How to Reset an HP Inkjet Cartridge

Step 1
Insert the cartridge you refilled into the HP printer. Have the printer print an alignment page, thus recognizing the cartridge. The printer will still read the ink level as where it was before you refilled it.

Step 2
Remove the cartridge from the printer and replace it with another old cartridge. Have the printer print an alignment page with this cartridge so it recognizes it as a different cartridge from the first one.

Step 3
Replace the second cartridge with a third one and run the same alignment page. Because the printer only retains the memory of two print cartridges, it will erase the memory of the first (refilled) cartridge.

Step 4
Insert the refilled cartridge into the printer. The printer will now recognize the cartridge as being full.

Step 1
Tape over the contact squares on the top left corner of the cartridge's contacts. Insert the cartridge into the printer and run an alignment page. Ignore any messages that might appear saying there is a problem with the cartridge.

Step 2
Take the cartridge out of the printer. Remove the tape from the left corner and tape over the contact squares on the top right corner. Place the cartridge back in and run another alignment page.

Step 3
Remove and reinsert the cartridge, this time with no tape on any of the contacts. Check to see if the printer recognizes the cartridge as being full.

Step 4
Repeat the above steps if the cartridge is still shown as being empty. This time, use the bottom corner contact squares instead of the top ones. If you are still unable to reset the cartridges, using multiple cartridges is likely the only way to do it.

Make sure the surface you use is safe to possibly spill on. Cover it with paper towels or old rags that you don't mind getting toner on.

Step 4
Insert the correct color ink into the cartridge with the syringe. If you're refilling black ink, use about 20 milliliters. For color ink, use 10 milliliters per chamber.

Step 5
Reseal the filling hole if it is on the cartridge bottom. Make sure it's airtight. Squeeze the cartridge sides and insert the plug that should have come with the refill kit. A small amount of ink should drip from the print head.

Let the cartridge stand with the print head down for a couple of minutes before putting it back in the printer. This will draw out excessive ink and equalize pressure in the cartridge.
