I have HP Office Jet Pro 7740.  Bought it new many years ago & it's been a great printer.  It is now showing error code B80CD5A4.  What does that mean & how to fix it?

Hi @billjones9,

Welcome to the HP Support Community.
 

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

The error code B80CD5A4 on your HP OfficeJet Pro 7740 Wide Format All-in-One Printer is a critical system error that typically indicates a firmware or hardware fault often related to the printhead, ink system, or internal electronics.
 

Here’s how to troubleshoot the issue:

1. Perform a Full Power Reset

• Turn off the printer.
• Unplug the power cord from both the printer and the wall outlet.
• Wait at least 60 seconds.
• Plug the power cord directly into a wall outlet (avoid surge protectors).
• Turn the printer back on.

2. Use HP Smart’s Diagnose & Fix Tool

HP recommends using the Diagnose & Fix feature in the HP Smart app for Windows:

• Download or open the HP Smart app:
  👉 HP Smart - Free download and install on Windows | Microsoft Store
• Go to Printer Settings > Diagnose & Fix.
• Follow the prompts to scan and repair issues like firmware faults, spooler errors, or offline status

3. Update Firmware

Outdated firmware can trigger system errors:

• On the printer’s touchscreen, go to Setup > Printer Maintenance > Update Printer.
• Or use HP Smart to check for updates.

4. Check for Ink System Issues

• Remove all cartridges and inspect for leaks or damage.
• Reinsert cartridges firmly.
• If you have a spare set of genuine HP cartridges, try swapping them in.

I hope this helps.

Take care, and have an amazing day!
