<Cartridge life>
The cartridge life (at the point of in the figure above), which depends on the upper limit
of the number of rotations of the developer roller, varies according to the average number
of print pages per job. (See the table below.) The number of printable pages is larger
when making continuous prints in one job because deterioration of the developer roller is
low.
<Relationship between average print page per 1 job and life of toner cartridges
>
The developer roller also rotates for the warm-up operation, color registration adjustment
operation, and developing bias adjustment operation when the power is turned ON and when
the cover is opened or closed. Therefore, when these operations are frequently performed,
the life of toner cartridges is shortened. (The table below shows the worst case in which the
warm-up operation, color registration adjustment, and developing bias adjustment are
performed when the power is turned ON.)
<Cartridge life in the case that the power is turned OFF/ON and adjustment is performed before printing>
Memo:
- The number of rotations of the developer roller per A4-size page*:
- The number of rotations of the developer roller for each operation*:
* Since the number of rotations varies according to individual differences between
machines and the environment, consider it as a reference value.
