Ricoh 3245c code is SC542

A SC542 error is a fuser problem. Did you have a power problem? You can try to reset it by turning the copier "ON" and once you have the code displayed on the screen.... Press the Yellow clear botton once - then the #'s 1 - 0 - 7, one at a time then press the Red Stop botton till the display changes..... Once, it changes turn the Main Power Off, not the one on the control pannel. Then turn it back "ON" and that should take care of it for you.... If it did not, you may have some more problems that can not be reset till they are repaired.. Good Luck
