Epson Epson Stylus Photo RX620

Epson RX620 Ink cartridges cannot be recognized

Have a Epson rx620, color on prints started looking off, ran a nozzle check black was virtually nonexistent. I removed the black cartridge and reinserted it, after that I started getting the message that the ink cartridges cannot be recognized (all of them). So I removed and reinserted the cartridges and power cycled a few times and it started working again but still no black. I went to the store bought a new black cartridge and inserted it, but now the message saying that it cannot recognize any of the cartridges is back. All the cartridges appear to be genuine and do not look like they have been refilled.

I just tried removing a couple off single cartridges thinking that there maybe be a problem with one of them. When I remove a single cartridge it only shows that it cannot recognize that one , but when I have all the cartridges back in it cannot recognize any of them.
I hope this helps somebody...
I found that if after I closed the latch that locks the cartridges in place I push down on all the cartridges a few times the error clears and the printer works!

After many attempts at other helpful suggestions, this one worked for me!!!

Thanks so much...

Tried this and it worked first time, thanks you so much. A real simple answer to a mind boggling problem. Clever chap. Many many thanks! - FulhamGaz
THANK YOU!! I've been installing and setting up my new RX690 today and getting so frustrated with that error message. Gave the latch a bit of a push, as per your suggestion and what do you know - it worked! Pure genius! Thanks again - meagss
THANK YOU!! I have been fighting this for 3-4 hours today, and could not get it to work. That irksome message just kept popping up.
I tried pressing down on the cartridges after reseating them, and voila! It works!!
Many, many thanks! Thought I was going to have to get a new printer. I have been using replacement cartridges from ABCink.com, and have never had a problem with them - until today! Pressing down fixed it. I had even tried replacing with Epson cartridges - reset, and even that didn't work.
Thanks again. - unknown
thank you so much!! this actually helped after hours of troubleshooting!!!!!! - unknown
I have been frustrated for a long time about this problem...called epson, and they could not fix the problem. This worked for me!!! I pressed on all of my ink cartridges and presto, it began working again...thanks for your post!! - Anonymous
I have had this message several times. I remove the cartridge and rub a soft tissue over the gold part of the cartridge. Then replace. This does work. Good look.

My thanks to AJCrafts for the tip on cleaning the chips with a soft tissue. I use Jettec cartridges and when I replaced the light cyan I got the message that the cartridge could not be recognised.After removing and then replacing it, I got the message that none of the cartridges could be recognised.Searched high and low for an answer until I came accross AJCrafts tip.I removed the light cyan only, cleaned the chip and when replaced the printer went into 'ink charging' mode and all six cartridges were recognised.Brilliant. Many thanks. - Anonymous

In the Epson printer utility try the Nozzle Check and the Head Cleaner Utility. I did it and it printed the sample and recognized the cartridge.

Rubbed a kleenex over side chip heavily and shook up and down then pushed each cartridge in slot with some force, slapped the cover shut and pushed down sharply ( somewhat frustrated by now ) and it worked. It says genuine epson ink even though it is not. EPSON SUCKS, but we still win. YOUR A LOSER EPSON, I BEAT YOU

I tried this several times without any success. This will be my last Epson Printer. I always had HP's, but hated the tri-color cartridges because I felt it wasted ink, but this is just as bad, will not print or recognize cartridges when they get low. The printing quality of my previous Epson (R220) was great. I had some of these problems, but not nearly the problems I have with the NX415 and the print quality is not as good. Of course they no longer make the 220 and mine finally said it needed service. I figure that is another Epson rip off.

My Jet-Tec Magenta has just failed again when half full. I've had no joy with the clicking, slamming, chip cleaning, nozzle cleaning etc. over the 3 years that I've had my DX 8450. Many cartridges will not work again if removed and replaced even if they aren't showing a fault, maybe it upsets the charging or the chip memory ? Just guessing. The local engineer advised me to run proper Epsom cartridges through it every 3rd or 4th cartridge or when it failed as this acts as a cleaner. Just passing that advice on. Rip-off prices but it seems to work. - Anonymous
I tried all of the above and then took a Q-tip with a bit of isopropyl alcohol on it and gently rubbed the inside of the cartridges holder where the sensors go. I then reseated the cartridges and pressed hard against the holder. It finally worked! Go figure!

Thanks to everyone for their input....these tips ought to be on Epson's support page.

The rubbing alcohol applied with a Q-tip to the sensor inside the printer finally worked! This was after reseating, pressing down on the tabs, wiping the chip with tissue and even the machine with tissue and Q-tips didn't work for my NX400. Thank you and God bless you all! - Anonymous

I found this link on the internet. Seems like Epson keeps changing the little chips on the cartridges which can often cause a full cartridge to show empty or not an Epson cartridge. And even make all of the cartridges show as non-compatible. So I carefully scraped off an old chip from an old cartridge and put it on the new. It worked. How long it will keep working I have no idea. I am thinking of going with CCS reusable cartridges next time I have a problem. One thing for sure, I won't buy an Epson printer next time.

Thanks Tom King, you're a genius. After a long fight w/ my epson RX590, thanks to you I got the guts to replace the damn cartridge chip with one from the old cartridge that was empty, and IT WORKED. I was almost on the point to trash the printer, and the worse is there is not many (and better, and cheap) alternatives for the functionality I need. Thanks again, and baaahhh to epson and its stupid ideas that make us spend time and money! - unknown

Wow, am I ever glad I found this thread. Thanks to all who shared here. I am the "fortunate" owner of an Epson printer which is refusing to recognize my EPSON ink cartridges AND saying there is a paper jam when there is not. LOL I have tried most of the suggestions to get it to recognize the cartridges... including the rub them hard, shake them furiously and pound on them (there is a point beyond which you don't care) :) -- all to no avail. This is the FIRST time I have changed the ink cartridges!!

I had no idea the problem was so widespread. But... but... but...

Today I ALMOST bought an R-1900 photo printer! I had every intention of buying it until I read all this and realized what a mistake I was making. This is my first Epson printer and up until now has been my favorite. But I am headed out tomorrow to buy my first Canon... since I won't even consider an HP due to past experience. How on earth is Epson avoiding a class action lawsuit?

Been having this problem with an Epson Photo RX585. Either it stops printing or when the JetTec ink cartridge is about 25\% full says it cannot recognise cartridge. Tried all the fixes above but couldn't get to recognise compatible yellow and light magenta cartridges - both new!!
Fortunately I had a new compatible magenta and the old yellow cartridge. Swapped for these and it recognised them. Once I had replaced the empty yellow all was working again. Would recommend keeping your old cartridges to swap out to when this happens - it may fix your printer.
All in all, I am not happy having to go through this routine every time I change cartridges. Have been using Epson for years without issue but now will not buy Epson again. Was thinking of HP but other users seem to prefer Canon - what would other users suggest?

None of the above worked for me...I am so frustrated. I also had a previous Epson printer that worked great for several years so I didn't think twice from purchasing a new one. But I will NEVER own an Epson again. I promise you that. Epson should have a class action lawsuit filed I agree. They spent so much time developing a cartridge that cannot be "refilled" yet their own printers don't even recognize them! That is absolutely unacceptable. NEVER AGAIN!!

Have 2 Epson Printers - R340 3 years old and no problems. Bought a SX415 4 weeks ago for it's scan and copy capablities and after 160 black A4 prints I was told that the cartridge needed changing. Man in the shop told me it was probably only a part filled cartridge that came with printer. Started to get worried.
Black cartridge 'emtpy' again, another change but guess what ? Cartridge cannot be recognised and by the way, the yellow needs replacing too ! Hours later after head cleaning etc, all ready to go but copy comes out blank apart from a few smudges....... Reading the problems of others I am off back to the shop tomorrow to claim my purchase was not fit for purpose. Their problem, not mine. Watch this space. I might just buy an alternative - time is money after all and am not going to waste it chasing a manufacturer who appears to be selling a product with which so many people are having a problem.

Yea, it's too bad this crap happens. It only happens with some of their printers. I have 3 Epsons and experience this problem only with my RX620.

Since I cleaned it, I've had far fewer problems. Replacing the chip from another cartridge also helped. See previous discussion.

All that said, you're right. It's not worth the hassle. Buy a different printer.

If your cartridges previously working and the printer suddenly can't recognized it There's a way to fix it. The cartridges terminal is not fitting to the printer terminal that's why the printer can't recognize it properly.

All you have to do is hit the side of the printer until the printer and cartridges terminal if perfectly aligned. But if you want to do it the easy and most formal way, remove the cartridges clean the terminal and put it exactly as needed to make the terminal of each device connected. Still not working? Clean more and fit more. That's ALL!

Have read all these useful comments but can't find the one magical/miracle solution I need to this problem:

My all-in-one Epson Stylus Photo RX520 (out of warranty) has been working OK for the past 3 years using very reliable compatible inkjet cartridges. But a couple of days ago, after I replaced an empty cartridge, the plastic cover of the cartridge holder refused to click shut as it normally does. It closes but remains slightly above its proper level. I tried re-inserting all 4 cartridges (all are brand new from the same company I generally use) and they all click into place as always. Also tried pushing down again as suggested above. Still the printer won't work. The LCD message shows that the lid is not closed (it is) or that the Magenta cartridge is empty (it's full). I've tried everything I can think of but still no joy. Contacting Epson support is useless: they just tell you to buy a new printer. I phoned some printer repair services but either they don't deal with or it would cost more than a new printer. I'm sure all it needs is just a small adjustment to the plastic cover of the cartridge holder so it will click fully down again, but how to do that?
Before I stop tearing what's left of my hair and give in (as Epson wants us all to do) and buy a new printer (it WON'T be an Epson!) I'd like to solve this tiny problem:
Can anyone help? PLEASE!

Thanks to all of you for guiding me through this trouble-shooting! I've been through so many steps and problems I'm not sure I can repeat them, and I still haven't solved the problem of not getting black ink. But I DID manage to get the printer to recognize the cartridges.

First, the black ink was not printing. I tried head cleaning, and it said I couldn't clean the head a second time unless I first replaced two print cartridges. I replaced the magenta and cyan with the exact same brand I had used before (I buy compatible cartridges from 4inkjets.com - LDProducta), and then it said the ink cartridges cannot be recognized. I pressed and wiped the chips with a tissue. At least I finally figured out that they were only complaining about one cartridge, the cyan one. I discovered it was really easy to put the old chip on the new cartridge, but none of these steps helped. It still didn't recognize the cyan cartridge.

By the way, at that point the printer was saying that three of my cartridges were genuine Epson cartridges, even though they were really compatible ones.

Then I replaced the Cyan cartridge with another one from the same source, and then it recognized the print cartridges and reported they all were genuine Epson. But the black ink still is not working.

So then I took a Q-tip and rubbing alcohol, and washed the area where the ink goes into the printer (around the little black piece that goes into the print cartridge at the bottom). It looked fairly goopy.

But then when I put the cartridge back, pushed down, and closed it. Then I got a message that

Folks...let me say straight off that my RX620 printer is over 5 years old. Nothing made today lasts very long, and printers are no exception. Planned obsolescence is what makes money for the makers.

That said, sometimes you can get them to work again, for a while. I've posted a couple to suggestions earlier on this issue. It got my 620 up and running again. But last week, it quit right in the middle of the page and said my light magenta ink was out. I put in a new Epson OEM cartridge and got the same message.

Tried the usual steps of pressing down, reset, etc. No luck. Then went to the Q-tip, denatured alcohol and cleaning the entire inside of the cartridge box, especially the front wall channels where the chips are read. Also cleaned the ink sponges...carefully....and the track. Lots of messy, dried ink in there.

Turned it on again and lo and behold it's working again. For how long, I don't know. With all the time I waste on it, I'd be better off getting a newer printer. The refurbs are a lot cheaper. IF you decide to do that, check on the internet about cartridge costs and amount of ink used, That often adds up to more than the cost of the printer if you used it often.

If you don't use OEM cartridges, I'd suggest taking a look at this website. Their reusable cartridges are much cheaper and they give good advice and responses to your questions:

I have an Epson Stylus Photo RX560 - about 4 years old.
I put non-Epson ink cartidges in, the printer was initially fine but then a day later it suddenly did not recognise the magenta cartridge and went on strike. This was really annoying as I only wanted to print a text document so only wanted to use black ink, but the printer refused to do anything at all just because it didn't like the magenta cartridge. Anyway, went through all the advice on this page, none of it worked except the one about swapping the gold chip over from the old cartridge (which I had to recover out of the rubbish bin!) onto the new one. It was actually really easy, no scalpel or glue required! just snapped off and on. The printer is now happy and has begun working again. Good luck to us all.

I had the same problem with my workforce 600. I tried all the cleaning, jamming it in, everything and none of it worked. The yellow still wasn't being recognized. I saw the post above about the chip and thought maybe that was the issue. I noticed that the magenta cartridge had a slightly different looking chip, so I checked the replacement Epson cartridge. It also had a slightly different look (the chip that is) and once I put in the new cartridge it worked. I'm keeping the cartridge that didn't work and bringing it with me when I buy other cartridges to make sure I get the right one. Keeping my fingers crossed....Thanks guys!!

I did the same thing that was mentioned above. However, i used hand sanitizer and a q-tip. I used above normal force to put them in after shaking them and i figured that i wouldn't work and as soon as i clicked the OK button it said "Charging ink. Please wait." I'm so excited and thank you all for writing this. Now it says "Complete" How happy i am. I was really ready to throw this f*cking Epson Workforce 615 out of my window.

Just thought I'd give feedback as I found this thread after Googling my Epson SX415 not recognising a new and genuine Epson cartridge.

I tried loads of variations of wiping chips, making sure it was clicked into place, following Epson's vague "turn it off and on again" type instructions. I mean loads of variations. For a long time.

This forum led me to resorting to angrily shaking the cartridge and instead of clicking the cartridge back into place, SMACKING it down, much much harder than before.

It now works again.

Go figure. You may try shaking alone before smacking, but hitting it did feel good ;)

Thanks for the tips.

I replaced an ink cartridge in my Epson printer, and I also got the message that it could not recognize the cartridge. The only thing that worked is when I switched the chips between the old and new ink cartridges (the chips snap out/in the cartridges easily). Now at least the printer recognizes the new ink cartridge.
However...now I get a different message: "You need to replace the ink cartridge." I tried shaking the cartridge, and turning my printer off/on, but the printer still says I need to replace the ink cartridge, even though it is full of ink. Any other suggestions to get the printer to realize the cartridge is full of ink?

I have had a problem with my printer (Epson Stylus RX585) not recognising any cartridges all of a sudden after I had replaced two empty ones. I tried everything suggested on this page and nothing seemed to work. At the end of my tether today I was going to bin it and buy a new one (AS EPSON ADVISED!!!!! They said the repair cost would probably be more than the cost of a new printer!!!!) and then I accidentally stumbled across a fix! Here it is:

I took out one cartridge and then closed the carriage lid and pressed "ok". The printer then informed me that just that one cartridge needed replacing. So I replaced it and then immediately took out a different one. So now the printer tells me once more that just the absent one needs replacing......

BUT.... when I pressed "ok" and the carriage returned, the screen now said I needed to replace all APART FROM the first one that I removed on its own! So I repeated the process, removing a different cartridge every time on its own, pressing "okay", and then simply replacing it and removing a different one until the LCD display said that there were no more that needed replacing! Completely BIZARRE workaround but it seems to have worked!!!

Hope this helps someone else! :) This problem had been driving me INSANE!!!!!! :>

I have tried everything all of the above. Nothing except (maybe) changing the chip...except the chip I am using is from my cartridge that had just run out... and when I put that in it says... the cartridge has run out. The chip must remember that the cartridge it was on has run out! I am using genuine Epsom cartridges, and when the get to about 1/2 full the printer no longer recognizes the cartridges.

Only use epson as I use linux, and Epson seems to work better than the rest under Linux (except for this issue). Will go CISS if I can get it to work.

This is the first epson printer that i've ever got and brought it on the recommendation that it was ideal for students because of its individual ink cartridges. It worked fine up until i had to change the black cartridge, put in a new epson cartridge and its telling me that the new one has less in than the one i'm replacing tried all itsthe suggestions here and its still not registering that its full.

The printer reads the ink level off the chip on the cartridge. If this was an original Epson branded cartridge take it back to where you purchased it and have it replaced. If not an original Epson cartridge, anything goes. Hope this helps.

I've replaced the black ink a few days ago and in the first days it worked fine, but yesterday I've got the message " Black Ink Cartridge Not recognized". I've tried all the steps you've told about in the earlier posts and nothing (I didn't clean the head because I don't know how and I assume it is too earlier to clean the head because the printer is just a few days old).
I've noticed that the chip of this new ink cartridge is a little bit different then the other, though it is still a genuine Epson ink cartridge.
Any help please?

Tried cleaning contacts, repowering, etc to no avail. Still had "...cannot recognize.." on yellow and cyan. Called Epson tech support at (562) 276 4382, filled him in on hstory, and he said to violently shake the cartrige before re-inserting. First the yellow came back, then I had to re-shake the cyan, and it came back. I've had the printer since 2008, and it performs better than the HP's I've had. I think the key is having the direct number to tech support. There was no waiting at 11:00 am.

epson sux, if the unit is under a year old, and you have proof of purchase, call Epson at 1-800-GOEPSON. They will replace it under warranty. Hope this helps.

Thanks to everyone for the advise, tried all the tips to no avail. Lost my temper after an hour and banged the top of the ink cartridges really quite hard and would you believe it problem solved.

As silly as it sounds..... also make sure you have the correct ink cartridge. Some of the cartridges are physically interchangeable, but will cause these problems to happen.

I have a weird problem: I installed a black ink cartridge T0481 (it's not an actual Epson cartridge, but I use them all the time and they've never given me a problem before) to my Epson RX620 printer. The printer registers the cartridge and says that it's reading it and whatnot, but when I go to print something in black...nothing. All the other colors work, and I tried changing out the cartridge for a fresh one, but the same thing happened. If anyone's even still paying attention to this thread, please help!!!

The Black part of the printhead may be clogged. Try running a few cleaning cycles. If that does not work then buy a kit like this http://www.fixyourownprinter.com/kits/epson/K89 Heat the cleaning solution and follow the directiond.

Try calling Epson tech support direct at (562) 276 4382. I was at wits end, and thought I tried everything. Their tech support really helped.

Delphia...Don't recommend cleaning any manufacturers printhead with alcohol. It will dry out the rubber components in the head.

After I changed a cartridge, I received a message that none of the cartridges were recognised. I took the cartridge out, cleaned the gold contacts (I could see dirt on them), replaced it and then received the message that only the new cartridge was not recognised. I took the cartridge out again, re-cleaned the gold contacts, replaced it and then everything was ok.
The lessons of the episode are;
Only replace one cartridge at a time so you know which one is giving you trouble and, secondly, clean thoroughly!

Hi there!

I had the same problem, 0805 (light cyan) cartridge wont be recognized.
After 5 mins of staring i see that one of the contacts broken on the printer head.
Because i was not able to solder the head (i did not try it, i now it is impossible) i soldered a piece of wire in the ink Cartridge. 2 minutes and it works fine.

Now i have to solder on every new 0805 cartridge a piece of wire, but never mind :D
