METHODS AND APPARATUS FOR ADJUSTING PRINTING DEVICE POWER CONSUMPTION BASED ON USAGE DATA
First Claim
1. A method operable in a system comprising a printing device and a controller for adjusting power consumption of the printing device, the printing device having multiple energy consumption states, the method operable in the controller and comprising:
- acquiring usage data regarding a plurality of print jobs submitted to the printing device over a data collection period of time;
determining a usage profile from the usage data, the usage profile identifying one or more high usage periods of time and one or more low usage periods of time; and
switching the printing device between the multiple energy consumption states when the current time approaches a high usage period of time and when the current time approaches a low usage period of time.

Abstract
Methods and apparatus for adjusting printing device power consumption based on previously acquired usage data. The printing device has multiple energy consumption states including at least a ready state in which the printing device is ready to commence processing of a print job immediately upon receipt and including at least a low power state where the printing device is not ready to commence processing of a newly received print job. Acquired usage data includes parameters of print jobs submitted during a data collection period of time. The parameters may include time and date of submitted print jobs. Based on the usage data a usage profile is determined. The usage profile identifies one or more high usage periods of time and one or more low usage periods of time. Methods and apparatus then switch the printing device among the multiple energy consumption states based on the usage profile.

12. A system for printing, the system comprising:
-
one or more printing engines each having multiple energy consumption states; and a printer controller coupled to the one or more printing engines wherein the printer controller is adapted to determine from previous usage data of the system one or more usage profiles where each user profile corresponds to one of the one or more printing engines, each usage profile identifying one or more high usage periods of time for a corresponding printing engine and identifying one or more low usage periods of time for a corresponding printing engine, and wherein the printer controller is further adapted to switch each printing engine between its multiple energy consumption states based on its corresponding usage profile when the current time approaches a corresponding high usage period of time and when the current time approaches a corresponding low usage period of time. - View Dependent Claims (13, 14, 15, 16, 17)

18. A method operable in a printing system for adjusting power consumption of the printing system, the method comprising:
-
receiving usage data regarding a plurality of print jobs submitted to the printing system over a data collection period of time; determining from the usage data a usage profile, the usage profile identifying one or more high usage periods of time and one or more low usage periods of time; switching, based on the usage profile, the printing system to a ready state prior to an identified high usage period of time such that the printing system is ready to process a new print job upon receipt during the high usage period of time; and switching, based on the usage profile, the printing system to a low power consumption mode during an identified low usage period of time. - View Dependent Claims (19, 20)
