@PROKASH, Welcome to the HP Support Community!
Thanks for reaching out about your query regarding printhead error signal!
We're thrilled to have the opportunity to assist you and provide a solution.
The printhead error signal on your HP printer signifies that there might be an issue with one or both of the printheads. Here is a guide to help troubleshoot and resolve the issue:
Printhead is Missing:
- Solution: Ensure that both printheads are properly installed in the printer. If a printhead is missing, install the missing printhead.
Printhead Installation:
- Solution: Make sure the printheads are installed correctly. Open the printhead access door and check that the printheads are securely inserted in their correct slots.
Residual Packaging:
- Solution: Verify that there are no orange plugs or plastic tapes on any of the printheads. If there is any, remove it carefully and then reinsert the printhead.
Incorrect or Damaged Printhead:
- Solution: Check that you are using the correct HP printheads for your printer model. If the printheads are incompatible or damaged, you may need to replace them with new ones.
Printhead Alignment:
- Solution: Perform a printhead alignment. You can do this by printing an alignment page and following the instructions provided by your printer. Typically, this involves placing the printed page on the scanner glass and pressing a copy button to scan the page for alignment.
Printhead Latch:
- Solution: Ensure that the printhead latch is properly closed. Do not open the printhead latch unless instructed to do so.
Hope this helps!
Take care, and have an amazing day!
