DX-C401  CONSUMABLE PARTS  2 – 3

The indications of a lot number are the same as those of the devel-
oper cartridge.

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 (%)
