Does anyone have a clue what this code means and how I can fix it. I have an older machine with no maintenance contract and would like to fix it myself it is simple enough. Thanks.

Ricoh Aficio SP 4210N- Code SC 543

This is a common error code for Ricoh copiers, Savin and Gestetner copiers that need service. Recently Ricoh has purchased Lanier and now is naming all their new machines Lanier instead of Gestetner, Savin and Ricoh. However, the copier service error codes have remained he same.
When you get this copier printer service code it means the fuser or fixing assembly (same part) has thermistor problem. The copier fuser's thermistors help regulate the temperature of the fuser assembly. The fuser assembly on all copiers including Canon, Kyocera, Ricoh, Sharp and other brands is the part that melts the toner onto the page.
Getting back to the repairing the copier on Ricoh, Savin, Lanier and Gestetner models that have the fuser or fixing code error. The majority of the time the fusers' thermistors (Middle and read) need to be replaced. Just cleaning them will not solve the copier repair service code.
It is usually, depending upon the machine, its a 1 to 2 hour copier repair job because the copier repair service technician will need to dissemble the fuser, insert the two new thermistors, re-assemble, reset the error code and test the copier machine repair. Also, ask the copier technicians to to do a copier cleaning maintenance while on site.

Error code SC542 on a Ricoh 3245

Hello, this code is : Fusing temp. warming-up error. This means that the fuser did not warm-up in the allowed time. Possible causing-- in order; Thermistor bad or out of position,
fuser lamp bad,
thermofuse bad,
BICU board defective,
power supply board bad,
poor fusing unit connection ----check this first if you had the fuser out of the machine.

If you would like to talk, I can see if we can try to reset the code -- sometimes if the machine is to cold at warm-up the code will throw. # 216-701-1591. Thank you.

A sc541 code is with the fixing ass'y did you try to reset it? Did it come right back? Is the fuser warm to the touch? If so it is most likly to be one or both of the termister in the fuser. If it is cold it may be the fuser heatting lamp or thermal fuse
