Numeric keypad commands The numeric keypad is used to specify numeric values. The numeric keypad provides a shortcut key to items in the menus if the device is in an idle state. Pressing the numbers that correspond with the position of the menu item opens that menu. For example, to print a configuration page, the customer can press 22. The first 2 represents the Information menu, which is the second menu. The second 2 represents the Print configuration page command, which is the second item in the Informationmenu list. The menus change dynamically. The Configure device menu has flexible menus that can be used to configure accessories depending on what accessories are available, so the number sequence might not be the same for all devices. Pressing a number should correspond to the same sequence that is used when navigating to that item in the list and pressing . The exception to this approach is when the display contains a list of values. In this case, typing the number moves to that item in the list but does not select the item. This is the same for continuous values that can be specified by using the numeric keypad. For example, to specify the number of copies, the customer presses the appropriate number and then presses . The following table outlines what happens in certain printer states when a button on the numeric keypad is pressed. Table 12.
