< How to calculate Drum Unit Life >
The number of drum rotations per one page printing is about 15 rotations.
(Page counter reduced by the number of drum rotations) =
(the number of drum rotations) ÷ 15
- The number of drum rotations per one page printing continuously = 4.3
rotations.
- The number of drum rotations while warming-up = 9 rotations
Example:
1 page/job
2 pages/job
18 pages/job
If printing 1 page per job with cold start, the drum unit life is decreased
earlier.
(ii) Counter information, history information
The counter and history information related to the following term are
included. When it reaches the maximum count, each term is no longer
counted.
• Device status
The total number of pages printed. The maximum count is 1 million
pages.
• Total pages printed (TRAY)
For Manual Feed Slot and TRAY, it is indicated only when they are

The number of pages calculated from drum rotations
Cold start (page)
(9 + 15) / 15 = 1.60
(9 + 15 + 4.3) / 15 = 1.88
(9 + 15 + 4.3 x 17) / 15 = 6.47
8-10
Hot start (page)
15 / 15 = 1
(15 + 4.3) / 15 = 1.28
(15 + 4.3 x 17) / 15 = 5.87
