Following removal of the paper, return the transparent plastic covers to

Close the printer's front cover. This completes the actions for clearing
paper jamming.
Notes • Sometimes the page on which the paper jam occurred will not be
re-printed depending on the location of the paper jam.
• Note that your hands may become dirty from unfused toner when
removing paper jams.
Frequent occurrence of paper jams may indicate you are using a paper specification
which does not suit the printer. If this appears to be the case, please change to a
different type of paper.
If you have tried changing paper types and paper jams still occur frequently, there
may be a problem with the printer. In this case, please contact your Kyocera
dealer.
Open the second cover
