Hello,
50.x errors are often a problem related to the fuser.
In order to mitigate this incident, please redesign the power supply to the printer:
- With the printer turned on, disconnect the power cord from the printer.
- Unplug the power cord from the power source.
- Wait 60 seconds.
- Reconnect the power cord to a wall outlet and to the printer.
NOTE:
HP recommends plugging the printer directly into a wall outlet. - Turn the printer on.
If the problem persists, follow the next steps:
- With the printer turned on, disconnect the power cord from the printer.
- Unplug the power cord from the power source.
- Wait 25 minutes.
- Reconnect the power cord to a wall outlet and to the printer.
NOTE:
HP recommends plugging the printer directly into a wall outlet. - Turn the printer on.
Do not hesitate to solicit us if you need.

This is a fuser drive error. Below are customer steps to try in resolving the error.
- Turn off the power by using the power switch, and then wait at least 30 seconds.
- Turn on the power and wait for the product to initialize
- If the error returns, turn the printer off, unplug the device from any power-strips or uninterrupted power supplies, and plug printer directly in to a wall socket.
- Ensure that the power source meets the printer requirements. Ensure that the printer is the only device using the circuit.
- Ensure the paper type and fuser mode are correct for paper being used.
- If the error persists, please contact customer support at: www.hp.com/go/contactHP.
