laserjet 4050n will not go into service mode

[PC Doctor]

:D Hi,

I have put a fuser and roller kit into a 4050N and I can not get it to go into Service mode to reset the Preventative maint. count. I have tried the short cut and what was listed on the printer tech page. Any ideas?

Thanks

Never Mind I figured it out. THanks :) :D

Here is the quote from the HP 4000/4050 service manual.

Mind you they are not always correct, but in this case I believe it is.

"Reset Maintenance Count
After the PM kit has been installed, reset the maintenance count.
1 Turn the printer off.
2 While pressing [– Item] and [– Value] turn the printer on.
RESET MAINTENANCE COUNT appears, followed by INITIALIZING.
After a few seconds READY appears."
