CAUTION
There are some areas inside the machine and cartridge which are subject to 
high voltages and high temperatures. Take adequate precaution when 
performing internal inspections to avoid burns or electrical shock.
NOTE
When removing jammed paper from inside the machine, take care not to allow the toner 
on the jammed paper to come into contact with your hands or clothing. If they become 
dirty, wash them immediately with cold water. Washing with warm water will set the toner, 
and make it impossible to remove the toner stains.
