    Ok, so I have taken some photos to show the air.
    The nozzle check hasn't changed since the day we have it. after all cleanings it is constantly the same.

    Re: epson 7880 service manual

    you need a new print head if the nozzles never change, never seen one quite like that, it may be a head striking the page thats damaged it.

    fixed price repair is my suggestion, give epson a ring, tell em how many cleans its had and the results are unchanged. let them quote you and see what you think.

    other options taking it to tewkesbury to equinox maintenance ltd


    get both to quote you.

    Re: epson 7880 service manual

    i had achat with epson today and fixed repair for this printer is just over £1000, so i would imagine maybe a good option. on the other hand, would it hurt to try and clean the head and see if that will do any difference ? i mean to actually take it out... if it doesn't then will make no difference. i am also going to get new cartridges - do you think to get all of them ?

    Re: epson 7880 service manual

    not sure what you paid for this RAF but i spoke to a couple of people at work today, (had to go into the office for a van service)

    big chris who is the expert thinks its the head or a slim chance of the control board.

    he did say either way if you are capable of stripping the head out it would be worth soaking it in a bath of head cleaner fluid as you have nothing to lose. just make sure you mark anyhing thats being removed so you don't have to set head slant and so on when its been refitted.

    a grand for thats not a bad amount tbh, the heads going to be about £700 alone!


    because of the design you do need to immerse the head so a lot of solution is needed, maybe 5 kits to get the result and it could take a couple of weeks to disolve a blockage that bad.

    any idea on the history of the printer ?


    if you are commiting yourself then buy a pack of inks, your going to need them!

    a head change will use a lot of ink, you will need 10-15% to refill the head and purge it. the level of cleans i can access via engineer tools can flow 4x the ink to remove bubbles.

    Re: epson 7880 service manual

    i paid just over £2k for it, so there is some room to still make it sensible i suppose.
    with the cleaning solution, do you to put the whole head into the solution? i thought it is just the front face that needs to be immersed, as if the liquid gets inside it may damage/cause rust? of course forgive me as i don't know much about it
    do you know any good solution ? i think they are just diluted isopropyl alhohol, but maybe there is more to it. does epson actually sells them? i know there are some cleaning cartridges...
    i will get the cartidges, you're right, i am quite commited to get this printer working.
    i dont know much about this printer only that it came from company that closed down, it is not a printer that someone had problems with and because of that flogged it on ebay
    do you say it may be worth to try and push more ink before getting the head out?
    what still puzzles me is this pumps - is it still possible that the blocked head maybe causing their erratic behaviour ?

    Re: epson 7880 service manual

    i have little experience with those printers, the 9xxx is about as high (same but smaller) as i go and tbh i have never had to fix a pump issue. but they will kick in and out to keep up the pressure, the fact is you only have 2 playing up, if it was a pump issue you would have missing bits over all the colours and they would change each time you ran a nozzle check/ head clean.


    yes your right that certain solutions may mess up the insides, personally looking at a picture of the head i would sit it face down on paper towell soaked in solution and fill up the rear where the ink flows in so its attacking from both ends then seal in an airtight tub. i cant see it being just IPA as it would evaporate and cause a bigger problem if left unchecked as it would dry out the head when its evaporated so i would assume its a less solvent solution than just IPA.

    as its an 8k printer you would still have a damn good machine!

    And it turned out that one of the cartridges was leaking quite badly. I have bought replacement and....
    pumps don't go crazy anymore, are quiet, but the nozzle check is exactly the same.
    Another power cleaning to see if it will push any ink through, and another nozzle check - still exaclty the same

    indeed its probably a bit late to save the head, may be worth the cleaning solution as a last attempt.
