and put it back into the paper cassette.
· Reduce the amount of paper in the paper cassette, then try again.
· Check that manual feed mode is not selected in the printer
driver.

application software must be set up correctly to print on the
envelope size you are using.  This is usually done in the page
setup or document setup menu of your software.  Refer to your
software application manual.

Clear the jammed paper referring to the following description or you can view the
paper jam instructional video on the CD-ROM.
If the jammed paper is removed completely by using the information in the
following steps, you can close the paper cassette first, then close the front cover and
the printer will resume printing automatically.  If the printer does not resume
printing automatically, press the control panel button.  If the printer still does not
resume printing, please check that all the remaining jammed paper has been
removed from the printer.  Then try printing again.
2Note
· If a paper jam occurs when using the lower tray unit, check for correct
installation of the upper paper cassette.
· Always remove all paper from the paper cassette and straighten the stack when
new paper is added.  This helps prevent multiple sheets of paper from feeding
through the printer at one time and reduces paper jams.
