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.)

• The above two data applies to 40/42PPM models (A4/Letter). For 38/40PPM models,
data for continuous printing is different due to difference in the printing speed.
