SC541 is a fuser heat failure. This means the fuser, which heats up and fuses the toner onto the paper, is not heating properly. Most of the time on Ricoh's this is caused by failure of the thermistor(s) which are responsible for reading the temperature of the fuser unit.
I would look in your local phonebook's yellow pages under copier service/supplies. Either find an independent servicer, such as someone listed as "services all makes and models" or look for a Ricoh, Gestetner or Savin dealer. The Gestetner and Savin makes are exactly the same as Ricoh so they may be able to help.
Good Luck and Thank You for using Fixya.

• Someone forgot to remove the toner
seal of the PCU

Clean connector of TD sensor and
Try Change the development unit, adjust TD sensor.
Clean and you verify the connector of PCU.
