Do not slide the paper into the tray. Load paper as shown in the illustration.
Make sure the guides in the tray or the multipurpose feeder are properly positioned and are not pressing
tightly against the paper or envelopes.
Push the tray ﬁrmly into the printer after loading paper.
If you are loading prepunched paper for use with the staple ﬁnisher, then make sure the holes on the long
edge of the paper are on the right side of the tray. For more information, see the "Loading paper and specialty
media" section of the User's Guide.
Allow the paper to enter the optional mailbox bins properly
Make sure to adjust the bin extender so that the paper size indicators match the size of the paper used.
If the bin extender is shorter than the size of the paper you are printing on, then the paper causes a
jam in the mailbox bin. For example, if you are printing on a legal-size paper and the bin extender is
set to letter-size, then a jam occurs.
