View Full Version : kyocera KM5530 Dead
got a problem with a Kyocera KM5530
its died once before and i had to replace tha power supply and it worked and now its blown another power supply!?!? within a week or 2... now the power is fine its very reliable wall supply so its something machine related.
anyone got any ideas? :8o:
how do you know for a fact that the wall supply is good 100% of time unless you stayed and watched a good meter for 1 to 2 weeks? if you have access to a ups/line conditioner, i would hook that up and see if it helps. at least a very good quality surge protector. i also would ask cust. what they were doing on machine each time pwr. supply blew. wish i could give better info but i'm not very familiar with the 5530. good luck!
cmon guys i need more help haha
thanx but i think the problem comes from the machine internbally like something making it go pop im not sure...
HAD A PINCHED WIRE FOR THE LCD DISPLAY POP A POWER SUPPLY PCB ON ME BEFORE ON A 5530. CUSTOMER NOTICED THE LCD FLICKER ON/OFF JUST FOR A QUICK SEC AND FIRST THING I THOUGHT TO DO IS TAKE THE OP. PANEL APART BEFORE I PUT THE NEW PS PCB IN. KEEP AN EYE OUT FOR THINGS THAT JUST AINT RIGHT.

Does the machine have a fax kit? If it does remove the power supply for that and see if the machine power comes back.

Switch off the machine. Disconect it from the wall plug then open the back cover.
diconect and reconect all the visible conectors especially
ones feeding the duplex,scanner board,and all the conectors around the power suply,and the raser unit.
plug the machine back to the wall plug.Switch the machine
on and see if it comes alive.Try that.

put good surge supressor on it. try a panamax brand.
put a recording meter on the wall outlet, like a fluke 85.
check the wires leading to the rear fuser lamps.

Normally the only thing that will continually pop the power source pcb is ac shorted to ground. Check your fuser.

I've had the photo sensors behind drawer #3 get knock off their mounts and the drawer chews up the wiring. On my machine this took out the engine pcb, but maybe on yours....? One of my techs found on another machine the the big honking capacitor on the power supply had cracked solder which caused a dead machine symptom.
KM power supplies have an interupt built in that requires you to disconnect the plug from the wall, go have a cigarette, then come back and plug it in. The reset process won't start until you actually unplug it. This was first seen on the 6060's but now is a standard feature. The obvious question is "what is kicking it offline?", but the power supply pcb should still be good.
