and locks into place.

Pinch the color tab (located on the right side of the envelope cassette) against the post
and move the envelope width to its maximum setting.

Insert the postcards into the envelope tray.
The side of the postcard to be printed should be face down with the top of the
postcard to the right.

might cause binding.
To avoid jams, always set the length and width guides to the correct positions
for your particular postcard.
8
Insert the envelope cassette into the 500-sheet feeder.
Note: To avoid curled postcards, direct the output to the face-up output tray.
