The message "Mailpiece too long" appears when feeding mail.


The franking machine detects a sensor fault.


  1. Remove the power lead from the rear of the franking machine.
  2. Use a compressed air duster to spray along the mail path. This clears away any dust or debris that has built up over time. Order a cleaning kit from Pitney Bowes.
  3. Wait 30 seconds.
  4. Replace the power lead.
  5. Wait for the franking machine to initialise.
