This section explains how to replace consumable items when due. 
As a guide, the life expectancy of these items is:

Toner — 1,000 A4 pages at 5% coverage, which means 
that 5% of the addressable print area is printed with this 
colour. Toner life is directly affected by coverage, e.g. at 
10% coverage there is sufficient toner for 500 pages.

The MFP is shipped with sufficient toner for 1,000 A4 
pages. 500 A4 pages worth of this starter toner is 
used to charge each image drum. Therefore, as the 
toner is released into the image drum, the printer 
displays messages to replace toner well in advance.

Replacement toner does have to charge the image drum.

Replacement toner is available in High Capacity as well as 
standard cartridges.

Image drum — 15,000 pages (calculated on typical office 
usage of 3 A4 pages per job).

Transfer belt — Approximately 50,000 A4 pages at 3 
pages per job.

Fuser — Approximately 30,000 A4 pages (C3520), 50,000 
A4 pages (C3530).
