SC 571 error

IH inverter current error at power on. Either the fuser is damaged or the invertor coil is defective. You really should have a Ricoh tech look at that one. It is not an easy fix for the layman.

Ink head temperature sensor. replace the sensor

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.

You have a Fuser Temperature warm-up error, Hot roller warm-up error.
Verify the heater lamps, thermistor and thermofuse continuity.
Enter in the SP mode, turn OFF the main switch, unplug the machine, wait 10 seconds,
plug in and turn ON the copier.
If you need to reset the fuser, Enter SP 5-810 (SC code reset) and
select "1". Then simultaneously press the Original Type key and the OK (or
R/#) key. (There is no need to turn the main switch off and on.).

This is a fuser error code resetable by entering service mode. -Carl

Fuser warm up error. Code can only be reset in service mode after the problem is fixed

there is too much oil in the fuser tank(there should be little oil)

SC 571
• Defective oil end sensor
• Defective oil overflow sensor
• Defective sensor cable
• Oil supply unit not installed

you need to enter the service mode to clear the error(service tech only)

SC 571 is a fusing error caused by not being seated properly or the oil sensor is coated with oil.

More than likely when the machine was move oil coated the senor in the fuser and it has to be taken apart to be cleaned.

Take the fuser out and clean under the thermistors, and reset the code by entering test mode ( turn off printer hold down online and escape as you turn on printer selece 2 engine go to sp5-810 and reset this.
-Carl, please let me know if this helps.

Yes this is a Polygon Mirror motor error it is reasonably common in the Lanier digitals. The mirror motor can be ordered separtetly to the laser unit.
