- Use envelopes that weigh from 80 to 95 gsm.
- Some envelope sizes require that you set margins in the application. Make sure you do a test print first before printing many envelopes.
DO NOT use envelopes that:
- Are loosely constructed
- Have windows
- Are embossed (have raised writing on them)
- Have clasps or staples
- Are pre-printed on the inside
- Are self-adhesive
- Have double flaps
You may experience paper feed problems caused by the thickness, size and flap shape of the envelopes you are using.
Before loading envelopes in the tray, press the flaps, edges and corners to make them as flat as possible, as shown in the illustrations.
- If envelopes are "double-feeding," load one envelope in the paper tray at a time.
