Replaced HP 88 Printheads, still receive same

This is an APA regulation failure. Not a good error. First you need to remove all the printheads and clean the contacts on the printheads and the contacts on the flex connector inside the carriage assembly that mate with the contacts on printheads. If no joy you need to perform the electronics test contained in the service manual link below. If still no joy then you need to replace all the printheads.

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

Hi,
As you said that you have already cleaned the print heads it could be the contacts inside the printer has gone bad. Its suggested by HP that if you get any error regarding the print head you should contact them and they will replace the printer. Please do so. Thanks.

Hello there, might I suggest downloading and installing the latest drivers for your HP Printer. It is all explained in my published guide entitled How to Install the latest drivers for Hewlett Packard Printer!!!

This may work, it may not work but it's worth a shot ey!

By installing the latest drivers we eliminate the possibility of a software bug.
Also if it is possible try install this printer on a friends computer/laptop. Another option is to try to clear the memory of this printer. Consult the manual of this printer.

A last resort would be to update the firmware of this printer, However when doing this be sure to install the correct firmware for your specific printer. Check the HP website.
Use cables to connect to this printer until you can get it working again, maybe the signal is corrupted if you use its wireless function! Just a thought!

Thanking you

Hello and welcome to FixYa!
In the HP OfficeJet Pro L7780 the printheads are actually separate from the ink cartridges. In your case, it sounds like the black/yellow head has worn out and will need to be replaced. The good news is, this is a user replaceable part. The bad news is, the replacement heads are not cheap. Amazon has the HP 88 Black/Yellow printhead listed currently for about $61.

YouTube has a nice video that explains how to install the printheads here:

I hope this helps!

take out printheads. unplugg power cable from back press adn hold down 6 and # buttons on pritner at same time while holding them down plugg it back in. then insert printheads one by one. first insert black/yellow shutt the door adn check for message on pritner screen. if it says printhead missing cyan/megenta it means it detected black/yellow printhead. do same with cyan/megenta adn check for message on screen. if you see no error mesage and both printheads were detected fine let the printheads alligned completely. then if u see same issue it is the pritner whgich need to be replaced.

that error show a problem with the pintheads
Remove ALL the Printheads and clean the flex contacts on the
Printheads and in the Carriage Assembly, if that dont solve the problem change printheads, if after that have the same problem call HP, was a hardware error.

try this link : I followed the directions and fixed the problem. the instructions that came with the new printhead weren't really complete.

Here's essentially all I did for my fix - Opened the printer top, turned the printer off. Removed the "bad" printhead, cleaned the metal contacts on the printhead and printer with windex. Closed the printer. Turned it on. waited for it to reset. Opened the printer. Turned the printer off again. Installed the printhead. Closed the lid. Plugged the printer in again. When it was ready I accessed the HP toolbox and alligned the printheads and cleaned the printheads. It worked. Here's a link with photos.

I don't just change the printheads, go to utilities and recover printheads.
If all printheads are playing up, che3ck the magenta cleaner, if it's over full it can cause all printheads to fail, this info was taken from a page on the HP web page, but ?I can't remeber where.

I updated the HP 9130 firmware and encountered the same problem. I turned off the printer, removed all the printheads and the cartridges, closed the printer cover and then turned on the printer again. After seeing an error message on the printer screen concerning the missing printheads, I opened the printer cover, replaced all of the missing printheads and the missing cartridges and then closed the cover. The printer then aligned printheads once as is expected after replacing the printhead and cartridges. Thereafter, it worked normally. I do not know why this procedure worked and if it will work in every case, but for now, it seems to have worked for me.
