3.4.2 Toner Life End
A new toner cartridge can print with standard toner approximately 2,500 (black), 1,500 (yellow,
magenta, cyan), with high capacity toner, approximately 5,000 (black), 4,000 (yellow, magenta,
cyan) in the case of A4 or Letter size single-sided pages at 5% coverage.
If printing A4 paper at 5% print coverage or less, the “Toner Life End” message is displayed
before the machine runs out of toner, and the printing operations are inhibited, in order to avoid
the problem due to wear on the surface of the developing roller, deterioration of the toner seals
or the like. The upper limit of the rotation rate of the develop roller is 55,500 rotations (3,000
pages x 18.5 rotations) for standard black toner; 33,300 rotations (1,800 pages x 18.5
rotations) for standard toners of yellow, magenta and cyan. In addition, the limit is 111,000
rotations (6,000 pages x 18.5 rotations) for high-capacity black toner; 92,500 rotations (5,000
pages x 18.5 rotations) for the high-capacity toners of yellow, magenta and cyan.
The following graph shows the number of printable pages in the case of A4 printing.
Memo:
The number of rotation of the developer roller per page is as follows.
- One printed page only or the first page of continuous printing = 18.5 rotations
- After 2 pages for continuous printing = 5.6 rotations
Number of idling rotation when the machine is turned ON = 12 rotations
