3.  Definition of developer/drum life end
When the developer/drum counter reaches the maximum printable
count.
When the developer/drum rpm reaches the specified count.
When either of the above reach the specified count, it is judged as life
end.
In an actual case, the ratio of monochrome output and color output
may differ greatly.
When data of mixed documents (monochrome and color) are output,
monochrome document data may be output in the color mode in order
to prevent against fall in the job efficiency. (ACS auto color selection).
In addition, when correction or warm-up operation is performed as well
as output operation, the developer and the drum rotates.
Therefore, the developer/drum consuming level cannot be determined
only by the copy/print quantity. When, therefore, the rpm reaches the
specified amount, it is judged as life end.
To check the developer/drum life, use SIM22-13.
However, when the copy/print quantity is large and the developer/drum
counter reaches the maximum printable quantity even if the rpm does
not reach the specified amount, it is judged as life end.
The table which shows the relation between the standard printable
quantity and the maximum printable quantity in the specified rpm
amount is as follows.
* Standard printable quantity means the printing quantity under the
specified developer/drum count by using the specified test data
