paper, the tray is defined for a paper type different than the one you
requested, or the tray is loaded incorrectly. The message identifies the
media size, the media type, the tray that needs paper, and, for custom
size jobs, the dimensions of the required media.
Actions:

    resumes printing on its own.
v  If the tray contains the wrong size paper, load the correct paper size
    into the tray.
v  If the tray is defined for the wrong paper type, use the
    TRAYnTYPE, AUX TYPE, or ENV TYPE item in the Paper Menu to
    specify the right type. See “Defining the Media Size and Type for a
    Tray” on page 47.
v  If the tray contains the correct size and type of paper, make sure the
    paper is loaded correctly. Check the paper guides. The Installed
    Hardware section of the printer configuration page shows what size
    paper the printer paper size sensors have determined is in each
    550-sheet tray. See “Printing the Printer Configuration Page” on
    page 24.

tray specified in the message, you can do the following:
1.   Power off the printer and then power it back on.
2.   Load the correct paper size in the tray you want to use.
3.   Resubmit the job.
