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.
Other solution is to change the time in windows and restart the computer. This fixes the problem, but also you cant have all the time the windows time changed years ago.
The other way is to hack the drivers. I searched all over the drivers and i found i have to change hpj3r589.dll which is C:\\WINDOWS\\system32\\spool\\drivers\\w32x86\\hpofficejet_pro_k5404d7a
I then opened the file hpz3r589.dll with a hex editor (xvi32) find @PJL SET TIMESTAMP
And replace it with this, misspelled with X at end:
@PJL SET TIMESTAMX
Make no other changes. Save it, turn off printer, restart.
Hope this saves you time and money ;) I spent 5 hours for all this :) But now i feel very proud :)
