Performing the following operations deteriorates the developer roller: warm-up operation
after power ON or opening/closing cover, paper tray lift-up operation, and fuser unit warm-up
operation. Therefore, if these operations are performed frequently, the life of toner cartridges
becomes shorter. (The table below shows the worst-case scenario where warm-up operation
after power ON and fuser unit warm-up operation (max.) are performed before printing.)
<Relationship between average number of pages printed per job and life of toner cartridges>
(40/42PPM model)
Average pages printed (page/job) 1 2 3 4 5 6 7 8
Cartridge life (Starter) 2710 3636 4104 4386 4575 4710 4812 4891
Cartridge life (Standard) 3484 4675 5277 5640 5882 6056 6187 6288
Cartridge life (High) 6581 8831 9967 10653 11111 11439 11686 11878
Cartridge life (Super high) 9290 12468 14072 15039 15686 16150 16498 16769
<Life of toner cartridge when warm-up operation after power ON and fuser unit warm-up
operation (max.) are performed before printing>
(40/42PPM model)
Average pages printed (page/job) 1 2 3 4 5 6 7 8
Cartridge life (Starter) 712 1261 1698 2054 2349 2598 2811 2995
Cartridge life (Standard) 915 1622 2183 2641 3020 3340 3614 3850
Cartridge life (High) 1729 3063 4124 4988 5705 6309 6826 7273
Cartridge life (Super high) 2441 4324 5822 7042 8054 8907 9637 10267
Note:
• The above two data applies to 40/42PPM models (A4/Letter). For 38/40PPM and 36/
38PPM models, data for continuous printing is different due to difference in the printing
speed.
