Hi,
Odd issue with my HP 500 - if I try to print anything it stops printing yellow during the print. The print carries on as normal to completion but no yellow after about 9 - 12 " of whatever I am printing.
I have changed the cartridges and changed the printhead but no change. I stripped down the ink station and cant see any issues. I have even tried purging the tubes but still the same.
I am thinking maybe a leaky seal so new ink tubes required - anyone got any suggestions please?
Thanks
Darren

any color missing & messed up whole image.
You can find a syringe/injector, use replace printhead option & move the carriage out.
unplug the power cord. remove yellow printhead & insert syringe needle into the center of nozzle,
slowly draw out ink, I am sure you will see bubbles, draw till solid color. do the same for other colors.
clean contacts & insert printhead back & power on. perform a printhead alignment.
Good luck.

Last december, I bought 2 set of #11 printheads from China on Ebay, really cheapy... $42 a set of
4. all working perfectly.
Most seller selling way outdated printheads, like 2007 etc.. all empty.
For hp genuines, those dark color box with cyan butterfly , dated about 2013 or later ok...
good to have a good set for spare.....do not leave it idle for too long time. do a color alignment vey few days
