Question about Ricoh FAX3800L Plain Paper Laser
Machine is sending but not producing transmission report and display is showing error 3-31H. What do I do?
This is a failure of the polygonal mirror motor. To check, Test point CN14-4 on the FDU board. If it does not go to low within 10sec of the motor being turned on. Motor has failed. Also check test point CN 14-1 that +24v is supplied to the motor.
This is a common problem, it is simple to change. However, the machine must be reset after each test.
