Once you have printed a meter stamp, the postage funds have been “used up” by the machine, even if the printing is illegible. That is why it is important to make sure the correct value is shown on the machine before inserting the mail piece or tape strip, and to not let the ink level get too low. We recommend that you always keep a spare ink cartridge on hand for this reason.
