20 Most Recent HP Officejet Pro L7580 All-In-One InkJet Printer - Page 2 Questions & Answers

Try doing running it through it's aligment process.

It is also possible that the contacts where the ink cartridges mate up with the printer are corroded. Try using an eraser to clean the corrosion off the mating surface in the printer.

I have serviced an officejet pro L7580 which was showing a paper jam error when powered on. our customer had had a paper jam and removed the paper . I found small peices of paper in the pick up assy gears. If you remove the rear door, you need to check the 2 small white gears on the left. turn the roller slowly by hand and clear any paper stuck between the teeth. (they may be very small).

after doing this....no more paper jam errors for me!

Introduction There are times when a partial reset may be required to restore the HP All-in-One to proper operation. A partial reset does the following:

• Reset the user settings to the factory defaults.
• Reset the language and country/region settings on some models.

Performing a partial reset

1. Unplug the power cord from the HP All-in-One.
2. Wait for 20 seconds.
3. Press and hold # and 3 while plugging in the power cord to the HP All-in-One.
4. Release the buttons after the HP All-in-One starts up.
5. The HP All-in-One will now be reset to factory defaults.

Thank you so much.

It's probably a problem with the black/yellow head.
lift the topup to access the heads. if the heads don't move over to the change station area (all the way left as I recall for that unit) press and hold the * until they do.
lift the big blue flap, then the blue handle on the black/yellow head and pull straight up to remove it.
Take a q-tip dampened with bottled water (dampened, not dripping) and clean the CONTACTS area (not the HEAD, just the little round/square copper pads) on the printhead, and disconnect the power from the printer, and clean the printhead contacts in the printer as well.
Without reinserting the head, close up the head access blue flap, and close the printer lid
press and hold the # and the 6 on the keypad. While holding these, reconnect the printer power
wait for a RESET message of some form to appear on the screen, or for the printer to shut back down.
If the printer demands you replace the damaged/missing head, put the printhead back in at that point, but not unless the printer is asking for it!
Once you have released the buttons, turn the printer back on if it shut itself back off.
put the printhead back in when the printer asks for it, if it hasn't already.
The printer will now go through several minutes or whirring and clicking and so forth. Let it.
In the end, it should produce a calibration page.
If the black prints ok, you're done.

If not, you'll heed to replace the black/yellow (K/Y) head.
You can usually get them where you get your ink.

Do you use original HP cartridges?

it is better to buy a new printhead 
it is very difficult to cleaning it with out
professional equipment (that very few have) 
you can refill it from the down site of the print head
by putting in the plastic ball that has
after filling it you must close it with hot glue
but i insist that i can not guarantee for the result

You will have to reset the printer.If you want any further support, a technician from techbuddies can help you for free.For this log on to www.techbuddies.org

The black print head has a few blocked nozzles. Inkjet printers need to be used frequently to prevent ink drying out and blocking the print head nozzles. If the print head cleaning maintenance routine does not clear the blockages, then print head needs replacing, but it may be expensive. It may be more cost effective to buy a later model and better printer than replace the print head.

I had the same problem. Ended up replacing the black/yellow "printhead" and that corrected the 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.
