AR-5726/5731 CONSUMABLE PARTS 3 - 3
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.
