MX-7000N MAINTENANCE 9 – 5
The PM cycle means the replacement timing of periodic replace-
ment consumable parts and other parts for maintaining the perfor-
mance.
The PM cycle is specified only for B/W output. For color output, it is
used as a reference value.
[REASON]
Since the ratio of B/W to color differs depending on the user's oper-
ation scene and other conditions which varies every day, the PM
cycle cannot be specified in a certain cycle for color output.
Replacement of a PM item at the recommended life is performed
by the dealer's judgment or at PM call or at EM call.
Definition of drum life end
When the drum counter exceeds the specified level of 100% black
output or 100% full color output, it is judged as life end.
However in practice, wear cannot be specified by the number of
sheets of output because racing is increased in the tandem engine
by the mixing ratio of black and color outputs or when black output
is made in the color mode in ACS. For the reference of product
quality, wear is specified by the drum rotations. The rotation of the
MX-5500/MX-6200/MX-7000 series drum rotation is 840K.
The drum life is affected by the print quantity of one job. This is
because the actual life is determined by the rotations of the drum.
When the print quantity of one job is less than 6, the number of
rotations for one page is increased. As shown in the graph below,
therefore, the drum life quantity varies for each print quantity of one
job.

As a reference of the drum life, "Life meter" can be checked with
SIM22-1 according to each drum rotations.
"Life meter" indicates the remained life (%) of the drum with the
entire drum life as 100%.
(Example) If the used number of rotations is 550K:
SIM22-1 according to each drum rotations.
"Life meter" indicates the remained life (%) of the drum with the
entire drum life as 100%.
(Example) If the used number of rotations is 550K:
100 (%) - 550 (K rotations)/ 840 (K rotations) x 100 = 040 (%)
