Regular maintenance
You can perform most regular maintenance tasks, replacing toner cartridges,
fuser oil, the photoconductor cartridge, and toner disposal boxes. In addition,
when the fuser wears out, you can replace it yourself, following the
instructions in Appendix F (or call an Apple-authorized service provider to
do it for you).
For information about ordering the replacement supplies, see Appendix A.
Low toner
The toner cartridges hold the toner powder that forms the printed images.
Each cartridge should yield about 4,000 pages. If you print many graphic
images, you may need to change cartridges more often. If your pages start to
look too light, or if you see thin vertical white lines in dark images, it may be
time to change the cartridge. Also, the status panel lets you know when toner
is low.
When you see these lights, it can mean one of two things:
m The toner powder needs to be redistributed inside the toner cartridge.
m The cartridge needs to be replaced.
If the lights come on in the middle of a printing job, and the output is still
satisfactory, continue printing if you wish. You won’t harm the printer by
doing so.

When toner is low, the Alert light glows
and a toner light comes on.
A light indicates
which color is low.
