Situation
Solution
General repeated jam problems
1. Verify that the media is correctly loaded in the trays and that
all width guides are correctly set (see
Print tasks
on page
97).
2. Verify that the paper tray is set for the size of media installed
and that the tray is not overloaded.
3. Try turning over the stack of media in the tray. If you are
using prepunched or letterhead paper, try printing from tray 1.
4. Do not use previously printed media or torn, worn, or
irregular media. For recommended media for your MFP, see
Supported paper and print media sizes
on page
81.
5. Check the media specifications. (See
Supported paper and
print media sizes
on page

recommended specifications, problems can occur.

the MFP

7. Check that all damaged or jammed media is removed from
