How many pages has this one printed?

Is this the only one you have access to? You could try swapping the fuser.

When the plastic gears start turning without grease the printer will growl. If you can clean and lube them that sometimes gets rid of the noise. Need special grease for plastic gears. If you think this is the problem I will send you the link for the grease.

When the page comes out white the usual problem is the safety cover on the laser scanner assembly. When you insert the toner cartridge it moves a lever that opens the safety cover. If the laser or mirror motor was bad you would get an error code.

Sometimes a toner cartridge can make strange noises. Can you try another cartridge, even an empty one, to see if that is the source of the noise?

Yes, try another toner as it could be the source of your noise & print defect.

1. I find another same model of 4350 and i try to shif the parts on the faulty printer to the working printer and i found after i replace the main board and the printer work.print out text image.:confused::confused::confused:.
2.why i replace the swing plate assy will cause this problem???

i need to remove the main board than can replace the hold swing plate assy.
Then put back the main board and test print not text image.

Now the print work with the good printer main board and all the parts like scanner,toner formatter board,control board(at the side of the printer)all work on another printer.only the main board not.????
