  • Excellent and Innovative printer
    Reviewed by SimpleLiving - September 18, 2021

    [This review was collected as part of a promotion.] This Epson EcoTank printer is excellent, and it is a must-have consumer office machine. Gone are the old spontaneous frequent replacement cartridge. Now anyone can make an economical print in color and high volume. I am an accountant, and I got this printer exclusively for my home office. Printing cost is reasonable that now my wife and two kids use a lot for their virtual school. It is getting plenty of use. Setup and connection take about 20-25 minutes to complete and require careful step-by-step instructions to fill the tanks with ink. I downloaded and used the Epson Smart Panel app for the entire setup (this is optional). Each color bottle is uniquely keyed, which makes it easy and error-free to fill each color tank. The uniquely keyed bottles are an excellent idea to prevent filling a color tank with a wrong color. Filling the tank, one must be careful not to squeeze the refill bottles. After the tanks were all filled, I followed a few more steps and connected the printer to the Wi-Fi. The touch screen responds very well, but the size could be a bit larger for bigger fingers. I like the convenience that I can print and scan from a mobile device. The Epson Smart Panel app has a tone of features on how to print or scan. A unique printing is ID cards; I can print both sides of any ID using the app in two steps. Scanning is fast with either the glass flatbed or the automatic document feeder. So far, I haven’t had any issue with the automatic document feeder. Once you get used to the machine, you will be scanning and printing stacks of documents. The prints come out with vibrant colors, and the blacks are dark enough. This Epson EcoTank printer does its primary purpose very well: to print fast and economically without compromising quality.

  • Workhorse printer, scanner, copier and fax
    Reviewed by MrGadget - September 13, 2021

    [This review was collected as part of a promotion.] For small offices and busy home offices, the new Epson EcoTank SuperTank ET-4850 All-in-One cartridge-free printer is a nice step up from ordinary. Print, copy, scan and fax from this all-in-one, saving big on ink throughout ownership. Here is a sample of its pedigree from Epson: • Unique PrecisionCore Heat-Free Technology™ and Claria® ET pigment black ink produce extremely sharp text – plus impressive color photos and graphics – on virtually any paper type • Built-in Scanner & Copier — High-resolution flatbed scanner and a 2.4" color touchscreen for easy document copying and navigation • Robust Paper Handling — Auto Document Feeder, paper-saving auto 2-sided printing and a 250-sheet paper tray for high productivity • Built-in Scanner & Copier — High-resolution flatbed scanner and a 2.4" color touchscreen for easy document copying and navigation • Modern Connectivity — Features Ethernet and wireless, plus hands-free voice-activated printing. Easily print from your smart device with the intuitive Epson Smart Panel® App What about EcoTank SuperTank? •Innovative Cartridge-Free Printing — High-capacity ink tanks mean no more tiny, expensive ink cartridges; Epson’s exclusive EcoFit® ink bottles make filling easy and worry-free • Dramatic Savings on Replacement Ink — Save up to 90% with replacement ink bottles vs. ink cartridges – that’s enough to print up to 7,500 pages black/6,000 color, equivalent to about 90 individual ink cartridges • Stress-Free Printing — Up to 2 years of ink in the box – and with every replacement ink set – for fewer out of ink frustrations • Zero Cartridge Waste — By using an EcoTank printer, you can help reduce the amount of cartridge waste ending up in landfills • Print speeds up to 15.5 ppm black and 8.5 ppm for color • Scan resolution up to 1200x2400 dpi • Print resolution up to 4800x1200 That’s what Epson tells us. Keep reading for my take! **WHAT’S IN THE BOX** • Epson ET-4850 • Four bottles of Epson ink, with enough ink in the box for up to two years of printing • Power cord • Documentation, including Software CD for Windows, warranty, quick start guide **THE SETUP** There are two ways to set up the printer. For users who already are part of the Epson universe with the Epson SmartPanel app on their phone OR getting the product ready to use, setting up Wi-Fi through the printer’s display without first having the app. Both methods ask the user to follow the prompts either on mobile phone’s screen or on the printer’s 2.4” color touchscreen display. Users are asked at a strategic point to install the ink from the supplied ink bottles, the printer responds to the ink being loaded, and then we are asked to confirm that ink is installed. The printer finishes priming the print mechanism for printing. Load some paper and set the paper size guides in the generous, 250-sheet paper tray. When these basic settings are completed, the Epson can print a test page to confirm its print alignment settings are good and that’s it, ready to go, except for any needed firmware updates. Loading about 100 sheets of plain paper in the tray. I chose to set up the printer for wireless only, though it has an Ethernet port for those who want a hard-wired connection to the network. There is also a standard USB Printer connection for those who want hard-wired connection to a computer. Finally, there is a standard RJ11 phone port with another port, a pass-through for a phone line connection necessary for fax use. The other jack can accommodate a hard wired telephone. None of the requisite cabling is included. Finally, with the printer on Wi-Fi, computers need the software to access the ET-4850 and print, copy, scan and fax. As with virtually all new printers or all-in-one devices like this one, Windows and Mac computers will automatically download the software on the computer recognizes the connected printer. All our Macs and all our Windows computers were easily set up for printing and scanning, with one Windows PC set up for faxing. Epson Remote Print was set up according to direction enabling the ability to print from a laptop or desktop computer to an Epson Email-enabled product anywhere in the world. Printing from mobile devices, from computers and as directed on the touch screen are all possible. Scanning to a mobile device, computer and cloud is available. Tipping out the bottom of the display for best viewing angle, it is time to . . . **PUT IT TO THE TEST** From a Mac, I sent a Web page to print, then a 3x5 photo in digital form. The photo lacked the snap I was hoping for, so I loaded a sheet of Epson photo paper. Much better! Copying (up to 100 copies) is easy both from the ADF or on the platen. Scanning, too, looked nearly perfect at all quality settings. Of course, higher resolution scans, as with prints and copies, take longer than at lower quality settings. Printing envelopes loaded in the paper tray worked well as expected. Scanning test – passed with flying colors. **WHAT’S MISSING?** There is no bypass slot for straight-through printing of iron-on patches or on any media that ought not to be bent and rolled through the normal paper path. All media must be picked up from the paper tray. **CONCLUSION** Except for a non-existent single-sheet bypass pick-up slot, this is a well-executed all-in-one printer. There is added value by virtue of inexpensive replacement ink bottles and the initial generous supply of ink included in the box. It’s a good deal all around. **WARRANTY** One year manufacturer’s warranty increases to two years with registration, including full unit replacement.

  • The Best Printer I've Owned
    Reviewed by SirGalahad - September 15, 2021

    [This review was collected as part of a promotion.] The main reason to buy this printer is the EcoTank. As that is where the money saving is. They report this printer should net you about 6,000 color pages or 7,500 black/white pages before needing to buy a new ink BOTTLE (approximate numbers which may vary). Those bottles bought individually are $20 for black, or $13 a piece for color. Or if bought as a bundle $39. Compare that to the traditional ink cartridge which prints about 220 – 350 pages per cartridge for about $17 (for black) or $39 (color) per refill (again approximately). Additionally, there is less waste with bottles as they can be reused and there are less of them due to lasting longer. Which is a win all around. These EcoFit Bottles also lock into place before they transfer the ink into the printer, so you aren’t going to be dealing with a mess and makes the whole process very easy even for novices such as myself. This is the whole reason I bought this printer. But you may be wondering why this printer costs more upfront compared to other ink cartridge printers. The reason is because their business model is to make money off their printers over their ink where it is opposite with others. In the end this actually saves you money in the long run, but you are paying upfront which some people don’t like. Thankfully, you still get a modern All-In-One Printer which supports printing, coping, and scanning. You navigate between all the options via a very small 2.4” touch screen which is very responsive but doesn’t have a glass covering which makes it feel a bit less premium. It can Fax 100 pages at a time. The scan resolution is 1200x2400 DPI which is good. I didn’t fax anything so didn’t test that. But did find that the scan resolution was good and didn’t have any issues with it. The biggest negative is the print speed. Which is 15.5 pages per minute for black/white pages or 8.5 pages per minute for color which is bit slow and not recommended for those who value speed and print a lot. Compared to about 20 pages per minute for black/color from your typical ink cartridge printer. Thankfully with a resolution of 4800x1200 DPI pages come out looking clear with easily readable print. Especially, if you calibrate the printer which takes some time but is totally worth it. I found it to be better than my other ink cartridge printers that cost about $100 – $200 which I would expect at a higher price point. For those who care it supports plain paper, photo paper (but isn’t a photo printer), glossy paper, and matte paper up to 8.5”x14” legal (normal printer paper is 8.5”x11”). The tray itself holds 250 pages (which is about half a paper ream) and it has an auto document feeder and supports automatic two-sided printing (which I really like as I hate doing it manually) which works well. Printer noise is minimal, the specs report 52 dBA, which to my ears is about right. Normal human conversation is about 60 – 70 dBA for comparison. They say the monthly duty cycle (how many pages it can print per month) is 5,000. Obviously, I didn’t test that because I’m not someone who prints a lot. Moving onto the smart features this printer supports either wired (ethernet) or wireless. Initial setup is easy. It will have you download the Epson Smart Panel app, which then literally walks you through the process of setting everything up via instant message which I thought was pretty neat. Through this it shows you how to install the ink, connects it to a Wi-Fi network (appears to only work on 2.4 GHz bands), goes through a 10 minute ink initialization (which can damage the printer if there isn’t any ink in it), went through a firmware update, alighted the printer for the best printer quality, Epson Connect (cloud printing aka smartphone printing), setup via wireless on a PC (usual way), and last you can setup fax features but need a phone cable to allow that which I didn’t do. Overall, the process was seamless and easy as it gave instructions the entire way with links when required. But was a lot longer compared to other ink cartridge printers (mostly due to that 10 minute ink initialization and alignment settings). You can connect directly to the printer via USB 2.0 (instead of the old school printer type cable). The same Epson Smart Panel App allows your smart device to print. You can also set it up to be voice activated. So, it checks all the boxes for a modern age printer. Overall footprint of the device is very small, especially for how much it can do. Which I like A LOT. The build quality is great and a lot better than your typical printer. I found it to be the best “home” printer that I’ve ever felt regarding build quality. With the only loose tray being the one for the paper. I like that you can see how much ink you have left by peering at the front bottom right which isn’t digital but a window. Which I prefer over a digital reading and keeps me up to date on my ink usage better since it’s kind of right there. Touch screen doesn’t have a glass front (which makes it feel not as premium) but touches are very responsive and accurate. When I was scrolling or going from menu to menu I didn’t notice any lag. There are also a lot of customizability settings such as quiet mode. It also shows how strong of a connect to the Wi-Fi you have along with the Bluetooth connection to your phone. Epson App is also easy to navigate and user friendly. CONCLUSION: This is an excellent printer that you pay upfront for with savings later due to the ink savings. Print speed is a bit slow and initial cost is high. Touch screen could be bigger but is very responsive without lag. Epson Smart Panel App is useful for those who only own smart devices (phones/tablets). Overall, I have very little cons with a lot of pros. I find it to be a worthy investment if you aren’t printing a crazy amount of pages monthly and don’t mind slower print speeds. It’s easily the best printer I’ve ever owned. But also costs about 2x as much.

  • Flawless! Best printer I've used!
    Reviewed by mgwexford - September 22, 2021

    The Epson Eco Tank ET-4850 was a wonderful surprise for this home office user. It is compact, quiet and the easiest functioning printer I have ever used. The setup is, without doubt, the most seamless and fastest you can imagine. I have read and listened to reviews about the EcoTank instead of ink cartridges and was doubtful about the results. Well, doubt no more. Everything you hear about this compact beautyis the truth. Let me tell you what I experienced. First, this all-in-one came packed in a great sturdy box with really secure packaging inside so that the printer would not shift or move during shipping. It came out of the box easily and was surprisingly light compared to my previous Epson WF-3740 that was a true workhorse. Setup with the easy to read instructions and the Epson app was amazingly simple. I must admit that when I first started the download and connection to my home network, I expected a long process that had been my experience in the past. This was so quick I was amazed. The speed of this ink jet printer is about the best I've seen. It has the capability of duplex printing and does it quickly and effortlessly. The ink bottles are a game changer. I was a bit apprehensive at first. However, this was about the easiest process I could imagine. Each color ( black, cyan, yellow and magenta) each came in a separate bottle. Here's best part: each one of them has a specifically designed nozzle that will only fit it's corresponding color, so you can't screw it up! YAY! The bottle automatically empties itself into the tank which has a window on the front so you always know your ink levels. Now to printing which was amazing. The print quality was crisp, bright and very high definition. The photos were just the best I have ever printed and my husband (amateur photographer) was tickled pink with the results. His still life photos had depth and clarity that heretofore had never printed so beautifully. Kudos to the print quality. The scanner is great. It worked so easily and produced such high quality results I was truly impressed. Scanning either to print, the cloud or to save to memory all went off without a hitch. It scanned with far more detail than I have had before. The copier is just the best, I have to say. With the number of copies that I have to make on a weekly basis for my class and groups, I can't ask for a better copier. Just as the scanning and printing, the copies come out clear and crisp. Works for me. The touchscreeen display is bright and the presets help with and easy flow of the tasks. It takes you from step to step through the setup and for whatever task you need to complete with this little gem of an all-in-one Epson ET-4850. No more ink cartridges for me! This is a review for the Epson EcoTank ET-4850 Wireless Color Supertank Printer that I received free of charge to do a beta test and review.
