3. Developer/Drum life end definition

• When the developer/drum counter reaches the specified level.
• When the developer/drum rpm reaches the specified level.
When either of the above reached the specified level, it is judged as life end.
In an actual case, 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 level, it is judged as life end.
To check the drum and developer life, use SIM22-1/SIM22-13.
