The PM cycle means the replacement timing of periodic replace-
ment consumable parts which are required for maintaining the per-
formance.
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 which varies every day, the PM cycle cannot be speci-
fied 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.
[Life end definition of a OPC drum ]
When the OPC 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 rotations
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 OPC drum rotations. The rotation of the MX-5500/
MX-6200/MX-7000 series OPC drum rotation is 840K.
The OPC drum life is affected by the print quantity of one job. This
is because the actual life is determined by the rotations of the OPC
drum.
When the print quantity of one job is 5 or less, the number of rota-
tions for one page is increased. As shown in the graph below,
therefore, the OPC drum life quantity varies for each print quantity
of one job.
"Life meter" can be checked with SIM22-1 according to each OPC
drum rotations as the OPC drum life.
"Life meter" indicates the remained life (%) of the OPC drum with
the entire OPC drum life as 100%.
(Example) If the used number of rotations is 550K:
100(%) – 550 (K rotations) / 840 (K rotations) x 100 = 040 (%)
