US Classification:

219543, 219552, 338307

Abstract:

A method and apparatus for heating a charging unit to an appropriate temperature in a uniform manner is provided. In accordance with one example embodiment of the present invention, a heater for use in a charger includes a base. First and second contacts are disposed on the base. A heating element couples the first contact and the second contact. The heating element has an energy density that increases approximately exponentially from a first energy density at locations distal from the first and second heat sink locations to a relatively higher second energy density at locations proximal to the first and second heat sink locations. The heater, according to further embodiments of the present invention, is disposed on an opposite side of the substrate layer from the AC electrode layer, and underneath the charger.

International Classification:

G03G015/00

US Classification:

399 12

Abstract:

In a printing apparatus, verification of the correctness of a particular replaceable module takes place before an operating element of the printing apparatus fully engages the replaceable module. A printing apparatus coupler establishes a communication link with a tag on the replaceable module as the replaceable module is being inserted into the printing apparatus. The printing apparatus coupler receives module identifying information from the tag. The coupler determines from the identifying information whether the replaceable module is appropriate for that location in that printing apparatus, and performs either an acceptance action to accept the replaceable module, or a rejection action to reject the module.

US Classification:

713340, 702 17, 702 62, 713330, 713300

Abstract:

A hardware interface usable to communicate with electrically erasable read-only memory devices and, optionally, other external controls or devices, includes self-monitoring power supply circuitry, an EEPROM driver and noise and signal degradation prevention circuitry, and optional input/output circuitry which provides for programmatically cycling power to the memory device. The self-monitoring power supply circuitry is capable of determining whether a power supply has reached the hardware interface. The EEPROM driver and noise and signal degradation prevention circuitry reduces signal noise and/or signal degradation and driver circuitry for programming, monitoring, and downloading information to and from the EEPROM devices. The digital input/output circuitry is capable of controlling the power supply to the hardware interface, downloading or monitoring information to the hardware interface, or controlling/responding to external devices or controls.

International Classification:

G03G015/00

US Classification:

399 24

Abstract:

An intelligent on-board monitoring system for replaceable module for a printing apparatus includes a memory element, an input for receiving information either from sensors on the replaceable module, or from the printing apparatus concerning printing operations performed, and a microprocessor connected to the memory for performing calculations upon data stored in the memory and upon the input information. The calculations produce results related to the performance of the replaceable module. These results can either be communicated to the printing apparatus, or used to control an adjustable operating parameter of the replaceable module itself, all without requiring computational resources of the printing apparatus itself.

Abstract:

A portable programming device for electronically programming an electronic tag associated with a module includes a hand-held data receiver containing a communication element adapted to receive data from an electronic tag associated with a module and a data processor having programmed processing instructions. The data processor analyzes data received at the communication element in accordance with programmed processing instructions to produce a processor result based on the received data. The portable programming device also includes a hand-held tag writer comprising a communication element for writing tag content information to a tag memory segment of the electronic tag in response to the processor result.

Abstract:

Determining an end-of-life prediction of a replaceable cartridge may be accomplished by analyzing input parameters independent of the cartridge, in addition to parameters of the cartridge. An event count denoting a consumption event is read from a memory in the replaceable cartridge. A current consumption status of the replaceable cartridge is determined based on an initial load and the event count of the replaceable cartridge. An input parameter is received from an input device regarding a next pending process that involves a pending consumption increment of the replaceable cartridge. A subsequent consumption status of the replaceable cartridge is determined corresponding to the current consumption status altered by the pending consumption increment. The subsequent consumption status is compared to a replacement condition to decide whether a replacement condition is satisfied. An alert indicator is signaled to an operator upon satisfaction of the replacement condition.
