1. A process for controlling power consumption levels in a device comprising:
- operating a device at a fully operational power level;
counting a first wait time;
modifying a first wait time modifier in response to detection of device use prior to expiration of the first wait time; and
reducing power consumption from the fully operational level to a low power level in response to expiration of the first wait time.

Abstract
A system and process enable a device to adjust the duration of various power modes based on usage of the device. The process includes operating a device at a fully operational power level, counting a first wait time, modifying a first wait time modifier in response to detection of image generating device use prior to expiration of the first wait time, and reducing power consumption from the fully operational level to a low power level in response to expiration of the first wait time.

8. A system for adjusting power consumption levels in a device comprising:
-
a timer for generating a power level adjustment signal in response to expiration of a time period being counted by the timer; a timer modifier for modifying the time period being counted by the timer; a device controller for controlling operation of a device, the device controller modifying the timer modifier in response to the device controller detecting usage of the device; and a power controller for selectively setting the device at one of a plurality of power consumption levels in response to the power level adjustment signal. - View Dependent Claims (9, 10, 11, 12, 13)

14. An ink jetting printer comprising:
-
an ink reservoir for storing liquid ink; a print head for receiving the liquid ink from the ink reservoir; an imaging member for receiving liquid ink ejected from the print head to form an ink image on the imaging member; a transfer subsystem for fixing the ink image, the transfer subsystem including at least one heated roller; and an electronics module for controlling operation of the ink jetting printer, the electronics module further comprising; a timer for counting time periods and generating a power adjustment signal upon expiration of a time period counted by the timer; a timer modifier for modifying the time period being counted by the timer; a printer controller for generating control signals for operation of the printer and for modifying the timer modifier in accordance with usage of the printer; and a power controller for setting a power consumption level to one of a plurality of power consumption levels for the printer in response to receipt of one of a power adjustment signal and an imaging generating request. - View Dependent Claims (15, 16, 17, 18, 19, 20)
