3.4.2 Cartridge life
A new toner cartridge can print approximately 3,000 (standard toner) or approximately 8,000
(high yield toner) A4 or Letter size single-sided pages at normal duty (ISO/IEC19752). In the
case of low-duty printing, if the number of printed pages are reached the cartridge life,
"Replace Toner" message appears on the LCD before the toner runs out because the
developer roller surface or other toner sealing is worn out due to a rotation of the rollers.
<Cartridge Life>
The toner cartridge life varies according to the average number of printing per job.
As the deterioration of toner will be less in case of printing more pages continually once time
than usual, the more printing pages per job, the more printable pages of toner cartridge.
Increasing the number of times of power switch ON and warming operation in company with
opening or closing cover will also cause the deterioration of toner, so the more frequency
those operations be taken, the less pages the toner cartridge can print.
Memo :
• If reached the cartridge life end, "Replace Toner" message appears even if the
toner is contained.
