HOT!  When you open the front or rear cover of the printer, never touch the shaded
parts shown in the following diagram.
Clear the jammed paper referring to the following description.
If the jammed paper is removed completely by using the information in the
following steps, you can install the paper cassette first, and 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

✏ Note
y  If a paper jam occurs when using the lower tray unit, check for correct
installation of the upper paper cassette.
y  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.
1. Pull the paper cassette completely out of
the printer.
2. Pull the jammed paper up and out of the
printer.
3. Open the front cover.

To prevent damage to the printer caused by static electricity, do not touch the
electrodes shown in the illustration.
