Ink Levels Reset for HP Cartridges HP21, HP27, HP56, HP58
This reset methode be used to reset ink levels for hp cartridges HP21, hp27, hp56 and HP58 (On most models). I have tested this reset methode and work perfecly but in the some printers model this reset methode does not work.
Here the Ink levels reset methode for HP cartridges HP21, hp27, hp56 and HP58:
- Remove cartridge from your printer.

- Place a piece of tape over the top left contact as shown in red on the picture to the right.
- With the tape covering the contact place cartridge back into printer.
- The printer will perform and alignment page. (Some newer models no longer print alignment pages. If printer runs through a series of priming routines and stops for 20 seconds continue through with next step.)
- Once an alignment page has been printed remove cartridge from printer.
- Place a piece of tape over the second contact shown in red.
- Place cartridge into printer with both pieces of tape. (One covering the first contact and one cover the second contact.)
- Printer will print another alignment page. (Some newer models no longer print alignment pages. If printer runs through a series of priming routines and stops for 20 seconds continue through with next step.)
- Once the second alignment page has been printed remove cartridge from printer.
- Remove tape pieces from cartridge contacts Make sure there is no residual adhesive on cartridge contacts.
- Place cartridge into printer. Cartridge should now read full.
Additional Notes:
As stated above it is very important that there is no residual adhesive on the cartridge contact point. This will make reading the cartridge difficult.
If for some reason this does not work for you then you will need to repeat this process. If you have to reattempt the reset please turn computer off before doing so. Leave computer off during the reset process

This is primitive solution. Try full reset without any tape shit.
Turn off the printer and unplug power cable from the rear.
Then press and hold On and Cancel buttons and plug the power cable. Release both buttons only after any leds stop blinking. Printer will do full reset, and ink level is 100%. Simple.
Bingo, it worked! Thanks so much for the solution.
I have several printers from different manufacturers, and they all have their sneaky little tricks to get you to buy their cartridges. I do my own refilling……….
