When removing the jammed paper, do not touch the transfer roller
(shaded part) as its surface is very delicate and susceptible to finger oil
and scratches, which may lead to print deterioration.
Be careful when removing the paper; toner on the paper might get onto
your hands or clothing. If this happens, wash it off immediately with cold
running water.
To avoid possible damage to the printer, do not touch the pins near the left
end of the transfer roller.
