Step Check description Assumed cause Measures Reference
1 Checking the paper path The paper is caught with a
piece of paper, etc.
Remove any paper or foreign
objects on the paper path and
remove the burrs on the parts
such as the guide or the actu-
ator.
2 Checking the guide The guide is dirty. If the guide or the transfer
discharging sheet are dirty
with toner or paper dust, etc.,
clean them with a dry cloth.
3 Checking the guide The guide does not prop-

Check the guide, and remove
any burrs. Also, if the guide
does not operate smoothly
manually, reattach the guide.
Then, replace the guide if it is
not fixed or if there is defor-
mation or frictional wear.
