SC491 on a Ricoh SP 210SU is a code for bias leak.

The machine detects that a bias leak has occured from the drum charge, development charge or transfer charge.
PWM signals are sampled at 20 msec. intervals. This SC is issued if 10 PWM samplings within 200 msec. are abnormal.

• HVPS (high voltage power supply) harness loose, broken, defective
• HVPS board defective
• AIO terminal defective (the terminal for the toner cartridge)
• Cycle the machine off/on
• Check all the harness connections of the HVPS
• Check spring-loaded AIO terminal installation behind the HVPS.
• Replace HVPS.

Usually this error is related to the cartridge. Some manufacturers of compatible cartridges will replace the cartridge with a new one.
At least they should give a discount based on how many pages that was printed before it failed.

I have not seen this problem with a new genuine Ricoh cartridge.
It is important that the cartridge is not refilled more then 3 times. There is no counter on this, and companies that refill cartridges they collect (with unknown number of cartridges) may have problems quite often.

Wat i can do with my printer ricoh aficio sp c420 dn


Good afternoon Omar, my name is steve.

This error code can relate to one or two things.

1. PCU Photo-Conductive Unit is bad or needs to be replaced.

2. A defective High Voltage power supply board.

If it has not been serviced in awhile,and no user supplies other than toner has been installed in it, I would consider the first option.

I hope this assists you, best regards,Steve

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.

sc491 is a high voltage output error. Combined with your jamming issue, it sounds like a possible electrical problem somewhere. A good first step is to turn the machine off and unplug it, then take off the covers and reset any connections or cables you can get to.

If the problem persists, you should have a service technician take a look at it because it might need a board replaced.
