Abstract: 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.

Abstract: A method of synchronizing the feeding and printing of sheets of media, i.e., paper, envelopes, post cards, etc. even though shingled feeds have occurred in the system. The foregoing is accomplished by utilizing two sensors and counters to monitor two sheets of paper to allow two software tasks to stay in synchronization and release the appropriate print data to the printer even when a sheet of paper was not detected in the feeder appears at the print head. The feeder sensor has a counter for its Lead Edge as does the Start of Print Sensor that is in the system's transport paper path. The feeder sensor counter and the start of print counter are incremented and decremented as the paper approaches the sensor and leaves the sensor. If the lead edge counter of the feeder sensor goes negative, then the feeder has shingled and the data for that sheet of paper must be printed.

Abstract: A mailing machine is provided that, when operating in a differential weighing mode, can detect if a user has replaced one or more mail pieces that may have been inadvertently removed at the same time back onto the scale. If the mailing machine detects such replacement within a predetermined time period after the scale has stabilized, the weight calculated for the mail piece can be reduced by the amount added back to the scale, or, alternatively, the user could be requested to confirm that multiple pieces were inadvertently removed from the scale at the same time, the user is trying to correct that error, and a new weight is to be determined.

Abstract: Various methods for detecting the removal of a processing unit, such as a microprocessor or a microcontroller, form a printed circuit board in a secure printing system, such as a postage metering system are provided. The methods utilize one or more of a real time clock provided internal to the processing unit, a CMOS device provided on the printed circuit board external to the processing unit, and CMOS memory internal to the processing unit to detect the removal of the processing unit and therefore an attack.

Abstract: An apparatus includes a printer and a buffer coupled to the printer for temporarily storing sheets fed out from the printer. The apparatus further includes a control mechanism for monitoring the buffer to determine a number of sheets currently stored in the buffer. The apparatus also includes a data source device that is separate from the printer and is coupled to the printer for selectively providing pages of print data to the printer. The data source device is coupled to the control mechanism and is operative to provide the pages of print data to the printer in response to control signals from the control mechanism.

Abstract: A system and method for efficient uncorrectable error detection in flash memory is described. A microcontroller including a non-volatile flash memory utilizes an Error Correction Code (ECC) having a certain error detection and correction bit strength. The user data is first processed by a hash function and hash data is stored with the user data. Then, the user data and hash data are processed by the ECC system. In detection, the hash ensures that a relatively low bit-strength ECC system did not incorrectly manipulate the user data. Such a hash integrity check provides an efficient, robust detection of incorrectly corrected user data resulting from errors beyond the correction but strength of the ECC system utilized.

Abstract: In a value dispensing system, a system and method for securely loading and executing software in a secure device that does not include any non-volatile programmable memory is provided. A non-secure portion of the value dispensing system stores software for loading into the secure portion when needed. Commands being sent to the secure printer are monitored to determine if the secure has the necessary software to execute the command. If the secure device currently does not have the necessary software to execute the command, the command is delayed and the proper software is loaded from the non-secure portion to the RAM of the secure device. A signature associated with the software is verified to ensure the authenticity of the software. If the signature is verified, the command is passed to the secure device, and, utilizing the software in the RAM, the command is executed by the secure device.

Abstract: The present invention relates to a method of converting data stored in one or mores files from a first format to a second format. The files include one or more records, with each record including one or more fields of data. Each of the records is associated with a first data map corresponding to the first format and a second data map corresponding to the second format. The method converts each file, record by record, using the information from the first and second data maps associated with the selected record. A determination is made as to whether each field is present in the second format, and if so, the field data is copied to a new record at a field location for the field that is set forth in the second data map.

Abstract: A method and system that allows for large amounts of data to be printed utilizing a small memory is provided. The complete image to be printed on the print medium is separated into different regions each having associated print data. The memory device, while being too small to store all of the print data for the full image, is capable of storing the print data associated with each region. The print data for each region is released from the print head controller to the memory device for printing in a timed fashion based on movement of the print medium. The print data for a subsequent region will not be passed to the memory until the print medium has moved a sufficient distance, thereby indicating that printing of the preceding region has been completed.

Abstract: A mailing machine is provided that determines if entry into a disabled state is coupled with the need for auxiliary information to be entered by the user. If auxiliary information is required to be entered by the user, the print head will not move to the capped position but instead remains in the printing position, and a timer is activated to provide the user with time to enter the information. If the user enters the required information before a predetermined amount of time has expired, the mail piece will be processed without any delay required for the print head to move from the capped position to the printing position. Only if the user has not entered the required information within the predetermined amount of time will the print head move to the capped position.

If the mailing machine detects such replacement within a predetermined time period after the scale has stabilized, the weight calculated for the mail piece can be reduced by the amount added back to the scale, or alternatively the user could be requested to confirm that multiple pieces were inadvertently removed from the scale at the same time and the user is trying to correct that error and a new weight determined.

Abstract: Methods and systems are provided that reduce feeding and weighing errors in a manually fed mailing machine thereby allowing a very fast throughput to be achieved while a user is taking mail pieces off of a scale and feeding them into the mailing machine. Weights or postage amounts for additional subsequent mail pieces are accepted before the processing of a preceding mail piece has been completed. A queue is maintained for information that has been provided by an attached scale such that the mailing machine can correctly associate each weight or postage amount with the appropriate mail piece when it is fed into the mailing machine. When processing of a previous mail piece has been completed, the information from the next location in the queue is obtained and utilized to generate an indicium for the next mail piece fed into the mailing machine.

Abstract: A system and method to remotely enable and disable features in a mailing system is provided. When a customer desires to change the operating features of a mailing system, the customer places an order with a data center. The data center generates a file that identifies each of the features that should be enabled within the mailing system, and the file is sent to the mailing system, along with any files required to implement and support the enabled features, via a network. The mailing system will store the required files, and purge any files no longer required to implement and support features that are no longer enabled. The enabling and disabling of operating features is thus performed remotely from the data center, and does not require a customer service representative to physically visit the location at which the mailing system is installed.
