🛠️ How to Fix Each HP Printer Error Code
⚠️ 1. HP Error Code 0.x – Internal Hardware or Firmware Error
Cause:
This code usually indicates a problem with firmware, memory, or internal hardware.
How to Fix It:
- Power cycle the printer: Turn it off, unplug it, wait 60 seconds, then power it back on.
- Update firmware: Go to HP's support site and check for the latest firmware update.
- Remove external accessories: Disconnect extra RAM or USB devices to rule out conflicts.
- Reset printer to factory settings (only if the issue persists and you’ve backed up settings).
♨️ 2. HP Error Code 50.x – Fuser Error
Cause:
The fuser (the part that applies heat to bond toner to paper) isn’t heating correctly.
How to Fix It:
- Restart the printer: Turn it off, unplug it for 30 seconds, then restart.
- Check the power source: Make sure the printer is plugged directly into a wall outlet (not a surge protector).
- Let the printer cool down: If used heavily, allow it to rest for 10–15 minutes.
- Replace the fuser unit: If the error persists, the fuser may be damaged and need replacement.
🔧 Tip: The “x” in 50.x refers to a specific fuser issue (e.g., 50.2 = warm-up failure).

Cause:
This is often caused by a corrupted print job, outdated firmware, or network conflicts.

- Update printer firmware from HP’s support page.
- Disable third-party apps installed on the printer, if any.
