<How PM Counters are Managed>
There are 2 possible ways to manage the PM counter; either using the Distance Counter or the
Page Counter.
Display of the counter values can be selected by specifying SP7943-001 (Drive Distance PM
mode).
1) SP7943-001= 0 Æ Counter values will be displayed in Drive Distance
2) SP7043-001= 1 Æ Counter values will be displayed in Page Counter
3) Default is set to 1.
4) Web Total: Page Counter is displayed in SP7913 regardless of the setting made in SP7043-001.
Example 1
When Fusing Unit #2 is installed and SP7943-001 = 0:
* Values in SP1-210-016 to SP-210-021 are displayed in SP7621-115 to SP7621-129
* The value in SP1210-028 is displayed in SP1903.
Example 2
When Fusing Unit #3 is installed and SP7943-001 = 1,
* Values in SP1-210-035 to SP-210-040 is displayed in SP7621-115 to SP7621-129.
* The value in SP1210-041 is displayed in SP1903.
The system will only count up the counters for the fusing unit that is currently installed.
Counter values of the reserve fusing unit(s) will remain as they are.
For example, if the system is operated with Fusing Unit #1 installed, counter values of SP1210-003
to SP1210-015 will be counted up and counter values of SP1210-016 to SP1210-054 (for Fusing
Unit #2, #3 and #4) will remain the same.
Also, the counter values are reflected in the same manner when the PM Counter is cleared.
