E56-1 COMMUNICATION SYSTEM CONTROL MAIN BODY CONTROL PROBLEM. I REPLACED THE SOLENOID AND GEAR FOR CASSETTE 1 AND DIDN'T TOUCH ANYTHING ELSE. CAN I RESET THIS CODE. THANKS T

its a communication error between the system board and the main board. you can try and flash new firmware for both. if that doesn't work,replace both boards and flash firmware. nothing to do with paper trays........
