Only solution to this one (and I know) buy another printer. I had this problem a couple of years ago on an earlier HP Officejet and the solution given was to spend about $200 less to have it fixed than it cost; made it more beneficial to go out and buy a new one as the new ones cost a lot less than they did a year or two ago (plus this gives you the warranty). "thinks: Seems that all these problems happen just after warranty expires - ah wel......"


One of the most common events for this appear to be during change of cartridge(s) for the printer.

Hope this has helped somewhat

    I had the same problem and resolved it. Hewlett Packard does not provide a manual with the HP Officejet Pro L7590 printer that is good for problems solving. I found a company called 123 injets (website www.123inkjets.com) and ordered a new black and yellow printhead (about $75.00) for my computer rather than buying a new printer like their support person recommended. I made the mistake of not going online to get directions on how to install the cartridges and the printheads and just put them in with the printer turned off. It is supposed to be 'ON' and then it runs through its cycle to make sure everything is working right. The last step will be aligning the printer. You need to make sure that the printer is ON and the blue carriage is over to the left side when you install the printhead. Then let the printer run its' cycle for checks which may take some time. It will automatically go through the aligning of the printer as the last step and it should print out 2 pages with a bunch of colors on the pages. It will then say that the alignment was successful. HOWEVER, if you made the same mistake that I made this will not work. I installed the cartridges and the printhead with the printer "OFF'. AND I had picked the black cover off the printheads on the RIGHT SIDE and replaced the printhead there. I kept getting the message about something being wrong with the black and yellow printhead. To resolve the problem, I do not remember the exact steps that I went through but I put the OLD printhead back in and took out the new one. Do not remember if I put it in on the Left SIDE, or on the RIGHT SIDE under the black cover but I was able to get the printer to run its' cycle with the OLD printhead in place. At the end of the cycle, the 'alignment failed' message came up and only a small amount of the first page of the two pages for the alignment was actually printed. This is because the white horizontal streaks that I had with the OLD printhead were there and the checking system detected the problem as it should. At this point, I believe that I pressed the "OK" button and opened the top cover to access the printheads again. HOWEVER, rather than having the blue carriage off to the LEFT SIDE, I kept it on the RIGHT SIDE and popped the black cover off that is over the printheads and I replaced the OLD printhead with the NEW printhead while it is on the RIGHT SIDE. Then I closed the blue latch and then the cover. THEN, I went to the SETUP button and TOOLS and then under TOOLS, I put the printer through the align printer cycle manually by pressing on that. It went through the cycle and successfully printed the the two alignment pages this time BECAUSE the old problem with the old printhead was gone and the new printhead did not print the white horizontal streaks. I was much relieved and the printer is printing fine now. Good luck---just keep playing around with it and I think that you will get it to work. I do not think that you need a new printer.

Same thing happened to my printer hp L7590. Printed diagnostic, only black and yellow printed; diagnostic for printhead health Ky=good, MC= good. Only Hp products ever used. Uplugged, & discharged static, cleaned copper parts of printhead. Still no fix. On visual examination of floor of printhead compartment rectangular pad ( approx 1/4" by 1/2") is missing. I can only guess that during the paper jam, somehow the pad got caught up and went awol. Not sure what to do now.

My office jet L7590 printer suddenly quit on me. It keeps playing a message that says the printhead has a problem


Did you let one of your inks run dry? If so, you need to replace the effected printhead. This model has two, one for black and yellow, and a second for cyan and magenta. If you let the yellow run dry but have tons of black, it still effects the black/yellow printhead. Same with the other, either color going dry makes its printhead go bad. Either printhead will set you back about $75. Easy to remove and replace once you get the new printhead.

Bottom line with this model of printer...DON'T let you inks run dry. A new ink cartridge is $20 vs. $75 for a new printhead.

FYI - This is the most common mistake/problem with this printer. The Inkheads are built to last at least 40,000 prints. That's several years for most of us, that is unless you let the inks run dry.

Officejet Pro L7590 printhead message (printheads only 2m. old)!


Pull out the printhead from the computer and check the date under "warranty ends" If the warranty period did not lapse, call HP technical support and tell them about the problem. They will replace the printhead for free. I have gone through 3 black/yellow printheads and I received the replacement printheads via FedEx within 1-2 days. They will send you a pre-paid envelope to return via U.S. Postal Service via US Postal Service.

If the Warranty date on the printhead expired, then you may have to come out of pocket to replace the printhead since HP will argue that they are not obligated to replace the printhead since the manufacturer warranty lapsed.

If this is the case, check to see when you purchased the printer. If the purchase was within a year, the retailer (i.e. Best Buy) is on the hook since there is a 1 year implied warranty on products such as printers, regardless of whether the expiration date on the HP printhead expired.

Hope this helps

My HP officejet Pro L7580 says the printhead has a problem


Re-insert the print cartridges. It is also possible that the heads are burnt. Get a new set of print heads (black/yellow) and install to the printer. If problem persists, clean the contacts on the printers. Use acetone + cotton swabs.

Changing the printhead


FYI: The L7590 doesn't have any tape on either the cartridge or the printhead.

Right couple of things here...

1. The printheads in the L7590 are either K/Y (black/yellow) or C/M (cyan/magenta)... There's no single black printhead unless of course this is not an L7590 we're discussing here.

2. The cartridges ARE individual with K, Y M C (Black, Yellow, Magenta and Cyan).


It's likely that the printer has one of the following faults.
  • Chip contacts and/or chips on the cartridges are soiled and/or damaged. Try checking for ink on chips and contacts in the cartridge bay

  • The little white oval pump in the bottom of the cartridge bay has become disconnect or broken. This is used by the printer to pump ink into the printhead but it also detects pressure variations and has a logic circuit which declares low pressure as "no ink".

If the problem is the latter then you need to get the printer serviced and/or repaired at a service center.

If it's the former you should be able to fix it yourself.

If you're using non OEM (ie: not by HP) cartridges I'd recommend getting a new OEM/HP one to test before you go for a service as some cartridges are just poorly filled and/or designed.

Hope that helps.
