5.   Adjust the size guide on the right side of the auxiliary tray to the postcard size. Make sure you place the top edge of the postcards under the retaining clip at the
right side of the auxiliary tray. 6.   Use your print application or the Paper Menu to set AUXSIZE to match the postcard size you loaded in the auxiliary tray (see “Defining the Auxiliary Tray
Paper Size” on page  47).   Values specified in print jobs override values you set at
the printer. If you want to feed the postcards manually into the auxiliary tray, use your print
application or the Paper Menu to set MANUAL to ON (see “Paper Menu” on
page  57). Note:   PostScript jobs can override MANUAL=OFF; however, they cannot override
MANUAL=ON.   Therefore, if you do set MANUAL to ON, make sure you reset
MANUAL to OFF after you complete the jobs you want to print manually. 7.   To close the auxiliary tray, see Step 7 on page  30. Chapter 3.   Paper Handling 37
