Loading Envelopes in Tray 1
1 Open Tray 1, but do not pull out the
extension. (Envelopes feed best
without the extension.)
2 Open the rear output bin and pull out
the tray extension. (This reduces
envelope curl and wrinkling.)
3 Load up to 10 envelopes in the center
of Tray 1 with the side-to-be-printed
facing up, and the postage-end
toward the printer. Slide the
envelopes into the printer as far as
they will go without forcing them.
4 Adjust the guides to touch the
envelope stack without bending the
envelopes. Make sure the envelopes
fit under the tabs on the guides.
