When you specify 1 minute for Sleep, the printer enters power saver mode 1 minute after it finishes a job. This uses much less energy, but requires more warm-up time for the printer. Specify 1 minute if your printer shares an electrical circuit with room lighting and you notice lights flickering. Select a high value if your printer is in constant use. In most circumstances, this keeps the printer ready to operate with minimum warm-up time. Select a value between 1 and 60 minutes for power saver mode if you want a balance between energy consumption and a shorter warm-up period. The printer automatically returns to the standby mode from the power saver mode when it receives data from the computer or remote fax machine. You can also change the status of the printer to the standby mode by pressing any button on the operator panel. Date & Time Purpose: To specify the date and time formats.
