To reset the HP C6657A (#57) or HP C8728A (#28)

To reset the HP C6657A (#57) or HP C8728A (#28):
1. Refill your cartridge using your Mr. Ink Jet refill kit.

2. Following the diagram at right, place a piece of adhesive tape covering the only the blue colored contact (a contact is the individual copper square). Make sure that only that contact is covered and no others. *Please note that the contacts shown are colored for illustrative purposes only. You will not have blue or red contacts on your cartridge.

3. Place cartridge in the printer. The printer may tell you that there is a problem with your cartridge. Ignore this message. The printer may print an alignment page. If so, allow it to do so.

4. Take the cartridge out of the printer. Leave the tape from blue contact. Place another piece of tape over the red colored contact. Make sure that only that contact is covered and no others. *Please note that the contacts shown are colored for illustrative purposes only. You will not have blue or red contacts on your cartridge.

5. Follow step 3 again.

6. Take the cartridge out of the printer for the final time. Take the remaining tape off and place back in the printer. The printer should print out an alignment page and the estimated ink level in the toolbox should read full.

Reset Method 2:

If Reset Method 1 did not work on your printer, you can cycle cartridges through to reset the level. You will need two extra cartridges and the one you refilled. First, put the refilled cartridge in the printer. Allow it to recognize the cartridge and print an alignment page. Take that cartridge out and place in the first extra cartridge. Allow it to recognize and print an alignment page. Take the first extra cartridge out and place the second extra cartridge in. Allow it to recognize and print an alignment page. Take the second extra cartridge out. Place the refilled cartridge back in the printer. It will print an alignment page and then the estimated ink level will be reset to full.
