goodluck

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.

546 A Unstable fusing temperature The fusing temperature varies 50°C or more within 1 second twice continuously. • Thermistor defective(temp. senzors in the fixing unit) • Poor connection of the fusing unit • Power supply unit defective

you have an over heat error. you need to test your thermistors, s and lamps for continuity.replace bad parts. then you need to go to service mode and reset the code

Fusing unit trouble.Clean the thermofuse and thermistors,check the heater lamp.After ,enter in the service mode turn the power switch OFF unplugged the crd.Wait 10 sec. plugg the cords and turn ON the machine.I think the Savin is based the Ricoh copiers machine.The service enter code is : Press the toral clear key - 1 - 0 - 7 -hold down the C key more 3 sec.

Parts availability ended for this machine Jan of 07, now is a good time just to chuck it.

Hit the yellow botton ( Reset/ CA), then 1 then 0 then7 , then hold down the (Stop) botton till the display changes... Then turn the copier "OFF" then "ON" it may clear the code. The code has to do with your fixing unit.

SC 553 is a fuser overheat error. If you have a fuser great, but you will still have to reset the code. Clear modes, 1, 0 ,7, press and hold clear/stop key. Menu will change, select copy sp. From there, select 5, (mode), scroll till you get to 5810. Select it, and press execute, then exit back to copy sp. Select 7 (data log) then scroll until you get to 7807. Select it, and press execute. Exit all of the way out, and recycle the power.

If it comes to ready, great. Try it. If it codes out again, you have a problem, possibly thermisters, (in the fuser), power supply getting stuck on, I/O board not regulating the power supply. Could be any of these things.

But start by resetting the code. Could be a a thermister got some toner stuck under it, and the other thermister detected a difference. It really could be that easy.
