"Envelope not detected" message on the DM50-DM60 Series

Print this support article
Products affected: DM50™, DM55™ (K721), DM60™ (K722)

Issue

Your franking machine displays the message Envelope not detected and will not print.

Cause

This message can appear because you have not fed the envelope far enough to the rear and the right of your franking machine. It can also be caused by jammed material such as paper or alternatively it can be caused by a sensor issue.

Resolution

  1. Ensure you feed the mailpiece against the rear wall of your franking machine and then fully over to the right. This allows the sensor to detect the mailpiece.
  2. Power down the franking machine by removing the power lead from the back.
  3. Once the display has gone off, open the cover.
  4. If the meter is a new installation, ensure that any packing and shipping tape has been removed from inside the franking machine. The shipping tape is a strip of yellow or blue tape.
  5. Check for any obstructions in the franking machine (jammed paper or a label, paperclip, etc).
