That is a charge roller current leak. A current leak signal for
the charge roller is detected. Possible cause- charge roller damaged or high voltage supply board defective. Check the charge roller first. On the drum, the rubbery roller.

Funtional problem SC302

It depends on which Ricoh model.
Some Ricoh copier/printer use a corona wire for charging the drum, so SC302 means that the corona wire is ether broken or have some current leak. but in most case the wire is broken.
Other Ricoh copier/printer use a charge roller for drum charge, so on this model SC302 usually appear when the charge roller have a bad contact.

How can i solve error code sc:302 in ricoh Aficio 2000 copier.

You should have a service technician take a look at your copier. SC302 is a charge roller current error, and it could be caused by a number of things, from a dirty charge roller to a faulty high voltage supply board.

In the meantime, try turning the machine off, unplugging it, and then plugging it back in and turning it on the see if the error message will clear.

I have a gestetner DSm745e it keeps on poping out a code SC302 however i don't have a manual for it can you help me?

Charge roller current leak.The polling module detects a current leak of the charge roller.Check,clean or change the charge roller,verify the connection of the PCU,and verify the high voltage suplly board conectors.Turning the main power switch OFF and ON resets the SC code if the error is caused by incorrect sensor detection.

Error code SC302

From the Ricoh-Lanier Error Code Sheet:
SC302: Charge Corona Output Error 3 - Grid Voltage error - Charger Roller Current Leak.

I would suggest replacing first the charge roller and if that doesnt fix it, the HIgh Voltage Supply Board.

Error sc 302

From the Ricoh-Lanier Error Code Sheet:
SC302: Charge Corona Output Error 3 - Grid Voltage error - Charger Roller Current Leak.

In English:
I would check the roller motor for a short, frayed, or damaged wires. Use a voltometer and compare the voltage to the cleaner motor.
