Your indication regarding the 100% does not necessarily indicate a damaged chip (sensor).
Many chips do not work by actually sensing the toner but by usage or other tricks.
We cannot be sure about what happened but replacing the drum and affected items
should solve the problem. Needed parts may be found at

You need to do s head clean.
This could take 2 or 3 goes but should fix it you will find head clean in the maintenance settings.
It eats the ink so only do as you need.
let me know how it goes.

If you printer has an additional memory card fitted then remove it (powered off of course) and turn on and see what happens. If the fatal error is still there then with the age of the machine (getting on in years) it is better to replace it as the error refers to the cpu in the control board and that's expensive on older machines to replace.

the best soloution is to replace the unit with a brand new one as reset fuses are difficult to work with on fuser units but if you search the internet you might be able to find a reset kit from alibaba or amazon

Amber's solution worked on an oki c5150 as well as on her 5500.
At first, I got into other menus and did not see what she'd described. I cancelled out, then re-ran her procedure following its steps EXACTLY... At the very end, I may have seen one additional message - "EXECUTE" - which I "entered" to launch the process. Printer now works while I find instructions on how to replace "just the drum".

The OEM drum assembly is very easy to change but costs about $125. I found (on Universal Ink & Toner) a drum-only replacement for $30, but there was no instruction sheet with it. This solution has allowed me to keep working while I figure out how to install the new drum. Print quality was excellent right up until the manufacturer's internal counter shut printing down. Quality remains excellent after applying the above solution.

probably one of colour cartridges (usually not original from OKI) is updetting the printers logic Swap they around (even if you have to use old cartridges), find offending one and replace.

Press the OPEN button and open the top cover
Take out the image drum unit, place it on a flat surface, and cover it with black paper.
Remove any jammed paper in the direction of the arrow.
Remove in the direction of the arrow any paper jammed the inside front of the printer.
Pull out toward the front of the printer any paper jammed at the fuser unit, with the fuser unit lever (blue) left turned in the direction of the arrow.
Install the image drum unit in the printer so as to situate the K toner cartridge toward the front of the printer.

Inkjet printers need to be used frequently to prevent ink drying out and blocking the print head nozzles.
If the print head cleaning maintenance routine does not clear the blockages, then print head needs replacing, but it may be expensive.
It may be more cost effective to buy a later model and better printer than replace the print head.
