lows.
The number is printed on the right under side of the back surface of
the developer bag.

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/drum counter exceeds the specified number

of sheets.

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

ified number.

In an actual use, in the correction operation and the warm-up oper-
ation as well as the output operation, the developer and the drum
rotate idly.
If the correction operation and the warm-up operation are made fre-
quently, idle rotations of the developer and the drum are increased
accordingly.
Because of these factors, the consumption degree of the developer
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 life. the accumulated num-
ber of rotations can be displayed with SIM 22-1. The value dis-
played with SIM 22-1 indicates the reached level in percent (%)
when the developer/drum life is 100%.

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

385/550 x 100 = 70 (%)
