red light flashing will not print saying blocked

Hi @debgran,

Welcome to the HP Support Community.
 

Thank you for posting your query. I will be glad to help you.

A red light flashing on your HP printer with a “blocked” message usually means the printer has detected an issue that prevents printing. Here are the troubleshooting steps:

Common Causes

• Paper jam or misfeed.
• Cartridge error (missing, incompatible, or not seated properly).
• Door or cover open.
• The printhead carriage is stuck.
• Foreign object inside the printer.

Steps to Fix It

1. Check for Paper Jams

• Turn off the printer.
• Open all access doors (input tray, output tray, rear access if available).
• Remove any jammed paper or debris.
• Make sure rollers are clean and move freely.

2. Inspect Cartridges

• Open the cartridge access door.
• Remove and reseat cartridges firmly.
• Ensure they are genuine HP cartridges.
• If the error persists, clean the cartridge contacts with a lint-free cloth slightly dampened with distilled water.

3. Check Printhead Carriage

• Power on the printer.
• Open the cartridge door and see if the carriage moves.
• If stuck, gently move it to the center and clear any obstruction.

4. Close All Doors Securely

• Make sure the cartridge access door and paper tray are fully closed.

5. Restart the Printer

• Disconnect the power cord for 60 seconds.
• Plug it back in and turn on the printer.

I hope this helps.

Take care and have an amazing day!
