
PM parts yield is based on the page counter (K) when
the customer prints using the target conditions.

Ch-C1 Pro: 70% color ratio, 26 P/J

Ch-C1 Office: 30% color ratio, 5 P/J

But, for most PM parts, the yield depends on running
distance

See the formula below for how this is calculated.

So, a function was added to display the estimated PM
yield, in which the running distance is included.
Page Counter and Running Distance
Running Distance (m) (SP7-944-001~127)
= Motor rotation time (s)
×
Paper speed (mm/s)/1000

Motor rotation time: This is the accumulated time that the motor that drives
the PM part has been rotating.

Similarly to the Taurus, CH-C1 applies the running distance calculation to
display the usage rate and remaining days of parts.

With this system, PM can be scheduled with more accuracy according to
machine usage conditions unique to every user.

Please refer to the usage rate and remaining days when scheduling PM for
the CH-C1.
Note: Running Distance Data

Since the PM parts yield is determined by given conditions (e.g., CH-C1:
A4LEF, 26P/J, FC70%, etc), if a machine is used in an unexpected manner,
parts could reach their life before the prescribed yield (EM), or on the
contrary, could exceed the prescribed yield.

However, if a machine refers to the running distance of the parts (which is a
calculation based on the total number of revolutions made by the parts), PM
can be carried out at more precise timing because the running distance
reflects the actual status of the machine.
