<Life of Toner Cartridge>
This product detects the remaining toner only by the dot count and the number of
rotations of the develop roller. The function to detect by the light sensor is not
installed. As this printer is not equipped with a toner sensor as conventional models
are, it manages the level of remaining toner by dot count during printing and the
number of rotations of the develop roller. Therefore printing may stop with the error
message “Replace Toner” even though some toner remains. Even if “Replace Toner”
is displayed on the printer, printing can be continued if the user chooses to change the
mode to Continue Mode. In Continue Mode, however, the printing result when the
toner runs out is not assured, meaning that the user shall be responsible for it. In
addition to this, even when the mode is set to Continue Mode, printing stops when the
number of rotations of the develop roller reaches the upper limit, and remains stopped
until the toner cartridge is replaced to prevent any problems, such as toner leakage.
The life of the toner cartridge 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 develop roller is low.

The develop roller also rotates for the warm-up 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 is performed when the power is turned ON.)
