After detecting near end, when the toner density is lowered to the
specified level or lower and the toner sensor detects toner LOW
continuously for a certain time, it is judged as toner end.

• When the developer (developer cartridge)/drum counter exceeds

the specified number of sheets.

• When the rpm of the developer cartridge/drum cartridge exceeds

the specified number.

If one of the above two exceeds the specified level, it is judged as
life end.
In an actual use, the ratio of the color output may be extremely
greater than the monochrome output, and vice versa.
For a document or data with monochrome and color components, it
may be outputted in the color mode in order to prevent against fall
in the job efficiency.
In addition to during the output operation, the developer cartridge
and the drum are rotated during the correction operation and the
warm-up operation.
Because of these factors, the consumption degree of the developer
cartridge and the drum cartridge cannot be determined only with
the print quantity. When, therefore, the number of rotations of the
cartridge exceeds the specified level, it is judged as life end.

The accumulated number of rotations of each developer (developer
cartridge)/drum can be displayed with SIM 22-1 as the reference
for the drum/developer (developer cartridge) life. The value dis-
played with SIM 22-1 indicates the reached level (%) when the
developer (developer cartridge)/drum life is 100%.

Example) Life 550K, used number of rotations 385K

385/550 x 100 = 70 (%)

After detecting near end, when the toner density is lowered to the
specified level or lower and the toner sensor detects toner LOW
continuously for a certain time, it is judged as toner end.

• When the developer (developer cartridge)/drum counter exceeds

the specified number of sheets.

• When the rpm of the developer cartridge/drum cartridge exceeds

the specified number.

In an actual use, in the correction operation and the warm-up oper-
ation as well as the output operation, the developer cartridge and
the drum rotate idly.
If the correction operation and the warm-up operation are made fre-
quently, idle rotations of the developer cartridge and the drum are
increased accordingly.
Because of these factors, the consumption degree of the developer
cartridge and the drum cartridge cannot be determined only with
the print quantity. When, therefore, the number of rotations of the
cartridge exceeds the specified level, it is judged as life end.

As the reference for the drum/developer (developer cartridge) life.
the accumulated number of rotations can be displayed with SIM 22-
1. The value displayed with SIM 22-1 indicates the reached level in
percent (%) when the developer (developer cartridge)/drum life is
100%.

Example) Life 550K, used number of rotations 385K

*2: When the black drum cartridge does not reach the life end and only the color drum cartridge reaches the life end, black/white print can be 

performed but color print cannot be performed.

• When the drum cartridge is replaced with a new one, the print counter, the accumulated traveling distance counter, the accumulated rotation

number counter, and the usage day counter are automatically cleared.

• If the above guidance does not disappear when the drum cartridge is replaced, SIM24-7 must be executed to clear the print counter, the
