2.6 Life of Toner Cartridge and Drum Unit
■
Life of toner cartridge
<Method of detecting toner life>
There are two messages, which are displayed on the LCD to indicate that toner reaches
its life: “Toner Low” and “Replace Toner.” While “Toner Low” is displayed on the LCD
when the toner sensor detects a certain amount of toner is used, “Replace Toner” is
displayed on the LCD when the toner sensor detects that toner is used up or when the
number of rotations of the developer roller reaches its life.
- Detection by the toner sensor
This machine has a function to detect the remaining toner by checking the level at which
toner in a cartridge interrupts light using a transmissive light sensor.
- Detection by means of rotation rates of the developer roller reached its upper limit
This machine has a function to detect when the number of rotations reaches the upper
limit before the developer roller is worn out and becomes unusable.
<Relationship between printable pages of the toner cartridge and remaining toner>
The life of toner cartridges when making prints of the print pattern specified by ISO/IEC 24712
is shown in the table below. (At the point of
in the figure above)
To avoid problems caused by the worn-out of the developer roller surface and deterioration of
the toner ceiling, “Replace Toner” message is displayed and the print operation is prohibited
when the number of the rotations of the developer roller reaches the upper limit even if toner
remains. The upper limit of the number of the rotations of the developer roller is shown in the
table below.
Memo:
When the number of rotations of the developer roller reaches the
cartridge life end, “Replace Toner” is
displayed even if toner remains.
