No Printing after print head and nozzle cleaning

After a while without use my Epson Wf-2750, replaced all the ink cartridges & performed print head cleaning (several times) through printer, printer is not printing nothing at all. The carrier moves left to right as is printing but no ink on paper. Paper are blank without any trace of ink, no printer error, nozzle check page is white too.

I decided to clean the nozzles thinking are clogged. Were cleaned with a syringe and cleaning solution until “clear” solution/without any trace of ink came out. The problem persist, white paper came out.

Last cleaning was “deeper”, removing the print head and with the syringe cleaned the nozzles until all “perforations” from print head were cleaned and solution pass through. This was performed to be sure that those “perforations” were unclogged. The problem persist, except that a light blue ink printed a status page. But when running a nozzle check no ink at all.

The big question, what’s happening and how can be fixed?

Thank you

Answer this question I have this problem too

Hi @sandman8888

Thank you for your advice and time. The problem persisted, so just bought a new printer.

Excellent solution that beats any advice you get here. All that advice about ink cartridges... the Epson 2750 does not use cartridges, so most of the advice above was nonsense. Why do people do that?

by

People do that because they have reading comprehension skills. The OP states he has a Wf-2750 not an EcoTank 2750, so it most definitely takes cartridges. While replacing a printer often makes sense, the cost (both financially and in landfill detritus) is not always the best option.

I've had this issue multiple times with another WF model. Unfortunately I can't give a tried and true answer, but here are some tips that have worked for me in the past to some success:

1) After cleaning with solution, allow the printer to fully dry (6+ hours if possible).

2) After replacing cartridges allow them to sit in printer for up to 48 hours before determining if issue is resolved or not.

This seems to happen when a print head hasn't been used in some time, either because out of ink or simply not printing. I have a scheduled print job to run weekly to at least make sure some ink is expended. I had an older Brother printer that did regular print head cleanings - was annoying and ate up ink, but never had this issue.

Thank you for your comment. I have gone through a complete set of new ink cartridges trying to get my WF-2750 to print after sitting for a long period with no success yet. Still getting blank pages. Just wondering how many new ink cartridges I need to go through to get it to work. Very frustrating.

I have done the clean print head process many times, put new genuine ink cartridges in and still I get blank pages. I hate to add another printer to the landfill. Can anyone suggest what I can do to get this printer working? I hate to keep wasting ink as it is expensive and have already gone through a complete new set of ink running clean print head process to only get get blank pages printed.

I've experienced this same issue with two different Epson WF model printers - in one case the printer was not used frequently enough and in the other case, two of the 4 the ink cartridges were used till they were completely empty but the printer still allowed pages to be printed (the empty colors started showing more streaks and at this point I assumed air was contaminating the lines). This happened with genuine Epson ink for a WF-C5710 MFP. Here is what I did to get the printer working again - not guaranteed to work but it's what I did.

After realizing the ink was completely empty I changed those cartridges and any other cartridges that the printer showed was low (I used generic, 3rd party OEM ink as I knew I'd have to go through many cleaning cycles), then I printed the first nozzle check print out from the printer's on-screen menus. That print showed 2 colours printing properly (magenta, yellow), 2 colours with gaps in the pattern (the ones that were previously completely empty black and cyan) and the printer offered the option of a print head cleaning, which I accepted. After the cleaning I reprinted the nozzle check and was surprised to find that the pattern had degraded severely - the 2 colour printing properly were the same (magenta, mellow) but the 2 other colours had nothing in the pattern (black, cyan), I repeated the cleaning/ nozzle check cycle with the same terrible results (no cyan or black printed in the nozzle check pattern). I did 7 more cleaning followed by nozzle check cycles with no improvement at all. I turned the printer off (using the hardware buttons) and left it overnight to resume the following cycle the next day: nozzle check, followed by 20 printed pages of a CMYK test pattern (found a sample online that had a page of cyan, magenta, yellow, black patterns and blocks), followed by cleaning, followed by a 30 minute pause with no printing. I repeated this throughout the day, sometimes leaving the pauses for longer than 30 minutes depending on my other daily tasks. The results of the nozzle check printed pattern and the CMYK test pattern for the first 9 cycles (on second day) were atrocious with gaps everywhere, completely missing colours (cyan, black), and variation each time was very discouraging (sections that printed fine in a previous cycle would suddenly show many gaps or not print at all). I believe these varying, inconsistent results were the result of air bubbles working their way through the lines - then by the 10th cycle, I was surprised to see the black ink began showing consistently in about 25% of the pattern, but still no cyan. In each subsequent cycle, the black coverage improved and by the 15th cycle I started seeing speckles of cyan, while the black had returned to about 50% coverage (magenta and yellow were always fine). By the 20th cycle, the black was back to 95% and the cyan was 50% coverage (I'm estimating the coverage based on how much the nozzle check pattern was printed for the respective colors). This was a significant improvement from the start of the day. I had to leave the printer overnight and repeat the same thing the next day and eventually got both black and cyan back to 95% coverage of the test pattern - I stopped after that point as I had done over 30 of these cycles, I didn't have the energy to get a 100% perfect nozzle check and the output was sufficient for home use at that point in the recovery.

I think what helped was the printing of the CMYK test pattern pages (to 'exercise' the ink lines by printing enough pages to encourage flow of ink for all the colors and to allow the bubbles to work their way out of the lines) and the pauses to allow the cleaning cycle to "stabilize". It took a lot of cleaning cycles, paper, ink, waiting and patience because the improvement is not steady (and downright discouraging) in the earlier part of the routine. It may not always be worth this effort but I had extra ink (for all the colours) that would have been discarded anyways and I had time.

Going forward I will do what others here have suggested - changing the cartridges soon after the low ink warnings.

Wow, thank you for that in-depth help. I can't see myself doing it all, particularly since we acquired another printer. We can donate this one to someone who will hopefully get it into working order. I will definitely forward the suggestion/process on to them. Thank you again for your detailed assistance.

I don’t see any reference to you forcing new ink through the print head to prime it. That finally got my WF printer working again after a long disuse period. Also this to stop this happening in future…

Above post is ubuntu linux based but you can do similar stuff via mac or windows utilities as well I suppose.

Hi, I had the same thing..

I direct injected ink that I took from an used cartridge directly to the printer head (printer head was mounted ) - I had the problem with the black. After that I selected “clean head” around 4 times. You will need to print some black pages (around 20), “clean head”, print again. That’s works for me.

Update (01/26/2021)

Also I replaced all cartridges in the middle of the procedure..

I don't think the clean head and printing black pages is the answer... but your update (replaced all cartridges) seems to be the one that did it for me, although you really just probably needed to remove all the ink cartridges and put them all back

I have had this problem several times already and it is very frustrating. It doesn’t matter if your ink is genuine or not.. in fact, it’s worse if its genuine coz I find that the ink runs out quicker. I find that you shouldn’t wait for the ink to run out completely… you should replace it as soon as it gives you the warning. Also, I found this out recently… my black ink run out on me and I replaced it twice… with generic ink and with genuine ink, and it didn’t print out even after manually cleaning the print head (by injection) and print head cleaning via the maintenance mode - it did this several times, even printed out black pages which turned out blank… I finally gave up and hit ink replace, then pulled the plug so I can freely move the ink cartridge caddy… took out all the ink cartridges, didn’t really do anything and put back all the ink cartridges one by one… it miraculously worked after that… beats me why that worked but my guess is air bubbles?
