1. The Unit Life Manual
NOTES
• The life specifications values represent the number of copies made or figures equivalent to it when given conditions are met. They can be more or less depending on the copier operating conditions
of each individual user.
• The initiation of a new copy cycle is inhibited upon 1K after a near life condition has been detected for all units (except the Toner Bottle and Waste Toner Bottle).
M: minutes
✽
1: As a rule, the Fusing Unit is to be replaced at the same time that the Fusing Web Unit is replaced a sixth time (17K × 6 = 102K). If the Fusing Web Unit is replaced before 17K is reached, there
will be a discrepancy in the replacement cycle, resulting in a near life and life value ranging between 90K and 110K.
✽
2: The life of the Transfer Belt Unit is controlled based on the number of copies made. The life counter gives a time value display.
✽
3: The life of the Imaging Unit is controlled based on a time value. The life counter gives a time value display.
