HP error 50 Fuser error
The fuser (the hot part that melts toner onto the paper) is not heating correctly.
How to fix it
- Turn the printer off and leave it for 20 minutes to cool.
- Plug it straight into a wall socket, not a UPS or power strip. Fusers draw a lot of power.
- If the fuser is removable, reseat it.
- Turn the printer back on.
Is it worth fixing?
If it persists, the fuser needs replacing. On business LaserJets that is a standard part and worth doing.
