Hp Pro K5400: bypass cartridge expiration date
I searched all over the internet and i didn't find a complete solution for this model when we have the error regarding the cartridge expiration date that make's our printer not to work.
The solution in other HP models is to remove the battery. I opened with a lot of difficulty the printer but i didn¢t found a battery in order to remove it and reset the internal clock. If there is any, it should be behind the inks in the left side. I searched in the right into the circuit but i didn¢t find anything.
