Ozone Filters
Always replace ozone filters as soon as their service life expires (as described in
the service manual).
An excessive amount of ozone can build up around machines that use ozone
filters if they are not replaced at the prescribed time. Excessive ozone could cause
personnel working around the machine to feel unwell.
Power Plug and Power Cord
Before serving the machine (especially when responding to a service call), always
make sure that the power plug has been inserted completely into the power source.
A partially inserted plug could lead to heat generation (due to a power surge
caused by high resistance) and cause a fire or other problems.
Always check the power plug and make sure that it is free of dust and lint. Clean it
if necessary. A dirty plug can generate heat which could cause a fire.
Inspect the length of the power cord for cuts or other damage. Replace the power
cord if necessary. A frayed or otherwise damaged power cord can cause a short
circuit which could lead to a fire or personal injury from electrical shock.
Check the length of the power cord between the machine and power supply. Make
sure the power cord is not coiled or wrapped around any object such as a table leg.
Coiling the power cord can cause excessive heat to build up and could cause a
fire.
Make sure that the area around the power source is free of obstacles so the power
cord can be removed quickly in case of an emergency.
Make sure that the power cord is grounded (earthed) at the power source with the
ground wire on the plug.
Connect the power cord directly into the power source. Never use an extension
cord.
When you disconnect the power plug from the power source, always pull on the
plug, not the cable.
After Installation, Servicing
Disposal of Used Items

Toner or toner cartridges thrown into a fire can ignite or explode and cause serious
