摘要:
A replaceable unit monitor reader system includes a host processor and a coupler board. The coupler board had a detection circuitry that provides an auto-detect, auto-initiate and/or auto-select ability. After receiving command from the host processor, the coupler board enables communication with a CRUM without requiring a further command from the host processor.

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.

Control of a module involves providing the module with an electronic tag comprising a tag memory and a tag communication element. After the tag is associated with the module, a tag reader electronically reads identification information from the tag and verifies that the module identification information matches predetermined identification criteria. If the identification information matches, a tag writer programs the tag with configuration information. The configuration information places the module into a predetermined module configuration.

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. By expanding this intelligent on-board monitoring system with expanded memory, either on board the replaceable module, or by way of network access, the capability to enable software upgrades is provided. The software upgrades may relate to the performance of the replaceable module or to the machine into which it is installed. These software upgrades may be accomplished without requiring computational resources of the printing apparatus itself and by proper scheduling without impacting customer machine utilization.
摘要:
By providing a secure EEPROM (Electrically Erasable Programmable Read Only Memory) device or other non-volatile memory (NVM) with a wireless interface as a system operation key (SOK) to control the configurable machine option attributes, various problems associated with machine option configuration and updates may be accommodated. At initial SOK install the identity of the machine is written to the NVM, i.e. the machine serial number. This is performed during the initial machine power up or reboot sequence. As part of the power on or reboot routine the machine will check via the wireless interface to ensure no tampering has taken place and that the machine identity and the NVM serial number location data match. A new swapped in SOK can be installed so long as the NVM serial number location has not been previously written to with a conflicting identification number. The machine will then write the serial number to the new SOK thereby protecting it.
