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.

Your computer is not connected to your home network, your printer is not connected to your home network. That is the way they communicate.

SC553 means an overheat error on the pressure roller, but this RTB corrects this to an overheat error on the heating roller. As a solution the heating roller thermistor should be replaced or the connections of this thermistor are faulty.
