Replacing Toner Cartridges
Your printer uses four toner cartridges: one each for cyan,
magenta, yellow and black. If purchasing less than a complete
set, ensure you are purchasing the colour you require. This is
clearly indicated on the box.
Always use genuine OKI consumables with your printer.
These come in the familiar OKI red and white boxes and
are designed and manufactured specially for use in OKI
printers.
Genuine OKI toner is made from non-toxic materials and is
perfectly safe to use, provided you follow a few basic safety
rules.
1. When removing old toner cartridges from your printer you
will see the toner powder on top of the image drum cartridges.
Take care to avoid performing this task in a draft, and do not
blow on the powder, as this may cause a toner cloud. If you
inhale such a cloud, seek a clean fresh air environment, and
take a few deep breaths. If you continue to experience any
discomfort seek medical advice.
2. If you spill any toner on your skin or clothes, brush it off. If
necessary, rinse in cold water. Do not use hot water, since
the application of heat might make the marks permanent.
3. Do not attempt to clean spilled toner with any solvent or
spirit-based solution, as this may partially dissolve the toner
and cause permanent marking.
4. Take the new cartridge out of its box before you remove
the old one. The new cartridge comes with a plastic bag
which can be used to wrap the old cartridge for disposal.
5. Do not smoke while changing the toner cartridge. If you do
accidentally cause a toner cloud, as with all fine particle
clouds, it could become flamable.
When to Change a Toner Cartridge
The printer will display a message when any toner cartridge is
within about 100 pages of the end of its life. The display will
also indicate which colour is running out. You can normally
expect a toner cartridge to produce about 3000 pages at 5% print
density (this is a typical density for text pages).
There is no hard and fast rule, since toner life depends very much
on image content. Also, when installing a new image drum, the
first toner cartridge will run out more quickly, because the drum
reservior must fill when new.
