Bought this "genuine" cartridge thinking it would not be a problem at all (I also used the cartridges from that big auction site - but needed a new chip as the old one stopped working).
Installed this and first thing I know the printer starts throwing an error+asks me to take out the cartridges and install them again.
I opened the printer door and took out the cartridge and it was leaking all over.
After half an hour of wiping the printer, the printhead then washing my hands, I try to install it again and same thing.
Call Amazon, as usual they were amazing, and it's on it's way back.
*** Never *** again a HP printer (check my other review), TYVM.
