Abstract: A method for reducing a time-to-first-print in an imaging device that includes tracking a set of sleep times between print jobs in an imaging device and determining whether a predetermined number of sleep times in the set of sleep times is reached; and upon a positive determination, identifying a first and a second most recent sleep times stored among the set of sleep times tracked; determining whether each of the first sleep time and the second sleep time is less than a predetermined threshold; and upon a positive determination, determining a value based on an average of the first sleep time and the second sleep time. The value is used as a period of time that the imaging device is powered at a snooze mode prior to transitioning to a sleep mode, and when a print job is received in the imaging device while in the snooze mode, the time-to-first-print from the snooze mode is faster than the time-to-first print when the print job is received while in the sleep mode.

Abstract: A method for associating a customer accessible supply item of a first type with an imaging apparatus includes communicating identification information between the customer accessible supply item of the first type and the imaging apparatus; and operationally locking the customer accessible supply item of the first type with only the imaging apparatus based on the identification information, to the exclusion of other imaging apparatuses and other customer accessible supply items of the first type.

Abstract: A method of storing usage information in an ink jet printer includes storing low priority usage information in a first memory field. First high priority usage information is stored in a second memory field. Second high priority usage information is stored in a third memory field. The second high priority usage information is substantially identical to the first high priority usage information.

Abstract: A method of controlling a temperature of a print chip of a printhead in an ink jet printer includes providing the printer with a memory device. The print chip is provided with and at least one ink-jetting resistor. The printhead is provided with at least one substrate heater and a heatsink attached to the print chip. Power is applied to the substrate heater and/or the ink-jetting resistor. Temperature data associated with the print chip is recorded during the applying step. A thermal resistance value of the print chip to the heatsink and/or a thermal capacitance value associated with the printhead is calculated dependent upon the recorded temperature data. The thermal resistance value of the print chip to the heatsink and/or the thermal capacitance value associated with the printhead are stored in the memory device.
