HP Photosmart C7280 Ink system failed

[CWAG]

Yes as a matter of fact I replaced all the inks - could have bought a new printer for less. I have since managed to get it to print different colors but not the colors that are called for?

Thanks to the HP employee, this trick fixed my printer. THANK YOU!!!

Thanks, Ciara!

I had to swim a little around in the menu structure that popped up, though - it did not display as you mentionned in your advice, but - at last I found an entry in the menue that allowed me to set the printerheads to "Clear" or "Set" (?). I selected "Clear", and from that point, I could exit the menu & the printer worked.  It took me about 30 minutes, checking out each corner in the menu structure (just for the kick of it)- but there was a lot of info to obtain from it, so it was well worth it.

I know, I know....  why bother at all, when a new printer is so inexpensive (and a lot mode advanced today, I bet).. but you have this C7280 printer already standing there, and I will rip it to atoms attempting to fix it rather than just dump it... call me cheap.. but I have an operative printer. again. 🙂

Semi-full reset
This will reset the All-in-One to the factory default settings by using these instructions:

1. Unplug the power cable from printer while the printer is powered on.
2. Press and hold Plus (#) and 6 while plugging in the power cord.
3. Repeat steps one and Two, Two more times for a total of three times.
This will perform a maintenance cycle upon the third restart.

Now you may want to print a self test report by pressing "Setup" and then 1, then 1 again. or Clean the heads by Pressing Setup > 5 > 2  



OOB NVRAM RESET  (Remove Air in Hydrolic lines)
1. Turn Power off using power button.
2.  Hold down the CANCEL & OK buttons & keep them held while powering on the printer.
Keep them held till the printer shuts itself back off. (It will shut off without you hitting the on/off button.)
3.  Then power it back up normally by hitting the on/off button. It will warm up normally except it will display a message "OOB NVRAM RESET" & it will then do about 3 minutes of priming & pumping up the ink in the tubes that run from the cartridges to the print head.
4. You then can run a test print in the tools section.
YOU MAY HAVE TO DO THIS PROCEEDURE AS MANY AS 6 TIMES.  IT WILL EVENTUALLY GET ALL AIR BUBBLES OUT OF THE SYSTEM.


Semi NVM Reset
1. Unplug the power cable from printer while the printer is powered on.
2. Press and hold the (#) and 6 buttons while plugging in the power cord and keep both buttons depressed for at least five seconds.
3. Printer will shut off
4. Press Power on and unit will begin the Semi NVM reset.
The unit will clean its heads and the pump will cycle several times to prime the hydrilic lines and purge out any air.
Then a Maintaince cycle will begin.
