corner of the unit, and lower the belt unit flat inside the printer.
8.Turn the two fasteners (5) 90° to the right until they lock. This will secure the belt unit in place.
9.Replace the four image drums, complete with their toner cartridges, into the printer in the same sequence as they came out: cyan (nearest the rear), magenta, yellow and black (nearest the front).
10.Finally, close the top cover and press down firmly at both sides so that the cover latches closed.
FUSER REPLACEMENT
The fuser is located inside the printer just behind the four image drum units.
WARNING!
If the printer has recently been powered on, some fuser components will be very hot. Handle the fuser with extreme care, holding it only by its handle, which will only be mildly warm to the touch. A warning label clearly indicates the area. If in doubt, switch the printer off and wait at least 10 minutes for the fuser to cool before opening the printer cover.
Switch off the printer and allow the fuser to cool for about 10 minutes before opening the cover.
