 The print cartridge is called the AIO (all-in-one) throughout
this course.
 All models in the series use the same AIO.
 There are no serviceable parts inside the AIO.
 Disassembly of an AIO is never required.
 When the AIO runs out of toner, the toner waste tank can
be emptied and the toner supply tank can be refilled.
 All models except the the Europe and N. America models
(M145, M146, M147, M148, M149, M150, and M151): An
AIO can be refilled up to three times (this is the
approximate service life of the drum). The refillings greatly
extend the service life of the AIO.
 The AIO can be easily removed and replaced by the user.
 The AIO has an ID chip which helps the machine to detect
when an AIO is set and when a new AIO has been installed.
Slide 75
 The machine detects that an AIO has been refilled when toner end is no longer
detected, but the ID chip is not for a new AIO.
