Confidential
To avoid problems caused by abrasion of the developer roller surface or deterioration of the
toner sealing, the machine prohibits printing when the number of rotations of the developer
roller reaches the limit, displaying a message prompting the user to replace the toner cartridge
before the toner runs out. The table below shows the limit of the number of rotations of the
developer roller.
<Life of toner cartridge>
The life of the toner cartridge based on the number of rotations of the developer roller (point
3 on the previous page) varies depending on the average number of pages printed per job
(see the table below). The number of printable pages is larger when performing continuous
printing in one job because deterioration of the developer roller is lower.
* The number of rotations varies according to individual differences in machines and
installation environment. The above data is for reference.
