The end state is determined when the count exceeds the threshold setting of SP7-940-002, SP7-941-002 set for either paper sheet count or distance count (distance is calculated from the operation time of the drum motor (M3)).
The near-end threshold count setting is determined for either the paper or distance count as described below.
- Near-end threshold (sheet count):
End threshold (sheet count) - Number of days to near-end*1 x APV
Calculated with average print volume (APV), the average number of sheets printed every day. - Near-end threshold (distance):
End threshold (distance count [mm]) - Number of days to near-end*1 x APV
Calculated with the average print volume (APV), the equivalent distance traveled for average print volume, the average number of sheets printed every day.
*1: Number of days to near-end SP settings
| SP7-952-002 (Days Before End: PCDU) | Days before near-end |
|---|---|
| 0 Early | 7 days |
| 1 Normal | 5 days (default) |
| 2 Late | 3 day |
