Try another envelope brandif you do not get desired results.• Maintain constant temperatures and relative humidity.• Store unused envelopes in their packaging to avoid excess moisture and dryness which can affectprint quality and cause wrinkling. Excessive moisture can cause the envelopes to seal before orduring printing.• Remove air bubbles from the envelopes before loading them into the tray by setting a heavy bookon top of them.• In the print driver software, select Envelope as the paper type.• Do not use padded envelopes. Use envelopes that lie flat on a surface.• Do not use envelopes with heat activated glue.• Do not use envelopes with press and seal flaps.• Use only paper envelopes.• Do not use envelopes with windows or metal clasps.
