DISPLAYING POWER-ON INSTRUCTIONS DURING POWER-SAVING MODE USING BISTABLE DISPLAY

摘要

Methods and systems monitor the activity usage level of a printing apparatus and place the printing apparatus into a power saving mode based on the activity usage level. Such methods and systems sense whether the power supply is to be disconnected from the graphic user interface based on the printing device going into the power saving mode. The graphical user interface comprises a bistable display that continues to show a most recently provided screenshot after the power supply is disconnected. Such methods and systems cause the graphic user interface to display power saving mode information of the printing apparatus (instructions for a user to take to have the printing apparatus leave power saving mode) immediately prior to the power supply being disconnected from the graphic user interface, such that the graphic user interface continues to display the power saving mode information after being disconnected from the power supply.
