serve power when idle for a specific period (by default, five minutes), that is, if no print
jobs are received or buttons are pressed while all covers are closed.
You can specify the period before the printer enters Sleep mode in the Sleep Timer
menu. (See "Menu Settings.")

jobs are received, and the jobs are printed.
