This SP saves the rotation count (sec.) for the OPC
when a re-filled cartridge is detected. When a
re-filled cartridge is detected, the value for the OPC
rotation count is copied from the AIO ID Chip and
saved this SP.
Note:
If the cartridge is not installed, if the AIO is not
set properly, or if the front door is open, no value
will be displayed because the machine cannot
communicate with the AIO.
The counter increments by "1" for every 6 sec.
of drum rotation time.
To calculate the actual time in sec., multiply the
displayed value by 6.
This SP displays the length of the service life that
remains for the OPC.
The value is read from the AIO ID Chip.
The number displayed indicates as a
percentage the amount of time remaining for the
OPC based on the number of drum rotations.
If the cartridge is not installed, if the AIO is not
set properly, or if the front door is open, no value
will be displayed because the machine cannot
communicate with the AIO.
Important Note: This SP reads only the engine
information. This information is not sent to the
controller.
