The Hewlett-Packard OfficeJet 5510 uses the #56 (C6656A) black ink cartridge and the #57 (C6657A) colour ink cartridge. When overriding the ink level gauge on the HP 5510 printer, it's important to follow the instructions specifically catered to resetting these two models of ink cartridges because the instructions will vary between other models. Having the ability to override the ink level gauge is helpful when refilling ink cartridges and also when it's past the cartridges two-year expiration date.
Hold the cartridge with the copper contacts facing you, but do not touch the copper contacts. You will see six columns of copper contacts. Place a piece of adhesive tape over the top copper contact in the second column. Make sure that only that contact is covered.
Place the cartridge in the printer. Ignore the message that there is a problem with your cartridge and allow the printer to print an alignment page.
Remove the cartridge from the printer and hold it with the copper contacts facing you. Leave the first piece of adhesive tape over the contact.
Place a piece of adhesive tape over the top copper contact in the sixth column. There should now be two contacts covered.
Place the cartridge in the printer a second time. Just as the last time, ignore the message that there is a problem with your cartridge and allow the printer to print an alignment page.
Remove the cartridge from the printer and remove both pieces of adhesive tape.
Place the cartridge back into the printer. The printer should now recognise the cartridge as new and print an alignment page.
When placing the cartridge in your printer with the adhesive tape, be sure to make the tape stick well so it doesn't fall off and cause damage to the printer.
