Ricoh 430dn error sc565

SOURCE: cause for error code sc560 on ricoh ap3850c

H there below is what is stated in the service manual and I suggest to change the power cord before the main PSU (Power Supply Unit)


SC 560 Zero Cross Error

When the power switch is turned on. The machine checks how many Zero-cross signals are generated during 500 ms. If the number of Zero-cross signals is more than 66 or less than 45 and the condition is detected more than 10 times this code is shown.

Cause is electrical noise in the supply from the power cord.
Solution

• Change to another power wall socket
• Change power cord
• Replace main PSU (Power Supply Unit)

SOURCE: Ricoh fuser oil replace message

That is not a good idea. The oil is kept track of by counting pages, not by a sensor that measures the oil level. The oil runs out and the machine can't tell and now you have ruined the fuser. Which cost a lot more than the oil tank.
