SC 302 error on Ricoh copiers

  • Description:High Voltage Power Source: Charge: Output Error The machine detects the error detection signal “L (unexpected)” 10 times for 200 msec consecutively when monitoring the error signal every 20 msec during outputting the PWM signal.
  • Causes:Hardware error • Input / Output connector is disconnected. • Input / Output harness is short-circuited. • Surface/air clearance insufficient (arc discharge) • BCU error (signal error) • HVPS defective Load error • Grounding fault of charging output, short-circuit with other outputs • Surface/air clearance insufficient in charging output path (including distance from other outputs) • Unexpected deterioration of drum and over current due to pinholes gap error between the drum and charge roller (PCU error). • Over current due to drum surface condensation • PCU is disconnected.

Method 1: Fix SC 302 error on Ricoh copiers

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.

step 1: Please enter the code to clear the error first to see if it is gone
You press the Yellow button ( Clear mode ) + 107 + Red (stop clear) hold until the SP Mode panel appears , remove your hands

Next, press on the numeric keypad ” 5810″ and then press the ” #” key on the keyboard.
Then click ” Execer”.
And proceed to shutdown about 10 seconds. Then turn ON the device and see if the device has reported any errors?
Do not worry if your device returns an empty error without showing anything, skip to step 4, perform step 5.
Step 2 : If step 1 is completed without error, continue to Step 2:
You need to remove the drum assembly from the machine and proceed to remove and clean the rubber roller (charge roller). If not, you can try another charger shaft.
If step 1 does not work, then try to check again.
If step 2  still does not work, then check the high pressure board after the device.
Good luck.
