note:

When you install a new printhead, HP recommends that you use new cartridges. You can reuse your existing cartridges, but if they are low on ink, the calibration of the new printhead could result in a low ink condition. It is best to have new cartridges on hand when replacing the printhead.

note:

HP does not always ask that customers return all failed parts, so you might not have a prepaid mailing label and return instructions. You can ignore these steps if you did not receive the return documents.

1. Put the old printhead assembly into the package that the new part came in.

2. Peel off the lid sticker labeled ‘B’ and use it to seal the printhead assembly package.

3. Use the orange caps from the new cartridges to cap the old cartridges.

4. Put the old parts and the form that came with the new parts into the box the new parts came in. If possible, also include a print sample showing the issue with the old printhead.

5. Close the box, apply the prepaid mailing label, and then put the package in the mail.
