Embodiments of a method are provided for personalizing a memory card. The method comprises receiving one or more credentials. The method further comprises authenticating the one or more credentials. The method further comprises reserving a memory segment in the memory card based on the authentication, wherein one or more memory segments in the memory card are vacant. The method furthermore comprises writing the one or more credentials on to the memory segment.

Secure authentication using memory cards

A system for accounting for a print job includes a print device having a database, and a server having a database. The print device and the server communicate via a network. The print device and/or the server have means for dynamically updating accounting information for the print job that communicates with the print device and the server via the network. The accounting information resides in the database of the print device and/or the database of the server. A method for accounting for a print job includes providing at least one print device having at least one database and at least one server having at least one database. The method includes communicating between the print devices and the servers via a network for dynamically updating accounting information for the print job stored on the databases of the print devices and/or the databases of the servers.

Integrated adaptable accounting system for a print job

A system updates at least one database and includes at least one slave print device, a master print device having the database or a server having the database, and at least one network accessing mechanism communicating with the slave print device and with master print device or the server via a network for administration of the database. A method is disclosed for updating at least one database. The method includes providing at least one slave print device and a master print device having the database or a server having the database; and at least one network accessing mechanism communicating with the slave print device and with the master print device or the server via a network for administration of the database. The slave print device initiates updating the database of the master print device and/or the server. The slave print device may or may not have a database.

Distributed limit-based accounting for print jobs

A method is provided for a multifunctional printing system in which a plurality of jobs are placed in a queue in anticipation of processing the same. The queue, over time, receives jobs of at least a first user type and a second user type. In operation, first and second jobs of the first user type are placed in the queue. When a third job is ready for placement into the queue, a determination as to whether the third job is of the first user type or the second user type is made. If the third job is of the first user type, then it is processed subsequent to the processing of both the first and second jobs; however, if the third job is of the second user type, then the third job is processed ahead of at least the second job.

Multifunctional printing system with queue management

A method is provided for a multifunctional printing system in which a first job, developed at a first service, and a second job, developed at a second service are placed in a queue for processing. A first value is assigned to the first job and a second value is assigned to the second job, with the first and second values varying in magnitude as a function of the first and second services. In practice, the first job is placed in the queue and a portion thereof is processed. Subsequently, the second job is placed in the queue and processing of the first job is interrupted by the second job if the second value is greater in magnitude than the first value.

A method of locating the position of an object on the platen of a raster input scanner having a movable scan carriage and an extended array of scanners is disclosed. The method includes the steps of obtaining a previously stored theoretical position of the object from a memory, locating the scan carriage at a position spaced a predetermined distance from the previously stored position, moving the scan carriage toward the previously stored position while operating at least some of the scanners until a target on the object is detected by the operating scanners, and storing a target position of the scan carriage where the target is detected. The target position can represent the location of the scanner's calibration strip or the registration position of a document. After the target position is stored, the scan carriage can be located at the target position for calibrating the scanners if the target position represents the location of the calibration strip. Alternatively, the scan carriage can be located at the target position prior to actuating the scanners for each subsequent document to be scanned if the target position represents a document registration position. This procedure is repeated to determine the document registration positions for documents which are placed on the platen manually, by an SADH or SALDH input, by a CFF input, or by an RDH input.

Method of automatically setting document registration and locating

An electrophotographic printing machine in which a controller regulates charging of a photoconductive member in accordance with information stored therein. The controller determines the charging current as a function of the rest time between successive copying cycles.

A photoconductor belt assembly employs a sub-belt having a photoconductive belt secured releasably thereto. The photoconductive belt is advanced from storage and positioned in contact with the sub-belt so as to be readily attached thereto. As the sub-belt advances, the photoconductive belt is positioned thereon in a substantially wrinkle-free condition.

Replenishable photoconductor system

An apparatus in which the lateral alignment of a belt arranged to move in a pre-determined path is controlled. A support mounted resiliently constrains lateral movement of the belt causing the belt to apply a moment to a pivotably mounted steering post. As a result of this moment, the steering post pivots in a direction to restore the belt to the pre-determined path.
