Replacing the Laser Print Cartridge
When the laser print cartridge runs low on toner, the
printer’s Control Panel will display Toner Low. You
should replace the laser print cartridge soon after this
message appears to avoid loss of print quality. This is a
simple procedure, described on the following pages.
Do not expose the laser print cartridge to direct
sunlight or artificial light for more than 15 minutes.
Overexposure will permanently damage the
photosensitive imaging drum.
Do not open the drum shutter (see Figure 4.1 below)
or touch the green imaging drum surface.
