Message d'erreur sur la Kyocera

Make sure document feeder cable screws are tight and if cable guard (metal bracket) is not installed make sure it is not too close to the wall.

ERROR 0410, COMMUNICATION ERROR, DF/COPIER. DF WILL LIKELY RUN FINE BY ITSELF IN SERVICE MODE BUT NOT TALKING TO COPIER. INTERMITTENT STRANGE PROBLEM. THERE ARE SOME SPECIFIC RELATED SYMPTOMS SOMETIMES.
WHAT DOESN'T WORK, TRIED COPIER ENGINE BOARD, DF MAIN BOARD, HARNESS, KYOCERA GROUNDING KIT + TECH SUPPORT. ALL BAFFLED.
WHAT DID WORK, FINALLY. I'VE FIXED 3 SO FAR. COMMUNICATION TIMING IS BASED ON PAPER SENSORS & MOTOR PULSES IN DF. PROBLEM LOST PULSES. EITHER ELECTRICAL NOISE FROM MOTORS OR BAD ENCODER(S) (IN MOTORS) OR BAD ONE WAY CLUTCH(ES) (IN GEARS) OR BAD SENSOR(S). I REPLACED ALL. 2 OF EACH ARE NEEDED.
I AM A KYOCERA CERTIFIED COPIER/PRINTER TECH WITH 20 YEARS EXPERIENCE. I'VE NOTIFIED A REGIONAL MANAGER AT KYOCERA OF THIS GROWING ISSUE AND THE SOLUTION.
