SC547 - Zero cross signal malfunction
Zero cross signals are not detected within a certain period within 500 ms after the main power switch has been turned on.
- Possible causes -
· Power supply board defective
· Noise on the ac power line
Open door
Check the fuse FU1 y FU2 in the power supply board FU1 display open door Without saying as. But it would have to review all the fuses.

Comments:
- The flat cable of the laser also can cause the fault of open door, cut or badly connected this also it can be indicate door opened without indicating as. But all the problem seems to come from the power supply...
Good luck...

    El
    cable plano del laser cortado o mal conectado, tambien puede provocar
    la falla de puerta abierta sin indicar cual de ellas está abierta.

Well, you sound like you figured out part of your problem. If the open door symbol is showing, then you need to find out which door the machine thinks its still open.
Check all the doors, front, both right and left doors, and if the machine has a bottom console, then check those doors also.
I would open every door and reclose them again and see if you can get the DOOR OPEN symbol to go away. Need to start with the basic first.
Once this is cleared then we can see if we can troubleshoot any other problems.
(Most doors have a little stub that sticks out that either goes in between a sensor, or pushes on a switch to tell the machine that the door is closed.
If after opening and closing each door, and the machine still says Door open, then Next step I would take is to see if there are any places on the door that looks like a small piece of plastic might have broken off.
Let me know what you find.
Good luck.

Code SC 547 00


SC 547 is a fuser problem. Press clear modes, 1, 0, 7, and press and hold clear/stop/ Enter copy sp. Select 5 for mode. exit all of the way out, and recycle the power. If something in the fuser is bad, it will do it again. If it comes to ready, then the thermister is probably dirty. As for the door, make sure all are closed tight, including the lower right door.
