HP Officejet Pro L7580 All-In-One InkJet Printer - Answered Questions & Fixed issues

try unhooking from computer and wall
and hook up again

On this HP the print head is not part of the cartridge. How do you know the print head is fine? Did you just try to do a test page without an alignment? I know that HP (they suck) will not help you because you are past warranty - Google your question since I am sure that you are not the only person to have experienced this issue. I think you have a bad print head.

Two choices; 1. Take the machine apart and take the roller out and then bend back the little follower. 2. Break the offending follower off and hope the paper still feeds through OK.

get rid of that hp piece o crust. demand your money back.

My HP printer has a cleaning programme and a cartridge priming programme. I had trouble with my colour cartridge, in particular the cyan. The cleaning cycle never worked but the priming programme worked a couple of times but whenever the printer was left idle for a while the colour would not print. I took the cartridge to a refill shop and the guy emptied the ink and steamed out the cartridge and print head and refilled it and then it did work for a time. A new cartridge is expensive and so these days I just use it for printing black... I think there must be something strange or different about the cyan ink. Sometime in the future I am going to try steaming again only this time with a deal more pressure than the guy at the refill shop used. I am sure it will be kill or cure... Deleting the printer and reinstalling it should be the next step to try. Sometimes my printer goes a bit eccentric or gets in a bad mood if I try and pause or cancel printing from the printer menu. I have learned not to do that with any HP printer. Once it gets in a bad mood the only cure is to disconnect it from the mains and leave it for half an hour before plugging in again. My printer, incidentally, is a Deskjet 96 Cxi professional machine. I like it because it prints both sides of the paper and it cost me nothing.

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

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.

HP88 CARTRIDGE RECOGNITION FAILURES/CAUSES: The failure to recognize an ink cartridge(s) could either be a possible Cartridge connectivity, PRINTHEAD* connectivity or an end-of-life PRINTHEAD issue. We suggest you remove all the ink cartridges and thoroughly clean BOTH PRINTHEADS manually along with cartridge chip contact surfaces (located on bottom-rear side of each ink cartridge). Clean all electrical contacts, including those inside the printer which mate to the PRINTHEADS. Reinstall both PRINTHEADS and cartridges and retest. You may refer to HP's 'manual' cleaning procedures here: http://h20000.www2.hp.com/bizsupport/TechSupport/Document.jsp?lang=en&cc=us&taskId=125&prodSeriesId=2511747&prodTypeId=18972&objectID=c00844045 Ensure an "expired ink cartridge" alert state is not causing the issue, refer to this page on how to check & bypass: http://inkjet411.com/?page_id=1384 ---- If you observe an "Expired xxxx ink cartridge" alert or message, this error may be bypassed by performing the following: a. Press and HOLD the Power button. b. Press Resume button 3 times. c. Release the Power button If the cartridge was refilled (i.e. at Costco or Fry's Electronics), following HP 88 cartridge chip replacement and complete cartridge/printhead/printer manual electrical contact cleaning, the cartridge alert message(s) continue, then you may have a damaged PRINTHEAD* (there are two printheads inside the printer) which may require re-priming or replacement depending on problem symptoms. * The HP 88 ink-series printer models have two electronic PRINTHEADS (each of these electronic devices are responsible for pulling ink from the ink cartridges and then firing the ink droplets onto the paper) - both PRINTHEADS will eventually fail depending on printed content, printer duty cycle (i.e. typically rated for ~41, 500 printed pages depending on image content & frequency of printing). The average inkjet printer can typically be refilled with ~15 to 20 complete sets of ink cartridges over the life of the printhead, after which, either the Yellow/Black and/or Cyan/Magenta printhead will need to be replaced due to internal electrical failure (available at HP.com). Refer to video on how the HP PRINTHEAD functions: http://inkjet411.com/?page_id=2054 When the PRINTHEAD electronically fails typically the printer will provide an alert message when this happens, but if a printhead has suffered a deprime (i.e. loss of ink/pressure which results in no printing of color), it is possible to recover the system using a 3rd party PRINTHEAD priming tool, such as this one: http://www.inkowl.com/?p=product&product=5035 For advanced HP printer diagnostics or information on ink refilling services, please visit Inkjet411: http://www.inkjet411.com

Try resetting. Unplug power for a few minutes and restart. Failing that, try troubleshoot from the manual instructions.

Simple solution is:

Replace the Black and Yellow Print Catridges. The print heads are mounted to the bottom of the catridges and these, depending on whther they're from HP or not. can have a hard time conducting electricity properly, and in turn.. spitting ink out properly.


Also happens often with aftermarket Catridges because HP puts chips on the catridge. be sure to put an HP catridge. Sometimes you get what you pay for :)
