HP uses a linear supply on the LJ line—it's not an SMPS that can handle 100-240V global voltage. Were you trying to use a 120V printer on a 240V outlet? That's usually what causes this. Running 120V on a 240V power supply would create a brownout condition which CAN cause damage, but not in every instance.

The only way to use the 120V LJ printers on 240V is to swap the 120V fuser for a 240V one and the 120V power supply. If the printer has any secondary driver boards, like an LVPS, those may need to be swapped—but it's usually not needed—it's the main power supply (sometimes called LVPS) and fuser that needs to be swapped out.

If the printer has any secondary driver boards like a LVPS, those may need to be swapped -- but usually not given they tend to be built to run on 120/240V setups to remove one less unique component.
