Break the strangle hold that you H_ printer has on you.

I bought this printer a year ago. It has been one of the best purchases that I've made in years. I've used it almost everyday for a year and still have plenty of ink left in the tanks. My former H_ printer was locked out on me because I used aftermarket ink. It would stop working whenever H_ decided to coerce me into buying their ink. I stopped fighting them and gave in. Signed up for automatic H_ ink replacements. After accumulating several cartridges that weren't being used, I stop the auto replacement. Then when I finally needed to use the ink cartridge I purchase under H_ ink replacement program, they didn't work, because I was no longer enrolled in their ink replacement program. Ink that I bought under this program was locked out because I quit the program. If that's not extortion what is. I haven't used one four letter word in regards to this Epson printer. I can't say the same for my last printer.

Terrible all around. You've been warned.

Junk - jams when trying to make copies or scan items. Also double side copying works one minute and not the next. Shame on epson?all this thing can actually do decently is print. What a joke. Will never buy another epson product.

ET3850 experience is not good!

Epson ET3850 will not stay connected to our network, constant disconnect errors requiring multiple reboots of printer and network each day. This is not a user error as it has been well documented by many Epson ET3850 users.

Terrible Epson Online Store

I ordered this printer from Epson and their service was so unhelpful that I never received the printer, yet they are charging me for it (I filed a stop payment with my credit card company), and just today Epson charged my card with the shipping of the unshipped printer (I have also contested that charge). Even though the printer is still in their warehouse, I have cancelled the order; but doesn't seem to make a difference. I will never again order anything through Epson's website. Their service is terrible.

Not a good printer

I have had so many issues with this printer. Sometimes it works, sometimes it does not. I turn it off and unplug it, then turn it back on and sometimes it works, but not always. I don't use it much but when I need to, it's not dependable.

I am constantly having connectivity issues with this printer. Makes me insane and is such a waste of my time. I am going to see if Costco will take it back. The only thing I like about this printer are the ink bottles

There are no good printers any more.

When I purchased this printer because I had trouble with cartridges drying up on me and I was told that this ink system would work better. After not pri ti g for a few weeks the ink levels showed full but it would not print even after cleanings.

Worst printer ever

Do NOT buy this printer. The paper jams nearly every time I want to print, rendering it essentially useless. I have tried various types of printer paper, it jams with all of them. My printer isn't even a year old and soon I will be throwing it out (not even donating it, I wouldn't inflict this printer on anyone else) and purchasing a new printer. It will not be an Epson, I will NEVER buy another Epson printer.

Good hardware, bad software

product works fine except for 2 aspects: set up is poorly designed. At one point asks for a password, which i never set up and doesnt offer the ability at that point to create a password. Connectivity to wifi is horrible. sometimes it works, sometimes not. Usually it says Printer is offline, default.

Would Not Recommend

Would NOT recommend this printer/scanner at all. It's AWFUL. I can't get anything scanned to my computer, no matter what or how I try to scan.... the printing feature is so slow you will think it isn't working only to find an hour later something has printed. Take your money elsewhere.... this thing is a piece of junk.

Zero WI-FI connection

We purchased this model at Sam's Club in March. It was to replace a HP model with cartridges. We wanted to try the new Super-tank technology to save on ink. I did not set it up until late May, or attempted to set it up. We have spent hours and hours to try to connect to our wireless network. It won't connect to our wireless router period! Even connecting to our I-Phones and I-Pod is troublesome. It will not stay connect. We looked at the reviews and found this is way too common. We tried using the link that customer service provided on the customers who experienced the same issue and no luck. We will probably just give it away and bite the bullet. I will go back to HP and try their tank system technology. I do not recommend this product. I strongly recommend that you do not take a chance on Epson. This product is junk and that is putting it mildly.

ET-3850 - Insufficient instructions on Epson Support site

I bought this printer ET-3850 in Costco for home use. Box does not include software. My laptop is Acer with windows 11 Home version. Also bought in Costco. Both are new hardware ( Epson Printer and Acer Laptop)Unfortunately, Printer scan function does not work on my Acer laptop. Unfortunately, there is not much online help. It has been more than 2 days since I have been trying. Will try one more day and there is no solution, I will return this printer. This is my first Epson printer. Instructions are very limited and not helpful.

Surprise

I bought two of these printers for the house in the past last month. The install whet very smoothly and have had no problems in normal computer to printer operations. One of the printers is setup for WIFI communications and the other via USB. Today my wife opined about printing from her phone and iPad, so looked into it and it seemed to be straight forward. I down loaded the app and low and behold I discovered I had to pay weekly or monthly to utilize this function of my PC. Isn't it a bit callous on Epson's part to charge extra for built in functionality?

They don't stand by their products or warranty

Was good for a while, then non-stop paper jams. I called their support and they sent me a replacement, but the replacement they sent was defective from the start, it just wasted a bunch of my time and caused a lot of stress. They refused to send me another replacement. Terrible customer service, they don't stand by their products.

I bought this printer about 2 years ago and love it. Have not had to add ink - black at about 20% remaining and all colors at 50%. With an ink jet I was spending $200/year. Zero problems!

Good printer for me..

I purchased a Refurb unit off of Amazon in May of 2024 and honestly, it's been great for me, so it's kind of crazy seeing all of the bad reviews, I must have just gotten lucky.. It's been the best printer I've had so far with only one feeding hiccup to date. I've printed quite a few photos and of course documents and such.. Hopefully it stays that way

Not happy

Less than 2 months old and since day one it doesn't print the colors on the screen, no matter how many cleaning cycles and alignments I do. So sad. Something has changed. I had an epson for 5+ years and was great. This new one-horrible and it's same model. So drivers have changed I assume. I tried the downloading and installing. Even swapped for more expensive epson and nope same problem.

Terrible product

In summer 2022, I ordered the ET-3850-SE printer. It was a little beyond our price range, but the reviews were very good, and I wanted to invest in something that would work well and last. By spring 2023, the wifi was no longer working consistently, which meant we could only print some of the time. I finally gave up and called customer service in fall of 2023. I sat on the phone with them for two hours one day while they did troubleshooting and then ultimately decided that the wifi problem was due to a common issue with these printers, and they said they would replace our printer with a refurbished model, which they did. Within six months, the wifi again would not work. There was a period of about a year when I could get it to work if I kept turning the printer on and off, removing and replacing the cord, etc. As you can imagine, this feels like an incredible waste of time when I have paid for a printer and just want it to print something. Sometimes we would get it to work, and sometimes we would just give up. About five months ago, the wifi stopped working altogether. No matter what I do, I cannot get it to work. I have now invested in a printer cable and iphone adapter which worked a couple of times, but now the printer will no longer communicate. In total, I purchased a printer, extra ink (because I was planning to use this printer long enough to need it), a printer cord, and an iphone adapter cord. Out of 2.5 years of having this printer, there was only a little over a year that it actually worked properly. I know that I am outside of the warranty period at this point, but I am incredibly disappointed and will never buy another Epson printer.

Great printer at first, 4 months later it 's a headache

Worked so well for about 4 months. Then, stopped recognizing each computer randomly. Now, the printer will not print unless I plug directly into the printer, only then will it acknowledge my computer. No other computers can print. The scanner is no longer recognized either. Get error messages that the ET3850 is "busy" or "offline" or communication error. Tried many things to correct it. Avoid this printer. Unreliable and unpredictable.

Great 'til it doesn't like the Wi-Fi anymore. Then nightmare

Bought this in October. It is our second ecotank, I bought it because I liked the last but it was a lower model so I upgraded and passed the other to our daughter. That being said--for the last several months printing from my computer has been a nightmare. It keeps losing Wi-Fi connection for no discernable reason (computer, tablets, etc, are all fine and dandy, just this printer that isn't on speaking terms any more with the router). Turn off, unplug, plug in, turn on and MMMAAAYYYBBBEEE it will print ONE document for us before stopping. We use this for our product labels, for legal documents, even for our homeschooling. Except now we don't. So. Great printer--until it decides it wants a divorce from your wifi. Then it's irreconcilable differences.

Good printer, overall

I had been getting by on a $50 inkjet printer, and often spent more than the cost of the printer whenever I bought an XL B&W and XL color refill cartridge together. So when I saw this on sale at Costco, marked down $50, I did not hesitate. Thus, it was a classic impulse buy, with zero due diligence performed. PROS: It has been reliable, and the ink bottles last quite a while before they need to be refilled. Double-sided printing has worked well. Print quality is excellent, maybe a 9 on a 10-point scale. CONS: Scanning is slow, printing is slow, and even copying is slow. The touch-menu is not as intuitive as it could be, and copying multi page documents via the automatic document feeder is especially confusing. UNKNOWN: I haven't bothered to try WiFi printing, since the printer and computer are always in the same place. CONCLUSION: I have not had to experience the horrors of Epson customer non-support that others have mentioned, and thus far it has been reliable. I wish I had done some market research before buying it, but all in all, I don't regret this purchase.

Absolute Workhorse!

I really don't understand where the complaints are coming from? I've had this printer (bought from Costco) over two years. My print count is around 8000, and I have not had a single issue. I have used the scanner hundreds of times, as well as the document feeder with no problems what-so-ever. During my professional years (37) I have used dozens of desktop inkjets and color lasers - HP, Canon, Epson. For the price, you cannot beat this printer - it's a workhorse!

Great for ADF printer and setup is a breeze with the APP

By IrishChippy

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 pri...
