Open and close the access door on the printer. When it runs to check itself, does it squeak?

 

If yes, start removing each of the toner cartridges one by one and closing the door after each to let the printer run a check and see if the squeaks stay or stop. Whichever cartridge is pulled out and the squeaks stop, is the one causing the problem. If, however, you get them all removed and it still squeaks, then you're looking at something else causing it. It could be the fuser, ITB unit, any one of the number of plastic rollers in the paper path, or even maybe the paper path drive roller's shafts in plastic bushings. Troubleshooting which will be tricky.
