Need help hallo gays am having trouble with a xerox 5825 which is showimg me error J3 and i really don't know how to fix it right,

you don't really need to know that. just go ahead and buy a new one.stop being so gay.

toner refill then power on printer show error card replace reset chip

I've seen a few of these and the easiest fix is to replace both the blower motor speed controller/resistor and the wiring harness connector. I've tried fixing the connector but the repairs don't last because of the heat generated at the connector if everything isn't just right. You can purchase the connector, which comes with color coded pigtail wires attached, from the dealer and it's a fairly easy and permanent fix. Hope this helps and good luck!

A J3 means the toner cartridge is not compatible. That is the what the J3 message means.
Make sure the correct cartridge has been installed. For example, a Pro16 Toner Cartridge looks very similar and will fit in the machine, but it will display a J3 fault. Install a known correct Toner Cartridge if you suspect the cartridge in the machine is the problem. If the wrong Toner Cartridge has been used, the correct cartridge needs to be ordered and installed in the machine
It is possible the chip on the back of the cartridge is bad. Have you tried reseating the cartridge? Maybe it is just loose.

your copier should be displaying a fault code, different codes need different reset codes - be specific

The fuser is not warming up.
On that machine under the web there is a thermal fuse on a white plastic mount, it has one screw through it.
It is most likely blown. Possibly caused by a jammed paper in the fuser.
That fusable link needs to be replaced.
