REPLACING CONSUMABLE ITEMS
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 af fected 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 th e image drum, the printer 
displays messages to repl ace 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).
Only use genuine Oki Original  consumables to ensure the 
best quality and performance from your hardware. Non 
Oki Original products ma y damage your printers 
performance and invalidate your warranty.

TONER CARTRIDGE REPLACEMENT
The toner used in this printer is a very fine dry powder. It is 
contained in four cartridges: one each for cyan, magenta, yellow 
and black.
Have a sheet of paper handy so that you have somewhere to 
place the used cartridge while you install the new one.
Dispose of the old cartridge responsibly by placing it inside the 
pack that the new one came in. Follow any regulations, 
recommendations, etc., which may be in force concerning waste 
recycling.
If you do spill any toner powder, lightly brush it off. If this is not 
enough, use a cool, damp cloth to remove any residue.
Do not use hot water, and  NEVER use solvents of any kind. They 
will make stains permanent.
1. Lift the scanner.
CAUTION!
To avoid toner wastage an d possible toner sensor 
errors, do not change the- toner cartridge(s) until 
“TONER EMPTY” is displayed through the Status 
Monitor.
WARNING!
If you inhale any toner or get it in your eyes, drink a 
little water or bathe your eyes liberally in cold water.
