Note 1: Replace when the "TONER EMPTY" message displays. A guideline for the
replacement is 21,000 pages (A4 size, 4% coverage).
Note 2: Replace when the "WASTE TONER FULL" message appears. A guideline for
the replacement is every 90,000 pages (A4 size, 4% coverage).
Note 3: Inspect every 150,000 pages; clean if needed. Replace at 300,000 pages or
sooner if print quality is no longer acceptable. Drum life depends upon media used
and proper maintenance and operation of the printer. Print media other than bond
paper (e.g. labels, card stock, plastic or vinyl) can reduce drum life as much as 50%.
