Hi @Grahame4,

Welcome to the HP Support Community! 

Thanks for reaching out about your query regarding your printer!

We're thrilled to have the opportunity to assist you and provide a solution.

Try these steps:

Perform a Hard Reset:

• Disconnect the printer's power cable while it is still turned on.
• Unplug the power adapter from the wall outlet.
• Wait for about 60 seconds to let the residual charge dissipate from the printer.
• Reconnect the power cable to the printer and wall outlet.
• Power on your printer to check if the error persists.

Check for Paper Jams or Blockages:

• Open the printer's access doors and check for any paper jams or obstructions inside the printer.
• Remove any paper fragments and ensure the print carriage can move freely.

Update Printer Firmware:

• If possible, ensure your printer's firmware is up to date. This can often fix known bugs and issues.
• Visit the HP Support website and download the latest firmware for your printer model.

Reset the Printer to Factory Settings:

• If the error persists, you might consider resetting the printer to its factory settings. Note that this will erase any custom settings or configurations.
• Navigate to the printer's menu and look for the option to reset to factory settings. If this option isn’t visible, refer to the user manual for more instructions.

I hope this helps.
