5. Maintenance

This chapter explains how to replace consumables and maintenance units, clean the printer, and move
or transport the printer.
Do not throw the toner or
toner cartridge into the fire.
Doing so may cause toner
splashes leading to burns.
There are high temperature
parts in the device. Do
not touch the periphery
of the label "Caution High
Temperature", which may
cause burns.
If the toner powder sticks to
your skin like your hands,
wash with soap.
When handling a paper
jam, or replacing the toner
cartridge, make sure not to
get your cloth and hands
dirty. When toner powder
stains on your cloth, wash
with cold water. If you wash
with hot water, the toner
may be soaked into the
cloth; it may be difficult to
clean.
Note
● Use only genuine Oki Data consumable items to ensure optimum quality.
● Service for problems due to use of consumable items other than genuine OKI consumables will incur fees even in the warranty
period or the maintenance contract period.
