AIO, Toner Packs
• Always store AIOs and toner packs in a cool, dark place.
• The service life of the AIO supplied with the machine is approximately 500 printed pages. This
should be installed at installation and used until it runs out.
• The service life of a replacement AIO is approximately 2,000/1,200 printed pages. But this will
depend on the image volume and density, number of sheets printed at a time, paper type and size,
and ambient conditions such as temperature and humidity. Also, toner quality may deteriorate if the
printer is not used for a long period of time.
• Encourage operators to have at least one replacement AIO on hand.
• For optimum printing results, use only the AIOs and toner packs (for refilling) recommended for use
with this machine.

• The number of pages that can be printed between the toner near end and toner end alerts is
approximately 100 pages.
