace our HP. Not thrilled about the transition and ink filling process. It's a little time consuming, the printer comes w/ a disc drive for download and our office computers are upgraded w/out no CD drive. The scanning feature is odd, try to scan directly to the computer but now I have to download another app. I've downloaded 3 drivers so far to use different features.

Rated 1 out of 5 by from Lengthy Setup/Poor Instructions During set up I registered the product as requested. Did not register so wasted time doing that. Then it asked for password to continue setup but never asked to create one at any time. Said to use Serial Number from the back of the printer. No serial number on the bak of the printer. When loading paper it asks the size of the paper. I selected 8 1/2 by 11. Hit okay. Next screen asked for size of paper. Selected 8 1/2 by 11 again. Both screens were asking for the size of the paper in the cassette. Hitting OK after selecting the same size on the second screen took me back to the first screen and repeated three times toggling between the two screens. Finally gave up and hit the Home screen. Tried to print from my laptop and all it does is give me an error message that the paper size doesn't match what is in the paper cassette. All the paper in cassette is 8 1/2 by 11 and the screen shows that is the paper size. Still couldn't finish set up with out a pass word or serial number. Turned off the printer and unplugged it. Turned the printer upside down and found the label on the bottom. Of course I'm sure this was great on the ink tanks. Created and account at Epson.com so I could see if they could give me the serial number on the registration. That is when I found out it wasn't even registered. Had to have the serial number to register it and that is why I had to turn it off and turn it upside down. Still can't print the lap top because the cassette has 8 1/2 by 11 paper and the error message says the wrong size paper is in the cassette and needs not the 8 1/2 by 11 that is there but 8 1/2 by 11 that is needed to print. Over three hours of trying to install this printer to print a one page document and still not able to. I could have written it long hand by now wilh less stress.

Rated 2 out of 5 by from Wireless specs not published. Will only work on 2.4ghz wifi Got this for the family at Christmas. We have various things to print in color and this looked to fit the bill. I have over 20 years experience with IT and networking, so setting this up on the home wifi should not have been a problem but it was. The app assisted method is easy enough and straightforward for people that need simplicity. My issue is that no where were the specs published on this device that said it would not connect to a 5Ghz wifi network. Apparently this device is just not capable of that - even after the code updates. I really wouldn't have bought this if I had known this little fact. I finally found a support article, (still not confirming it - but said to combine the 2.4 / 5ghz namespace in order to connect. Not wanting to do this. My home wifi is setup a specific way. I ended up putting it a separate 2.4ghz network that's dedicated for something else, but had no choice. It prints fine. Not liking the extra software this installed on my laptop. All I want is the driver not a whole suite of stuff actively running. Not a problem, I can customize that. I'm just surprised that this new printer can't work over 5Ghz wifi signals. Disappointed that Shaq knew this and still endorsed. I believe he's supposed to be quite well tech informed. Aside from all that, I was impressed with the ink setup. We'll see how long term that goes. It prints and copies just fine.

Rated 2 out of 5 by from Just average printing with poor scanning function The worst part is that the scanner function requires an "excellent" wifi connection. It will not scan without a high level of connectivity. "Good" will not cut it. Otherwise you must go with a LAN / Ethernet connection. Printing is not much better than my old Epson 830, and photo printing is "fair" at best. While the ink tank concept may be economical and eco friendly, it is an expensive average printer.

Rated 5 out of 5 by from Great for ADF printer and setup is a breeze with the APP I bought this new model last month. Installation was so simple, using "Epson Smart Panel' APP, which takes you right through the setup. No-spill ink tanks are great compared to the original Epson printers. Initiation takes about 10 minutes, and then a few more clicks and you are finished. You can then download the software. Epson ScanSmart has a nice fresh interface compared to Epson Scan. The ADF works well, but the paper must not be crinkled on the edges. When using ADF and double sided printing, you need to select paper size (Letter, A4 or Legal). The tray holds up to 250 sheets, which is a bonus for me in my home office. Overall, this new EcoTank ET-3850 is a great home office machine for those who do not need FAX. There is a model ET-4850 that has FAX that has similar features to this

Rated 5 out of 5 by from Excellent printers If economical printing is your first priority, this is for you. You need to have reasonable expectations about everything else. There are printers which are faster, print pictures better, scan faster, etc, you can't have it all at this price. We have five of these in our clinic for everyday printing and a business-grade printer for our scanning and for when we need high-quality color copies.

1 Actual savings and costs will vary considerably based on print tasks, print volumes and usage conditions. Savings and cost per ISO page are based on the cost of replacement ink bottles and the cost of enough standard cartridges to achieve the total page yields of the bottles using the MSRP (USD) and yields for Epson standard-capacity ink cartridges for similarly featured Epson consumer inkjet printers as of May 2021.
2 Part of the ink from the included bottles is used for initial setup; yields are lower than those of replacement ink bottles. Replacement and included ink bottle yields based on the ISO/IEC 24712 pattern with Epson’s methodology. Actual ink yields will vary considerably for reasons including images printed, print settings, temperature and humidity. Yields may be lower when printing infrequently or predominantly with one ink color. All ink colors are used for printing and printer maintenance, and all colors must be available for printing. For more information, visit www.epson.com/inkinfo.
3 Individual cartridges estimate based on print yields of a replacement set of black and color ink bottles as compared to Epson standard-capacity ink cartridges for similarly featured printers as of May 2021.
4 Based on average monthly document print volumes of about 200 pages.
5 See www.epson.com/voice for device compatibility. Epson Connect™ account and voice-activated account registration required.
6 Most features require an Internet connection to the printer, as well as an Internet- and/or email-enabled device. For a list of Epson Connect enabled printers and compatible devices and apps, visit www.epson.com/connect.
7 Requires Epson Smart Panel App download. Data usage fees may apply.
8 12 months of standard limited warranty or 50,000 plain paper sheets (whichever happens first). For an additional 12-month extended service plan (total of 24 months or 50,000 plain paper sheets, whichever happens first), you must register your product and use Epson genuine ink bottles.
