If a postage-paid mailing label and a return envelope are included with the new printhead, HP would like to have the old part back for analysis. Follow the instructions in the step to return the failed parts to HP at the end of this document.
-
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 2: Insert the new printhead
Follow these steps to insert the new printhead into the printer.

Step 3: Insert the new cartridges
Follow these steps to insert the new cartridges.
Important: To avoid startup failures, HP recommends that you use the new cartridges that came with the new printhead.
-
Remove the new cartridge from the package.
-
Slide the new cartridge into its slot, and then gently push it forward until it clicks into place.
note:
Make sure that the colored dot on the cartridge label matches the colored dot on the slot.

caution:
Do not lift the latch handle on the carriage to insert cartridges. This might cause the printhead or cartridges to be incorrectlyseated, which could damage the print mechanism and cause printing problems.
-
Repeat these steps to insert other cartridges.
-
Close the cartridge access door.
The HP printer starts an initialization process, which takes about six minutes. It is normal for the printer to make noises during this process. After the process completes, the printer prints an alignment page.
Step 4: Return failed parts to HP
Return the failed parts if the new printhead assembly came with a post-paid mailing label and instructions to return the failed parts to HP. HP would like to analyze the parts in order to improve its printers in the future.
note:
Not all customers are requested to return the old parts. If the replacement printhead assembly came without a post-paid return mailing label, ignore the rest of this section.

Place the ink absorbing pad into the plastic package that came with the new printhead.
