Cartridge Life - Brother DCP-9055CDN Service Manual

<Cartridge life>
The cartridge life (at the point of
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.
Memo:
- The number of rotations of the developer roller per A4-size page*:
First page
Second page and after (in the case of
continuous printing)
- The number of rotations of the developer roller for each operation*:
Warm-up operation
Adjustment of color registration
Adjustment of color calibration
Number of idling rotation when the
machine is turned ON (Worst value)
* Since the number of rotations varies according to individual differences between
machines and the environment, consider it as a reference value.
Note:
The numeral values provided in this page are as of August 2010. These values are subject
to change without prior notice.

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.)
