Trust me you can change your own X900 printhead all by yourself, with the very detailed and thoroughly explained help of this video.  You will need a servprog.exe file to sync your new head, I can help with that.  I used to do all this for donations, which only about 2% of users offered in return.  To those who responded by donating, I thank you sincerely.  To everyone else I am happy you are up and printing again.

That was the past, this is the future.  Rent this video for $45, save yourself $1,000 (sometimes more), and email me with any questions you like.   You get the video for 30 days, you get the appropriate servprog.exe program for your machine, you get my email support (which you will not need if you follow the video as patiently and thoroughly as I created it for you).

As for what you are up against changing your head, Epson will sell you a replacement head.  All you need to do is install it.  This video shows you how, one step at a time.

Note*:  the final step of your new head install will be registering the numbers on the head to the printer, using a PC-only program called “servprog.exe”.  It is rare but some people have had problems with the software not recognizing the printer due to them using an incompatible windows version.  If this happens to you, here is a solution from a fellow Epson head changer, David Lorenz:

Set up Oracle’s Virtual Box VM (virtual machine) on windows pc and install in the VM, Windows XP32 bit.  Then install the driver for the printer in the VM copy of Windows XP.  Print nozzle check to be sure printer is installed OK.  Turn off printer and turn back on in serviceman mode.  Now install Servprog.exe in the VM Windows XP and run.  This worked for me.….  David”

Good luck my friends.

  1. Hey Eric,

    Do you know if I can put an Epson Stylus Pro 7900 print head into an Epson Stylus Pro 7700?

    Thanks!! Wayne

      Looks like you can from what I can gather researching parts lists online, but I’ve never done it personally

      • Wayne Erickson said:

        Hey Eric,

        Thanks for the reply!!!

        Well I have a 7900 and 7700 to give it a go with. The only thing is the 7900 just started to give me a FATAL ERROR FatalError ID : 1A39, it was printing fine before the error.

        I am attempting to clear the error if I can.

        Thanks again!! Wayne

    Any chance this will work on my clogged-up P8000?

    • Eric said:

      I’ve had two people use this for that machine. I even bought the program and gave it to them. While they were successful, though, I can’t say 100% personally because I’ve not actually done it with my own paws.

      • Mel said:

        I think I’m one of those two Eric referred to. I successfully replaced the head on my P9000 a couple years ago. I’m very grateful to him for providing the new service program for us, but there are some critical things you need to know before attempting to use it:

        BEFORE launching the program you MUST set the clock back on your computer. I know that March 10, 2018 works, so I use that date. If you don’t, the program will say it’s expired, and then no amount of changing the clock will help you.

        The activator program is a little confusing, but here’s how to use it: You click on the text that says “Drag me” and drag it over onto the grayed-out “OK” button on the service program. The “Text” box on the activator should then show a hexadecimal number followed by a hyphen and “OK” (such as “0040B70 – OK”). You have to click on that text and then click the “Enable!” button, whereupon the “OK” button of the service program will become clickable.

        This is excellent Mel. Thank you so much for sharing your knowledge and experience!

    Тhe head need to be calibrated after a change?or just run a head cleaning

    • Eric said:

      If you follow the manual the answer is yes, you need to calibrate a new (or changed) head. But the manual also says you have to set the timer on a new wiper blade, which you do not. I have changed heads without calibrating them, during testing, and they worked the same.

    • Changed mine months ago, never calibrated, working fine

        after inserting what should be done

  6. Thanks for the video/help. I was able to resolve the issue on my 9890. I will admit it took a little more effort than expected, and I assume it is my own fault. Back story, my printer was converted to run dye sublimation ink about a year ago. I changed out the ink switching unit which includes the dampers. The instructions stated to change the rubber gaskets between the ink tubes and the ink switcher, due to the fact that I did not have them at the time, i changed them now when changing the head. I am assuming this introduced air into the ink tubes before the damper, which caused more of an issue. After running a cleaning cycle, I seemed to have all the channels firing, but then the yellow dropped out and eventually the vivid magenta. I had run a power clean and several unclog print jobs from Qimage and then pair cleaning, not making
    any progress. I eventually ran an ink charge and that resolved the issue.

    Thanks for the help!

    Hey Eric and thanks for the video, I removed my epson 9900 print head and put it back again but I can’t print anything, it says it’s printing anything but doesn’t actually print anything, I tried to do the Init Fill but nothing seems to work, any suggesions?

    • Eric Gulbransen said:

      Are you sure it’s filled with ink? Air = no pressure = no ink

      • ioan said:

        i fixed it by doing cleaning int clean 1-3 after reseating the cables and it’s working properly

      • Eric said:

        Nice work and thanks for sharing Ioan

    I have an Epson 7890 and it needs a new head. Is there any specifics missing for me following your guide on this printer as its very close to the 7900. Do I need new software tool or firmware that you have not got a link for?

    • Eric said:

      You can use this video for 9890 head swaps. Many before you have. And I do have the software for the 9890 which comes with the rental. Email me after you rent the vid. I’ll send you some other helpful stuff too.


  9. Larry Chapman said:

    Hi Eric,
    watched the video, head is on it’s way, where do I get the servprog for a 9890?

    • Eric said:

      Email me directly following the link on the site and I’ll hook you up Larry.


  10. Vani Thatcher said:

    Hi, do you still have the ServProg for the Pro 4900?
    Could you please send it to me via mail?
    Thanks in advance

    • Eric said:

      Unfortunately I don’t have the program for the 4900. Different animal. I think because the machine costs less, when the heads go people replace the whole machine instead of just the head like we do on the bigger machines. Sorry I couldn’t help you.

    Hi Eric
    I have an Epson Stylus pro 9900, and I believe that the print head is bad. ( lots of cleaning, maintenance cleanings, Magic Bullet… matte black nozzle check is not changing at all, nozzle patten is almost blank.
    so the next step…can I do this ..? decided. to try, but now it seams that I cannot purchase a new print head from Epson? can you (or anyone) advise please?

    • Eric said:

      Chris, first of all why can’t you buy a head from Epson directly? Second, I just helped a guy do a head change on an 11880 and he bought the head in an “unopened box” off ebay for $1,400.00. He just pinged me Friday night to say he’s back up and running successfully. So Epson direct is not your only option, but it is a reliable one. Curious why you can’t buy from them directly.
