Service call-sc491 ricoh printer problem

This is most likely a fuser issue. If you have a spare laying around, I would suggest replacing your fuser. If you have a contract with Ricoh, I would suggest placing a service call for them to come out and look at the machine.

Unknown if this is the same model printer or not, as you question doesn't say.

Printer Ricoh sp 210SU service call error SC491 using compatable cartridge...

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.

Most likely a bad PCU (drum unit) causing the issue/error code but hard to reply in more detail if you don't provide the model number of you Ricoh/Savin/Gestetner/Lanier copier.

MPC 2500 SC442 what is the problem?

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.
