2. Following the diagram at right, place a piece of adhesive tape covering the HP 45 printhead, contacts, resetting the 51645aonly the four blue colored contacts (a contact is the individual copper square). Make sure that only those four are covered and no others.
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. Remove the tape from the four blue contacts. Place the tape over the four red colored contacts. Make sure that only those four are covered and no others.
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.
If Reset Method 1 did not work on your printer, go through the same procedure again, but this time using the green colored contacts in step 2 and the brown colored contacts in step 4. This method is more commonly used for the #15 or in the later officejet printers.
