Page Counter and Running Distance
 PM parts yield is based on the page counter
 But, for most PM parts, the yield depends on
 So, a function was added to display the
Running Distance (m) (SP7-944-001~127)
= Motor rotation time (s) × Paper speed (mm/s)/1000
Slide 145
 Motor rotation time: This is the accumulated time that the motor that drives the
PM part has been rotating.
 The machine 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.
Note: Running Distance Data
 Since the PM parts yield is determined by given conditions (e.g., 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.
