Concept of parts life
3.4.1
Life value of consumables and parts
• The life counter value of each materials and parts is available from [Service Mode] →
[Counter] → [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.
• "M" refers to the rotation time of each unit.
Description
Waste toner
The waste toner full sensor
box
on the front side relay board
detects the amount of toner
accumulated in the waste
toner box and sends a sig-
nal that determines the end
of the waste toner box life.
Fusing unit
When the number of printed
pages *4 reaches the set
life value shown on the
right, the end of unit life is
detected.
Rotation time for the fusing
unit is also counted for con-
trol's sake, but not used for
detecting life.
Transfer belt
Number of prints *4 and
unit
rotation time of the transfer
belt are counted, and
detected when one of those
two reaches to the life value
shown on the right.
Transfer
Rotation time of the transfer
roller unit
belt is counted, and
detected when it reaches to
the set life value shown on
the right. *5
Ozone filter Rotation time of the transfer
belt is counted, and
detected when it reaches to
the set life value shown on
