I tried the reset fuser and your instructions do not work for the 3600n. reset supplies is under another category and new fuser kit is not an option?????

immediatly below the fuser unit/ above the image transfer belt inside the covers are the colour calibration sensors- they have mylar windows which get coated over time- clean with isopropyl- the sensors are looking vertically down and are approx 5x15mm is size there is one sensor to the left and one to the right, if after cleaning these the error still exists- try replacing the ITB and try again

59.xx error main motor failed to reach rotation speed in a given time:-
have you recently changed a toner cartridge? is it 3rd party?
remove all toner cartridges and then switch power on to printer - it should turn over then ask for toners to be inserted, if so the problem probably lies with a toner cartridge
if the toners prove to be ok then the issue may be the Developer lift plates ( front/rear) which tend to snap after a while not an expensive repair but time consuming..fuser units on this machine dont generally give main motor failures neither does the transfer belt. If I was attending this call I would definatly have a full set of spare toners and the dev lift plates to hand as this would most likely be the fix

This is probably because of a defect or missing RAM chip. Try replace the RAM chip on formatter board or call for service if the product is still under warranty. Check for yourself HERE.

Good luck.
