Switch off the printer and allow the fuser to cool for about 
10 minutes before opening the top cover.

Press the top cover release button and open the printer’s 
top cover fully.

Pull the coloured lever on the right side of the toner 
cartridge towards the front of the printer to close the 
cartridge then remove the used toner cartridge.

Follow the installation instructions on or inside the box 
containing the new toner cartridge to install the new 
cartridge.

Gently wipe the LED array surface with the LED lens 
cleaner that came with the new toner cartridge or soft 
tissue.

Close the top cover and press it down to latch it closed.

The life of an image drum depends on a number of factors, 
including temperature and humidity, the type of paper used, and 
the number of pages per job.

The image drum should last approximately 25,000 pages 
continuous printing. This number is approximate because 
different numbers of pages are printed each time and the 
environmental conditions and the paper type used may vary.

When the drum reaches 90% of its life, a CHANGE DRUM 
message is displayed in the printer Status Monitor. Also, the Error 
LED indicator blinks fast when the image drum requires 
changing. Change the image drum when the print becomes faint 
or begins to deteriorate.
