@Bryn3 Due to the current global COVID-19 situation, we're seeing an influx of customers coming in for support and we appreciate your patience.
That said, here are a few steps to help resolve the issue:
Step 1: Check the error
In addition to the alphanumeric code, look for an error message that describes the problem.
Not all alphanumeric codes begin with 0x; some begin with B or C.
If the message contains a description and an alphanumeric error code, the steps in this document do not apply. Search HP Customer Support for a troubleshooting document that matches the description you see.
Example of an error message with additional text that describes the problem
If the message contains only the error code, continue to the next step.

Step 2: Reset the printer
Reset the printer to recover from printer failures.
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.
HP recommends plugging the printer directly into a wall outlet.
If the error message persists, continue to the next step.
