Ricoh SC542 Fusing Temperature Error
What it means
The fusing unit did not reach its working temperature within the time the machine allows. On many Ricoh models the code can be cleared from the service menu, and it stays away if the cause was a cold start or a brief power problem. A code that keeps coming back points at the fuser or its thermistor.

Is the SC542 error serious?
This one usually points at a hardware fault rather than something a setting will clear, so treat an unchanged result after a power cycle as a reason to contact the manufacturer rather than to keep trying.
Different code or problem?
Switch off and unplug a printer before reaching inside it. If a fault involves the power supply or internal electronics, or the machine is under warranty, contact the manufacturer or a qualified technician. Full disclaimer.
