The machine disables paper feed from a tray if the paper size cannot be detected (if the
paper size actuator is broken or no tray is installed).
For non-standard paper sizes, if they are not visible on the user tool screen for selecting
paper sizes, then set SP 5112 to "1". If the user selects one of these sizes, auto paper size
selection is disabled.
