Reset HP 970 Printers Cartridge

1. You simply ignore what the printer tells you. It will still work, but the out of ink message can be annoying.

2. Get yourself TWO other cartridges. Since the printer can only identify two cartridges at a time, it will have forgotten the first one by the time you move onto the third. Each time you insert the third cartridge, it will be treated as if it were never in the printer (i.e. the printer won’t recognize it).

3. You use the internal service-menu and manually adjust the identification.

Turn on the printer letting go of the power key, then push the power key and hold it in that position. With your other hand, you press the “FF” (Form Feed button, which has a picture of a sheet of paper on it) button, and / or the “X” button . The “FF” button is used for numbers less than 10 (-1, -2, to -9), whereas the “X” button is used for numbers which are a multiple of 10 ( 1-, 2-, 3- etc.). After you have pressed the “FF” or the “X” buttons the given amount of times, let go of the power button.

1 : Flower (head first)
3 : Alignment
4 : P/C, Page count
7 : Paper-indent-exactness?
8 : Never-ending Test (pages full of “H”s)
11 : P/C, Page count, Paper-sizing-dates
12 : ROM-Dump, P/C, Alignment-dates
20 : Simple cartridge cleaning
21 : Further cleaning
22 : Intensive cleaning (uses a lot of ink)
31 : Flower continued
41 : Cartridges-identification-dates / ink levels
84 : Nozzle test, like in the old HPs

4. You fool the printer, by covering over some of the contacts. Making the printer believe the cartridges are new: (Don’t forget to refill your cartridge before starting this method.)

  • Turn on the printer.
  • Open up the cover, remove both cartridges.
  • Place both cartridges in front of you so that you can see the contact foil, with the nozzles facing downwards.
  • With adhesive tape, cover the four upper contact points on the far left contact column of both cartridges
  • something like this: X . . . X . . . X . . . X . . . . . . . . . . .
  • Reinsert the two cartridges.
  • Close the cover.
  • Open the cover again after 2 or 3 seconds.
  • Wait until the printer gives you the cartridge carriage (If there seems to be a problem with either of the cartridges, ignore it)
  • Open the cover, remove the two cartridges.
  • Place both cartridges in front of you so that you can see the contact foil, with the nozzles facing downwards.
  • Remove the adhesive tape.
  • With adhesive tape, cover the four upper contact points on the far right contact column of both cartridges
  • something like this: X . . . X . . . X . . . X . . . . . . . . . . .
  • Reinsert the two cartridges.
  • Close the cover.
  • Open the cover again after 2 or 3 seconds.
  • Wait until the printer gives you the cartridge carriage (If there seems to be a problem with either of the cartridges, ignore it)
  • Open the cover, remove the two cartridges.
  • Remove the adhesive tape.
  • Clean the contacts well.
  • Reinsert the two cartridges.
  • Close the cover.
  • That’s it !!!

5. Test the ink levels (test #41) and align the cartridges (test #3).

  • Hold onto the power button, 4 * X (press “X” four times), 1 * FF (press “FF” once), let go of the power button
  • At the very bottom where it says “Remaining Quantities:”, 100% (or 99) should be stated twice.

Run the cartridge alignment, test 3

  • Hold onto the Power button, 3 * FF (press “FF” three times), let go off the Power button.

If you have used Method #4, your printer should now show that the cartridges are full and the annoying problem of getting the out of ink message should be solved, at least until you run out of ink again.

If you are doing Method #4, don’t forget to put ink in the cartridge first !!

    Useful post. I discovered a new way to trick the printer while I was working on these steps.
    Now there is no need to keep 3 cartridges. We can confuse/trick the printer with one cartridge only.

  2. Mathieu Gagnon says:

    These instruction make no sense for an HP 970 cartridge.

    It must be a guide for another model.

    There are 4 cartridge on an HP 970 and there are only four contact no column like ,,,

    “the four upper contact points on the far right contact column of both cartridges”

    Actually it is for very old PRINTER MODEL HP 970 not Cartridge HP 970
