Just bought printer tonight. After assembling and cutting the power on, got an error message that the Black/Yellow printhead had a problem. I don't know how to take the printhead out and reinstall. Please help!
Since it's brand new and it doesn't work right, take it back for a replacement.

To print the print quality diagnostic page
Use the print quality diagnostic page to diagnose issues affecting the print quality. This
will help you decide whether to run any maintenance tools to improve the print quality
of your printouts. You can also view the ink level information, and the printhead health
status on the page.

quality) diagnostic page and follow the onscreen instructions.
• HP Printer Utility (Mac OS): Click Print Quality Diagnostics from the
Information and Support panel.
To align the printheads
Whenever you replace a printhead, the device automatically aligns the printheads to
ensure the best print quality. However, if the appearance of your printed pages
indicates that the printheads are misaligned, you can start the alignment process

To clean the printhead contacts manually
After the printheads are installed, you might get a control panel message telling you
the device will not print. If you receive this message, you might need to clean the
electrical contacts on the printheads and in the device.
CAUTION: Clean the electrical contacts only after you have attempted to clean
the printheads. Electrical contacts contain sensitive electronic components that can
be damaged easily. For more information, see To clean the printheads.

2. If the carriage does not move to the left automatically, press and hold the OK
button for five seconds. Wait for the carriage to stop moving, and then unplug the
power cord from the printer.
CAUTION: Do not use water
6. Wipe the electrical contacts on the printhead but do not touch the nozzles.
NOTE:The electrical contacts are small copper-color squares, grouped on
one face of the printhead.
The nozzles are on a different face of the printhead. Ink will be visible on the
nozzles.
CAUTION:Touching the nozzles can cause permanent nozzle damage. Also,
ink can permanently mark clothing.
7. After cleaning, place the printhead on a sheet of paper or paper towel. Make sure
the nozzles are facing up and are not in contact with the paper.
8. Clean the electrical contacts in the printhead slot inside the device with a clean,
dry, soft and lint-free cloth.
9. Plug in the power cord and turn on the device. The control panel should indicate
that the printhead is missing.
10. Insert the printhead into its color-coded slot (the label on the printhead must match
the label on the printhead latch). Press down firmly on the printhead to ensure
proper contact.
11. Pull the printhead latch all the way forward, and then press down to ensure that
the latch is properly engaged. You might have to apply some pressure to engage
the latch.
12. Where necessary, repeat the above steps for the remaining printhead.
13. Close the top cover.
14. If the control panel message remains, repeat the cleaning procedure described
above for the printhead which corresponds to the message.
15. If the control panel message remains, replace the printhead which corresponds to
the message.
16. Wait while the device initializes the printheads and prints the alignment pages. If
the device does not print the pages, start the alignment process manually. For
more information, see To align the printheads.
Any luck?

If the new printer is showing error message you can try reinstalling the print head and check if it still does not work.just get it replaced as if the head gets damaged physcially they will charge you for new replacement head. just take care of that
thanks.
Just take it back and say its messed up. Its not worth the trouble if its brand new under warranty.
You did take the thin plastic film off the ink cartdridges before putting them in right?
Just asking because this could cause problems.
In this case what i would request u to do is.......
Take out both the catridges from the Printer.........
Take 2 Paper Towels one should be wet with Luke warm water and the other one should be dry...........
Take the Colour catridge first turn it upside down and u will see a small copper plate on the catridge from where the ink comes out.......
Place the wet paper towel using ur thumb on the Copper plate and press it a lit bit for 10 Seconds......
Now remove it and see whether u see any ink on the paper towel..........
U should see some ink on it now place the dry paper towel on the ink catridge in the same way........
Now do the same procedure again..........
Do the same procedure twice on the Black Catridge.................
Now take the dry paper towel and turn the direction of the cartridge so that u can see a Copper plate on it with small boxes just clean that copper plate with the Dry Paper Towel..........
Know insert both the catridges inside the Printer.....
Good Luck

Hi....If this is the first time the error has occurred, try turning the printer off and on.
Let it sit turned off for at least 20 seconds before powering it back on.
If powering off and on the printer clears the error, please continue using the printer but watch it to see if any printhead errors return.
If your printer continues to display a Printhead Error message, make sure it is plugged straight to the wall and not through a surge device or power strip. Power strips and uninterrupted power supplies can cause a low amperage problem in your printer. This can trigger a printhead error even if the printer has worked on this surge device for months.
If the printer continues to post a 930 Printhead Error, it thinks the wrong printhead unit is installed.
If the printer was recently serviced, make sure the correct parts were used. This is especially true if the parts replaced were either the printhead unit or the printer's engine/system board. It is in one of these two parts that the printer is detecting the problem. Note: If you are the person repairing such a printer, please be aware that parts from different, though similar, printer models may not be compatible with this printer. Also make sure to check the laser cable going from the printer's engine board to the printhead unit, as it reads that signal.
If the printer was not recently serviced before this error occurred and powering the printer off and on does not help, the printhead unit and possibly the laser cable or the engine/system board to this printer may need to be replaced.
If the printer continues to post a 931 Printhead Error, it thinks there is an error in the signal going to the laser or the Hsync part of the printhead assembly.
If the printer continues to post a 932 Printhead Error, it thinks there is an Hsync error occurring in the printhead assembly.
If the printer continues to post a 933 Printhead Error, it thinks there is a failure in either the Hsync signal or with the mirror motor unit of the printhead.
If the printer continues to post a 934 Printhead Error, it thinks there is a "lock" failure with the mirror motor assembly within the printhead assembly.
If the printer continues to post a 935 Printhead Error, it thinks the mirror motor unit within the printhead unit cannot reach its operating speed.
If powering the printer off and on does not clear any of these errors and it is already connected directly to the wall, your printer may require service. It could have a defective printhead unit or there might be a problem with the engine board or one of the printhead cables. Note: If you are the person repairing such a printer, check all of the cables going from the printer's engine board to the printhead unit for any damage. Also check the continuity across these cables.
thank u.... reply

The Printer is an HP Officejet Pro L7590 that I am getting a printhead error message. How do I take out the printhead and reinstall. The Black/Yellow printhead is the one with the problem. Brand new printer, just bought today!
This is a brand new HP Officetjet Pro L7590 printer. Just out of the box. I tried turning off and back on and that does not clear the problem. Can I take the printhead out and try to re-install once it has been installed inside the printer.
