I cannot understand why you are using sublimation paper on an LED printer which uses toner. I always thought that sublimation printing is used with dye and not toner. Why it worked in the first place is odd. Anyway I reckon you have worn out the fuser and or the fuser is not reaching temperature which is why its not fusing correctly.

Oki is forcing you to buy a new fuser. If fuser roller, film and thremistors are still in perfect shape, reset is possible with new OEM FB fuse

I expect you have an extra tray fitted. This error refers to this option. Turn the power off and lift the printer off the second tray .Now turn it back on and it should print ok. If so then throw away the optional 2nd tray as it has gone faulty.
