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.

System and method for reducing power consumption in a device

A method for purging an ink jet print head to clear ink jet orifices is provided. A purge cap forms a vacuum seal over the orifice plate of the print head. Multiple low pressure differential vacuum pulses are applied to the purge cap to remove debris and trapped air bubbles from the ink jet orifices. The low pressure pulses avoid cavitation inside the print head and reduce the amount of ink expelled during the purging process.
