In regard to "49.2F80 Service Error" I would suggest the following:
Power off the printer.Unplug the AC power cord, USB or Network cables.Check for any paper jams, pull out each tray to clear any obstructions. Remove and re-insert the ink cartridge, it should be snug and fit evenly in the cartridge repository.Wait 60 seconds with the printer powered off for any resident electrical charge to dissipate.Plug in cables with the AC power cord plugged in lastTurn on the printer.After the printer completes it's power cycle, any print jobs will print out. I fixed this exact error code with the steps outlined above.

It is passable the grinding noise is coming from one of the toner cartridges in the printer.
Check for any toner cartridges which are stiff or difficult to turn by hand
Replace and refilled toners or compatible toners with original manufactures toners.
If you have alternative toners available replace each toner in turn to see if the cause can be identified to a particular toner.
