Legal Disclaimers
- 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 March 2024.
- 2. Individual cartridges estimate based on print yields of an included or replacement set of black and color ink bottles as compared to Epson standard-capacity ink cartridges for similarly featured printers as of March 2024.
- 3. 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

Q: QuestionDoes this printer have 2-sided scanning through the ADF?(8 answers)
A: AnswerThe question was "will this scanner scan both sides using its automatic document feeder." Just because it has an ADF and can p-r-i-n-t two-sided, does not mean it will SCAN both sides of a document in ADF mode. I got burned on this issue with the ET-3760 which I was led to believe did double sided scanning thru its ADF and it DOES NOT.Answered by GaryC
Q: QuestionWhat is the difference between the ET-3850 and the ET-2850?(2 answers)
A: AnswerHello TC. The main difference between both printers is that the ET-3850 includes an auto document feeder. This allows you to load up to 30 plain paper pages and scan multi-page documents more efficiently. Regards, Kevin - The Epson Team.Answered by Epson
- A: AnswerHello gottaprintnow. The ET-3850 has a low ink alert system, so you want to try and refill the ink tanks once the ink is below the lower line. This will help maintain the accuracy of the system to help read levels correctly. You want to avoid waiting until the tank is empty as continued usage could damage the product. Regards, Kevin - The Epson Team.
Answered by Epson
- A: AnswerYes you can! This printer comes with a printer USB, ethernet, and power sockets as shown in the photos.
Answered by RogueWave
- A: AnswerThe photo printing quality is excellent - not quite as good as a dedicated photo printer, but very close. Attached is a sample that I printed.
Answered by JimC
- A: AnswerYes, you are correct, if maximum resolution is selected. But, it may not always be noticeably sharper to print in 5760 x 1440 vs 4800 x 1200. This kind of differential tends to be more noticeable with photos and graphics. But, this printer is NOT a photo printer. It's also NOT an enhanced paper-size printer. So, with standard size text, in my opinion, the maximum resolution differences with the two printers, ET-3850 and ET-2850 may not be appreciable to the naked eye.

Great for homeschooling and household office
I purchased the Epson EcoTank ET-3850 printer to replace one that used ink very fast. A few years ago, I purchased a Canon for $20 on Black Friday at another store. That $20 printer cost me $50-60 in ink every 150 pages. So far with the Epson, I have printed about 100 pages with very little ink missing from the tanks. I like being able to see the ink in the tanks. I always wondered if the other ink cartridges actually contained much ink. I only use the printer for homeschooling and household office printing. The printer is perfect for my purposes. It is very fast compared to my old printer and also pretty quiet compared to the other, though not as quiet as some others might like. I was able to print double sided with the top copy master feed. I liked this feature, but I am not able to double side print when sending documents from my computer. If there were a way to do this, I would love it. Maybe I just need to figure out how to use the printer, but this is not as important to me as might be to some. I just print out the documents single sided then use the copy feature to double side print. The printer makes it easy. So far, I have used cardstock as well a
