SOURCE: 980: Fatal Error
From the Service Manual:
*Error by media
clinging to the fuser
*Media has clung to the fuser.
Replace the fuser unit.
Before you replace the fuser, take it out and check for a piece of stuck label, paper, etc. You can spin the fuser roller by turning the gear on the side.

Service Call 188: Error: Sub-CPU Communication Error
1- Check the connection of the S2M board.
2- Replace the S2M board.
If the problem does not go away after a reboot you'd better call Oki (it should have a 3 yr. waranty) or an experienced oki technician.
This is not something you should want to fix yourself. The replacement of the s2m board is not an easy task (even for an experienced mechanic)

SOURCE: SERVICE CALL ? 980 ? Fatal Error
I was able to reset my Fatal Error 980 code on my C5800. There is only
two wires coming from that connector and not four at the bottom of the
fuser. That is pin 2 and 3. 4 and 5 is still the fuse but there are no
wires there, just the 2 pins. What you have to do is make a fuse by
connecting pin 4 and 5 together with a piece of wire and break the wire
after a few seconds after powering up. This will reset the Fuser
counter back to 100%. DO NOT DO THE NVRAM RESET, THAT WILL ERASE YOUR
NETWORK FEATURE. Here is the step by step of what I did.
1)Take out the Fuser and lay the two blue levers flat and remove them.
2)remove the two silver screws and separate the casing.
3) Remove the two black screws from the connector at the bottom of the fuser closest to the edge.
4)Unravel and loosen the wires so you can pull that connector out a few inches so you can get a couple of wires in there. You will see what you need to loosen to get the connector out far enough, really easy.
5)Insert a wire into each of the two holes on the back of that connector. Its pretty simple to see where they go, 2 and 3 have wires going in, 4 and 5 dont which is the fuse. After you get the wires in the 2 holes, check for continuity from the end of the wires and the terminals if you can. Make sure the wires are long enough to hang out the case. Use the thinnest wires you can find.
6)Run the wires out of the case and put the case back together and put the fuser in. Twist the two wires together and power up the machine. As soon as you here the first motor,which is about 5 seconds, pull the wires apart and BAM, you just reset the fuser back to 100% and cleared the "980" Fatal Error. You could always put a miniature fastblow fuse in instead of using the wires but that would be tedious to me.Good luck

SOURCE: OKi C5800ldn 231: fatal error 03
I have the Oki 5650 which had been great for about 18 months. Then found that the C cartridge was showing error as 'not installed'. After much fiddling about with it and checking on the internet I can now rectify this by either pushing down on the top of the printer while it boots up, or removing the small chip on the left top of the toner (make sure you have 'earthed' yourself to prevent any static damaging the chip when you handle it!) and taping securly onto the top of the cartridge above the chips proper slot. This now has been working OK for 6 months. Strange how this only affects the C cartridge (which has also been replaced and had the same problem). I suspect that the printers RFID chip reader for the C cartridge is having problems reading the chip and moving the chip closer to the reader by either taping to the cartridge top of puching on the top cover while printer boots up resolves the problem (for now anyway!) This can also trigger the 'service call 231 fatal error 03' message which also disappears if you follow the above procedure.
Hope this helps you.

Check the polygon motor operation with
Check connector/harness of polygon
Replace the polygon motor.
Replace the MCU PWB.
If the polygon motor isn't working then you will neeto buy a new Laser Unit. They can be expensive if you can get one. To replace it will tak alot of disassembly as well. Might be better and more cost effective to get a new machine.
