yield toner) A4 or Letter size single-sided pages at 5% coverage. In the case of low-duty printing,
“Toner Life End” is indicated by “TONER LIFE END” message appears on the LCD panel before
the toner runs out because the developer roller surface or other toner sealing is worn out due to a
rotation of the rollers. The upper limit of the drum rotation is 44,000 = 4,000 sheets x 11 rotations
(standard toner), 92,400 = 8,400 sheets x 11 rotations (high yield toner).
The following graph shows the number of printable pages in the case of A4 printing.
