If it is not possible to print postage directly onto your envelope, you can print it onto a tape. You can then apply the tape to the envelope.
Push the tape lever to the right and hold it there (a). Drop a stack of strip tapes down into the slot (b). Make sure that the printable side faces to the right (toward the touchscreen).
- On the Home screen, tap Print on Envelopes.
- Select the postage mode and conditions (account, class and special service, weight).
- For a single tape, tap the Tape button. The default value is set to 1 tape.
- For multiple tapes, tap the number on the tape button and use the keypad to enter the number of tapes.
