Tips for avoiding jams
If media repeatedly jams in the all-in-one, follow these tips to avoid the jams.
z Make sure that the printhead latch is correctly engaged.
z Make sure that nothing is blocking the paper path.
z Do not overload the trays. Tray 1 holds up to 150 sheets of paper and tray 2 holds up to
250 sheets. Make sure that the media does not exceed the maximum stack height that is
indicated inside the tray.
z Load media correctly. See Loading the print media for more information.
z Make sure that the media width and length adjusters fit snugly but gently against the stack
of media, but do not wrinkle or bend the media.
z Do not combine different media types and sizes in the same tray.
z Always use media that meets specifications. See Choosing the print media for more
information.
z Do not use media that is damaged, curled, crumpled, or wrinkled. Do not use media with
cutouts or perforations or media that is heavily textured or embossed.
z Avoid media that is too thin, has a slick texture, or “stretches” easily. Such media does not
feed correctly through the all-in-one.
z Do not add media to a tray while the all-in-one is printing or scanning.
