I would change to an EcoTank if I were you.
First time I have ventured into printing with refillable ink and I must say I am very impressed. I have had many Epson printers all with cartridges. I have always bought compatible ones and have constantly dodged warnings, naggings and refusing to print because of it, and they never lasted that long anyway. This is a game changer. The reservoir is huge compared to the cartridges offering up to 72 cartridges worth (they say) of ink. And you get this included with your order. Even when pricing original Epson ink it will work out cheaper and no nagging. Plus, you are doing your bit for the environment and giving the manufacturer all the money to invest. True the printer is a lot dearer but will work out just as cheap or cheaper if you are keeping it for the duration. The actual filling with ink is a doddle. The bottles have been ingeniously designed from the ground up to fit each tank individually. They don’t spill and the ink stops flowing when enough ink is in the tank. I was a bit apprehensive about doing this initially but it’s easy and not messy in the slightest. Epson have put a lot of effort into setting up their EcoTank models. You can install it perfectly and easily from new by downloading the setup APP to your smartphone. This communicates with the printer from the outset and expertly guides you through the whole initial set up process with pictures and confirmations at each stage. Leaving you with an initialised product ready for connection to your computer. This to is easy as it links itself to a specific setup page just for the model and does all the work for you just by responding to the questions. Mine was a Windows 11 installation. Very clever and very simple. It all takes a bit of time but patience is a virtue. The new software is good too. One example is organising scans from the scanner. The software is intuitive. Organising pages is easy and it can even intelligently rotate pages. This more or less does away with spending a lot more on double sided scanning as there is so little effort in just popping the pages back on the ADF knowing there is minimal effort needed for sorting. It takes up a small footprint for the amount it does. It is relatively light as well. It does feel a little plasticky but I don’t think so much so that it will fall apart. It just appears functional and is. The screen is small and is not touch meaning you have to keep pressing buttons and then okaying. Shame I would have loved the touch screen so much better. Also, when you lift the scanner unit it only holds in place when you force it upward so that it locks. I found this nerve racking as I thought it might break, I am sure this could be better manufactured. I will not be printing photos on it. For me it is meant for office type documents and they have all printed really well so far. It prints double sided also. I am more than happy to give anything I print to anyone who I believe should find it much more than acceptable. I do use decent paper. Perhaps the only down side is it seems to be a little slow in everything it does. Don’t get me wrong in no way a deal breaker for me but if you were in the office and want everything at speed then perhaps another model may better suit. I note some people are reporting a WiFi issue mine worked straight away although I cannot know yet whether this will come to haunt me. But there is the 5 year warranty which Epson are currently offering on their EcoTank models. Overall, I am extremely pleased so far. Far better than my Epson’s of old in terms of hardware, ink printing and software. A great upgrade. At this stage I am glad I bought it. My major gripe was Amazon reducing the price 2 days after I bought it.

Cost effective, easy to set up, cartridges are cheap and long lasting.
Best printer I ever got. I wish I had found it sooner, it would have saved me a lot of money.

Good Photos but Deeply Flawed - PLEASE READ
Update 24/11/25 I have taken the trouble to update my review becasue I am totally gobsmacked that the awful ET-3850 is still available. For all of you out there looking at the many positive reviews, take my word for it that this rinter is not for printing photographs. It work fine for b/w but and indeed it prints a nice photograph. But if you want to print a number of photos - not just one or two - it WILL keep ejecting paper and tell you that there is none in the magazine. It's still £300+ plus and behaves like a £50 printer, fit only for b/w or occasional photographs. I have to sit alongside it constantly trying to convince it that it has paper. They even suggest cleaning inside with isopropyl alcohol. They know this printer is badly flawed but they carry on selling it. Do yourself a favour and don't be a mug. AVOID the ET-3850!!!! I bought this for a large photograph printing project that I have undertaken. It was recommended by Which? for the purpose. I need to start off by saying the project - 100s of A4 photos - would be absurdly expensive with a cartridge printer. I used the supplied bottles quite quickly - on A4 pictures at Highest Quality - but in normal use they would last for ages. You can use generic ink which is cheaper than Epson and I couldn't see any difference, The quality of printing is, to my eyes, very good. Now onto the problems and idiosyncrasies. Firstly, my early pictures had horrible colour casts - often orange. After trying all sorts of paper and all sorts of settings, the truth dawned on me. This happened with any picture I had photoshopped! I also use Luminar Neo and this causes no such problems. So this must be down to Photoshop, not the printer. The printer, however, tends to print darker than on your screen so before printing a photo I strongly recommend you rauise the brightness of your picture and. in some cases, reduce the colour saturation. The user interface on the printer is much too small for its complexity and there is much fiddling with buttons. It is very frustrating and not for those with poor eyesight. The panel is like something from twenty years ago. The software is also confusing and there are far too many modules. Ease of use is very poor all round. In fact I hate the user interfaces. Then the biggest issue - the Wireless function. Want to print a few pages on plain paper? Its fine. Want to print A4 photos on glossy paper? It's a nightmare. Too often pages come out half-printed after lots of clacking and whirring at which point the printer asks if you want to check the connection. It repairs it. Half a dozen pages later it happens again. I found out on a forum that it's a common problem with no solution despite Epsons's feeble "answers" such as updating the firmware etc. What's more, it seems that, as it did for me, this problem emerges after a while just when you think you have bought a great printer. The only solution - obtained from a forum - is to connect via a usb cable and this solved the problem for me. You can install a usb connection whilst keeping the wireless connection for more everyday tasks. You CANNOT, however, use an Ethernet connection next to your wireless, connection. I can only think that there is some sort of buffer in the wifi interface that causes problems when it overflows. I repeat, you will find many people have had this problem. Then there is the paper handling. Plain paper - no problem. Photo paper? It will drive you mad by unnaccountably ejecting sheets before finally finding one it likes.. Bizarre and annoying. USB connection cannot solve this issue, of course. Whether changing brand of paper would fix it, I don't know. Overall, it prints good pictures but the shortcomings have meant my first few months of ownership have been a bit of a battle. How a company like Epson can produce a £300+ printer with so many issues is something of a mystery. Like all ink tank printers it can save you a fortune in ink. But I can't help feeling there are others as good but less problematical in use out there. Thumbs down for Which? as well as Epson frankly. Update 15/9/25 : It's now just terrible. It will print a batch of pictures then decides continually that it is out of paper. You can re-feeding the tray, fanning the pages, whatever but it still keeps happening. There's a lot of clacking and whirring and sure enough, up comes the "paper out" message. This is the most frustrating pievce of kit I have ever owned. You would be mad to buy one.

Great printer for ink management
This is a great generic printer/scanner/copier/fax machine (even ignoring everything past "printer"), although the colours are a little too washed out at times - the black isn't black enough, the colours aren't really VIBRANT (even on photo paper) For the way EcoTank works, this is fantastic, the ink levels being visible and being able to be topped up before they run out is a genius idea, and makes it a million times better than other colour printers, especially the ones where the colours are all in the same cartridge (which is a HUGE waste of money), which makes the ink management a breeze Strangely the setup wasn't as easy as it states in the box, I tried it on the mobile app but it never connected to the wifi, resetting it and plugging it in was MEANT to setup everything, but it was then "forced" to be used wired rather than wireless... but once it was setup and on the network (lots of manual entry) setup on my work Mac was stupidly easy, it just did it, while the Windows install was a complete pain in the butt! Once it's setup though it's really simple to print to, from multiple devices, and when it's on wifi it can live anywhere that's useful or out of the way My reason for not giving it five stars is a bit odd, as they don't properly "announce" my requirement, but more hint at it - I need to print on card stock, and this listed that it printed on 300gsm photo paper, so I thought it should print on 300gsm card, but alas, it did it once and then never fed the card again... trying 250gsm had the same result, but the only one that ACTUALLY worked is 200gsm, which is not quite stiff enough for real card printing

Très bonne qualité d'impression tant sur du papier ordinaire ou du papier glacé photo. Il faut juste s'assurer de bien régler les paramètres. Le recto verso fonctionne bien avec un temps de séchage entre les couches. Le scanner n'est pas très rapide mais très correct. Le logiciel de scan ne permet pas de réglages avancés mais il fait le travail. Fonction copie autonome bien pratique et plus vite disponible qu'une imprimante laser.
