4 Pull out the MP tray support flap.
If envelopes are creased after they have been printed:
At the back of the DCP, open the back output tray and push down the blue tabs at the left and right hand sides (as shown in the figure below). When you have finished printing your envelopes, close the back output tray to reset the two blue tabs back to their original position.
5 Put the envelopes in the MP tray so that they touch the back of the tray. Do not put more than 3 envelopes in the MP tray at any one time, or it may cause a jam.
Make sure that the envelopes are neatly stacked and in the proper position in the MP tray. If they are not, the envelopes may not be fed properly, resulting in a skewed printout or a jam.
