184 10 - Maintaining and troubleshooting ENWW
• The media stack might exceed the maximum stack height for the tray. Check the label
inside the tray for the maximum stack height. If the media exceeds this level, remove
some of the media from the tray.
• Make sure that the media you are using is not curled. Uncurl the media by gently
bending it in the opposite direction of the curl. If media has been exposed to a humid
environment, it might curl. Media should be stored in a cool, dry place.
z Check the settings
• The media that is loaded in a tray is not the same as the media size or type that is
selected in the printer driver or configured on the control panel. When a media
mismatch exists, the message
Load [type] [size] in tray X appears on the
control-panel display. Load the correct media in the tray and make sure that the media
width and length adjusters fit snugly but gently against the stack.
• The media size or type settings for the tray configured on the control panel do not
match the size or type selected in the printer driver. When a media mismatch exists, the
message
Load [type] [size] in tray X appears on the control-panel display.
Load the correct media in the tray and make sure that the media width and length
adjusters fit snugly but gently against the stack. Check that the media size and type are
set correctly on the control panel.
• To avoid a media mismatch, find out which tray contains the media on which you want
to print, make sure that the media size and type are set correctly on the control panel,
and then select that tray in the printer driver.
z Check the tray
• The media-lift plate inside the tray might be stuck in the lowest position. Pull out the
tray, and then push the tray in again firmly.
• If the media still is not picked up from the tray, open the tray and reposition the media.
Make sure that the media width and length adjusters fit snugly but gently against the
stack. Firmly close the tray.

z Check the output tray
• Make sure that the output tray extension is fully extended.
• The output tray holds up to 100 sheets of plain paper, depending on how much the
media curls and how much ink is used on each page. Remove excess media from the
output tray. You can set the all-in-one to pause when the output tray is full. See
Setting
the automatic paper-type sensor for more information.
