This mode is to start-up the printer without using the engine. When the error related to the
engine occurs, you can ignore the error and get the error history or the other counter
information though it is impossible to print. When the printer doesn't work in case that the
connection failure between the main controller and the engine controller occurs, it is
possible to update the main controller itself to recover from the failures.
