Clearing a paper jam
If the front panel displays this message:
There is probably paper jammed in the printer. Paper jams can have
various causes:
•
The paper is too thick or too thin for the printer, or is otherwise not
supported.
• The paper is creased, misaligned, or bubbled.
• Too much ink is being placed on the paper causing it to cockle or bubble.
• The end of the roll of paper is glued to the core and won’t advance further.
• Pieces of paper or paper powder are clogging up the cutter guide or other moving parts.
See Removing jammed paper for full instructions on how to clear jammed paper.
