A system architecture is provided for a fixed-head mailpiece printer. The printer includes at least two laterally and longitudinally-spaced print heads for depositing ink on a face surface of a mailpiece. The print system architecture includes print application software or software program code operative to render print image data into a plurality of logical rectangular bitmap print buffers. Further, a field programmable gate array (FPGA) remaps each of the logical rectangular bitmap print buffers into one of the print heads based upon its spatial position relative to the mailpiece. Furthermore, the FPGA is operative to control the deposition of ink from the print heads based upon the print image data contained in the print buffers. Moreover, the FPGA minimizes processing time associated with print image rendering to achieve enhanced print system throughput.

A high speed mailing system that utilizes a single postal security (PSD) device in conjunction with multiple printing modules is provided. The control unit with which the PSD is associated is coupled to each of the printing modules through a multiplexer capable of switching between each of the printing modules. During initialization of the system for each mail processing session, the control unit establishes a secure communication session with each printing module individually through the multiplexer. Thus, the control unit can generate and provide indicia that can be printed only on the specific printing module that is currently in use. The multiplexer can switch between printing modules during operation of the mailing system, thereby always keeping one printing module in use while allowing the printing module that is not currently being used to perform any necessary maintenance operations, without having to stop the processing of mail pieces.

A method and device for locking and unlocking a print head assembly along a shaft in an addressing machine. The print head assembly is fixedly mounted on a locking mechanism, which comprises a cylindrical body slideably mounted on the shaft and a cam ring rotatably mounted over the cylindrical body. The cylindrical body has a slot for seating an elongated spline. When the locking mechanism is operated in a locking position, the inner circumference of the cam ring presses the spline against the shaft, preventing the cylindrical body from moving along the shaft. The cam ring has a relief on its inner circumference such that, when the cam ring is rotated to the unlocked position, the spline is partially seated in the relief, thereby reducing the pressure exerted by the spline against the shaft. As such, the position of the print head assembly can be adjusted.

In a mailing machine including an impression roller, a postage indicia printing drum overhanging the impression roller, and apparatus for rotating the impression roller and drum in timed relationship with one another for feeding a sheet beneath the drum and in printing engagement therewith, wherein the feeding apparatus includes shaft structure on which the impression roller is mounted for rotation therewith, there is provided an improved impression roller. The impression roller comprises: two annularly-shaped inner members made of a soft resilient material, the inner members coaxially mounted side by side on the shaft structure; two annularly-shaped outer member made of a hard resilient material, the outer members coaxially mounted on the inner members; and four annularly-shaped disc members made of a hard resilient material, the disc members coaxially mounted on the shaft structure, each of the disc members dimensioned such that the width thereof is half the width of an outer member, and each of the disc members including a plurality of apertures formed therethrough at equidistantly spaced intervals along a circular line extending coaxially thereof. Preferably, each of the disc members is not more than substantially one-eighth of an inch in width.

An apparatus for free-spraying an inkjet printhead includes a feed table with a slot carrier which can be deflected counter to a spring force and has at least one free-spraying slot disposed opposite at least one inkjet printhead. The slot carrier is shaped in such a way that the at least one free-spraying slot is deflected out of a transport path corresponding to an entry of an item of mail being fed in.

In a postage meter machine that has a printing unit with a replaceable print head, a print head for such a postage meter machine and a method for the authentication of such a print head, a number of manipulation possibilities are precluded, such as refilling an authorized print head, unauthorized ink usage of a printhead and using an authorized print head in a conventional printer without paying fees for franking. For this purpose a security code is generated by an encryption algorithm from a first identification code attached to the print head and from a second identification code stored in a memory unit allocated to the print head, and is compared to a security code that is likewise stored in the memory unit when the print head is manufactured.

In a digital postage meter having a housing shell, a display screen mounted in the housing shell, and a removable printhead, a method of transmitting information from the printhead module to the display screen. The method includes: storing the information in a memory device in the printhead module; retrieving the information in a first communication device in the printhead module; transmitting the information from the first communication device to a second communication device external to the printhead module, wherein the second communication device interprets the information; and transmitting the interpreted information to the display screen.

A postage meter has a removable franking head and a stationary base on which said head is mounted at a defined location, with locking means coupled to an external control for locking the head in place on the base. The meter also has two complementary connector portions for electrically interconnecting the head and the base by one of said connector portions plugging into the other. One of said first and second connector portions is movably mounted to move between an unplugged first position and a plugged second position in which the connector portions are plugged together, and is connected to actuator means for ensuring that the connector portion is in said unplugged first position while said head is being installed on the base.
