Ricoh SC543 Fusing Overheat Error
What it means
The fusing unit read a temperature above its safe range, so the machine stopped itself. This is a protective stop rather than damage in itself. Because it involves a heating element, a code that repeats after a reset is one to hand to a technician rather than keep clearing.
A full step-by-step guide is on the way
We publish guides only after checking each step against the manufacturer's own documentation, so this one is still being written. In the meantime, if the code relates to a jam or an obstruction, switching the printer off, unplugging it for a minute, and checking for anything stuck resolves a large share of cases. For a hardware fault, contact the manufacturer.
