3.4.1 Toner life end mode
A new toner cartridge can print approximately 3,500 (standard toner) or approximately 7,000
(high 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 lighting Toner LED (HL-5240/5250DN) or “TONER
LIFE END” message appears on the LCD panel (HL-5270DN/5280DW) 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 46,200 = 4,200 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.
