I found the following here:

"21 I ran your hpfix.exe patch for my K850 printer, and though it
found and modified the driver file, it did not change “SET TIMESTAMP”
to “SET TIMESTAMX” as in your notes…it changed another byte in a very
different location. Thankfully, your [R]estore option worked to put
things back the way they were. Then I used a binary editor on the same
driver file (Hpz3r42i.dll), and manually changed “@PJL SET TIMESTAMP”
to “@PJL SET TIMESTAMX” as in your notes, restarted, and now it works
fine — no more ink expiration errors! Thanks!
[HP tech. support & mgmt. was absolutely a waste of time on this -- no
respect for even good customers. Will avoid all HP in future.]"
Apparently the complicated fix didn't work but editing the timestamp
file does.
Worst case, if it goes sideways on you, you can always use the
"Restore" option, but you're back to square one.
Some claim that you can power down and disconnect the printer, reset
your PC clock, then reconnect and turn on the printer to fool it into
thinking the cartridges are younger than they really are.
I have not tried any of these tricks; I quit using HP printers a
couple of years ago.
Good luck!
