A method for identifying an installed cartridge in a cartridge carrier of an imaging apparatus, wherein the imaging apparatus communicates with the installed cartridge over at least one line, includes sending an ID command to the installed cartridge via an ID line; and monitoring the ID line for an affirmative response from the installed cartridge, wherein the affirmative response over the ID line indicates that the installed cartridge is a perforator cartridge.

Method for identifying an installed cartridge

A method for providing technical support to a customer relating to an imaging cartridge used in an imaging apparatus includes receiving a request from the customer for assistance relating to the imaging cartridge; executing diagnostic software associated with a type of the imaging apparatus based on the request to generate a diagnostic code pertaining to the imaging cartridge; receiving the diagnostic code from the customer; performing an analysis of the diagnostic code; and determining an action to be taken based on the analysis of the diagnostic code.

Method and system for providing technical support relating to an imaging cartridge

A printhead temperature monitoring system includes a processor having a top priority interrupt input, a normal priority interrupt input, and at least one input for receiving temperature related signals. The processor is programmed or otherwise operable to calculate a printhead temperature based at least in part upon temperature related signals read on the input. A single timer circuit provides interrupt signals to the interrupt inputs of the processor. An interrupt control circuit is connected between the single timer circuit and the processor for selectively controlling application of timer circuit interrupt signals to the top priority interrupt of the processor and the normal priority interrupt of the processor.
