o
[Life].
• Life specification value means an actual life terminated when prints are made under the
conditions as defined in the next section, “Conditions for life specifications values.”
The actual life may vary greatly depending on how the machine has been used and other
factors.
<Imaging unit life value *4>
*1: A waste toner full condition is detected with detecting the actual waste toner emissions.
*2: Once the toner-full is detected, it has to be replaced with the new waste toner box in
order to reset.
*3: The initiation of any new print cycle is inhibited when reaching the max. life value.
*4: The mark “M” is indicated the value of the number of distance through which the PC
drum has run translated to a corresponding value of the number of hours and the value.
*5: “Normal” and “Long” are the settings provided in [Service Mode]

Waste toner
box
The waste toner full sensor detects the amount of toner
accumulated in the waste toner box and sends a signal that
determines the end of the waste toner box life.

Transfer belt
unit
Comparing the number of printed pages *6 with the number
of printed pages calculated based on how long the transfer
belt has run, the machine detects the end of unit life when
either of them reaches the set value shown on the right.
(However, to detect whether the unit reaches the max. life
value, the machine uses only the number of printed pages
calculated based on how long the transfer belt has run.)

C,M,Y
Comparing the PC drum rotation time with the PC drum
rotation time calculated based on the number of printed
pages *6, the machine detects the end of unit life when
either of them reaches the set value shown in the table
below.
* The PC drum rotation is calculated based on the distance
the PC drum has run.
See the imaging unit life
