The Print on Envelopes screen says, "Not Ready to Print" and will not print.


Several things can cause "Not Ready to Print":

  • The jam release may be open.
  • The ink tank may be missing or empty.
  • The printhead may be missing.
  • You may need to select an account.
  • You may need to upload transactions.
