Abstract
Mailing machine comprising a printer module including an array of ink jet print elements for printing on an envelope having a top surface, a registration shield located below and spaced apart from the printer module and a transport apparatus. The registration shield includes a top surface and a bottom surface and has an opening through which the array of ink jet print elements project ink onto the top surface of the envelope. The transport apparatus feeds the envelope in a path of travel so that the envelope passes between the registration shield and the printer module. Additionally, the transport apparatus includes a device for biasing the top surface of the envelope into contact with the registration shield. The registration shield further includes a channel extending parallel to the path of travel and in substantial alignment with the opening so that the top surface of the envelope in proximity to the channel does not contact the bottom surface of the registration shield so as to allow air to flow through the opening.
