Paper Jams
The   (Paper Jam) indicator (orange) blinks, and the following messages appear 
in the Printer Status Window when a paper jam occurs during printing.
WARNING
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.
CAUTION
•The fixing unit and its surroundings inside the printer are hot during use. Make 
sure the fixing unit is completely cool before removing the jammed paper. 
Touching the fixing unit when it is still hot may result in burns.
•When removing jammed paper, take care not to allow the toner to come into 
contact with your hands or clothing, as this will dirty 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.
•When removing paper jammed inside the printer, remove the jammed paper 
gently to prevent the toner on the paper from scattering and getting into your 
eyes or mouth. If the toner gets into your eyes or mouth, wash them 
immediately with cold water and immediately consult a physician.
•When removing jammed paper, take care not to cut your hands with the edges 
of the paper.

Paper Jams •
Keep your hands or clothing away from the roller in the output area after 
removing jammed paper completely. Even if the printer is not printing, sudden 
rotation of the roller may catch your hands or clothing, resulting in personal 
injury.
IMPORTANT
•Remove jammed paper while the power of the printer is ON. If the power is turned OFF, 
the data being printed will be deleted.
•Applying excess force may result in tearing paper or damaging the parts in the printer. 
When removing jammed paper, pull out the paper in the most appropriate direction, 
judging from the position of the paper.
•If paper is torn, be sure to find and remove any remaining pieces of paper.
•The error message may remain if jammed paper is removed without opening the front 
cover. In this case, open and close the front cover once.
•Do not touch the high-voltage contact (A) or the electrical contact (B) shown in the figure, 
as this may result in damage to the printer.
•Do not touch the transfer roller (C), as this may result in deterioration in print quality.
