MX-5141N  CONSUMABLE PARTS  3 – 5

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 out-
put, 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 deter-
mined 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
with the color ratio of 30% under the following intermitment sheet.
