- If a postage-paid mailing label and a return envelope were included with the new printhead, HP would like to have the old part back for analysis. Please follow the instructions in Step four at the end of this document to return the printhead.
- If no post-paid mailing label came with the new printhead, you can recycle the old part. Put the printhead (with the cartridges still inserted) into a plastic bag, then go to hp.com/recycle for information on recycling the old printhead and cartridges.
Step two: Insert the new printhead
