Safety precautions
To use the printer safely
WARNING
There are high voltage electrodes inside the printer. Before you clean the inside of the printer or replace
parts, make sure that you have turned off the power switch and unplugged the printer from the AC power
outlet.
DO NOT handle the plug with wet hands. Doing this might cause an electrical shock.
The fuser unit becomes extremely hot during operation. Wait until it has cooled down sufficiently before
replacing consumable items. DO NOT remove or damage the caution label located on or around the fuser.
