OK, slap my wrist, I was a Bad Boy. . . .
I tried to refill exhausted print cartridges on my OfficeJet 6500 - and had no end of troubles. Yea, I know. Brainy move Einstein! One of the recommendations was to turn off chip ink level monitoring via the preferences menu (#7) within setup.
As I am sure you can guess, that didn't do diddle-squat, so now I want to go out & get some genuine HP cartridges. Before I install them, I want to undo the mess I made and put things back the way they were.
Question: How do I turn that option back ON? Having turned it off, the option has totally disappeared from the preferences menu altogether.
I tried a "Reset Defaults", but that doesn't work. Is there a way to turn it back on? Absent that, is there a way to, (so to speak), nuke the printer back to the Stone Ages so that it's back to it's Out-Of-Box state?
This question was solved. View Solution.

I figured it out!
To accomplish this, you need to do a NVRAM Reset by performing the following sequence of steps:
- Turn power off to the printer using the power button on the front panel
- Using two fingers on one hand, press and hold both the "#" and the "6" keys at the same time.
- Using the other hand, press the power button to turn the printer back on.
- Continue to hold the # and 6 keys until the display goes blank, and then lights back up again. It will then say "Semi NVRAM Reset" - at that point you can release the # and 6 keys. This might take a minute or two.
Once this is done, the printer will go through its "out-of-box" initial set-up routine for printing. That is, it will attempt to re-charge the print-head by performing multiple cleaning cycles and will then run an alighnment cycle.
At that point you're done.
Hopefully that helps.
