Maintenance And Inspections - Canon Laser Shot LBP5970 User Manual

The laser beam can be harmful to human bodies. Since radiation emitted inside the
•
printer is completely confined within protective housings and external covers, the
laser beam cannot escape from the printer during any phase of user operation. Read
the following remarks and instructions for safety.
- Never open covers other than those instructed in this manual.
- Do not remove the caution label attached to the cover of the laser scanner unit.
- If the laser beam escapes from the printer, exposure may cause serious damage to
your eyes.

Maintenance and Inspections

WARNING
When cleaning the printer, turn OFF the printer and computer, remove the USB cable,
•
and then unplug the power plug. Failure to observe these steps may result in a fire or
electrical shock.
Unplug the power plug from the AC power outlet regularly, and clean the area around
•
the base of the power plug's metal pins and the AC power outlet with a dry cloth to
ensure that all dust and grime is removed. If the power plug is plugged for a long
period of time in a damp, dusty, or smoky location, dust can build up around the
power plug and become damp. This may cause a short circuit and result in a fire.
Clean the printer using a slightly dampened cloth with water or a mild detergent
•
diluted with water. Do not use alcohol, benzene, paint thinner, or other flammable
substances. If flammable substances come into contact with electrical parts inside
the printer, it may result in a fire or electrical shock.
There are some areas inside the printer which are subject to high-voltages. When
•
removing jammed paper or when inspecting the inside of the printer, do not allow
necklaces, bracelets, or other metal objects to touch the inside of the printer, as this
may result in burns or electrical shock.
Do not throw a used drum cartridge, toner cartridge, or waste toner container into
•
open flames, as this may cause the toner remaining inside the cartridge to ignite,
resulting in burns or a fire.
