Replacing the Laser Print Cartridge
When the laser print cartridge runs low on toner, the
printer’s Control Panel display will read
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 blue imaging drum surface.
