Hi
I found this explanation of your error, although my understanding of it is not entirely clear. Code: C6400 Description: Zero-cross signal error
Interrupt of the zero-cross signal does not occur more than 1 s. Causes: Poor contact in the connector terminals.
Defective power source PWB.
Defective engine PWB
You can find this here: Error Codes Kyocera Mita TASKalfa 221 Code C6400
and also by changing the drop down menus along the top of the page you can view other errors for your machine and for other models and makes. You can also use the link to get a Service Manual for your machine.
Hope this is helpful, if so would you please register that with Fixya
Cheers
Contents: Zero-crossing signal problem • The engine PWB does not detect the zero-crossing signal for the time specified below. At power-on: 3 s Others: 5 s
Causes: Poor contact in the connector terminals. Check procedures/corrective measures: Check the connection of connectors YC7 on the engine PWB and YC2 on the power supply PWB, and the continuity across the connector terminals. Repair or replace if necessary.
Causes: Defective power supply PWB. Check procedures/corrective measures: Check if the zero-crossing signal is output from YC2-11 on the power supply PWB. If not, replace the power supply PWB.
Causes: Defective engine PWB. Check procedures/corrective measures: Replace the engine PWB if C6400 is detected while YC2-11 on the power supply PWB outputs the zero-crossing signal.
Hello, the c6000 is the Fuser heater 1/2 defective --- but is you are getting the c6400 --- is a zero cross signal error which means defective PWB. You must replace the engine PWB or the power source PWB and check for correct operations.
The cheapest route would be to replace the fuser but with the c6400 code I believe you would just be throwing your money away.
