2.2 Switching On/Off the Power
Switching On the Power
1. Press the power switch to the <|> position.
2. When the power is switched on, the display 
reads [Please wait...]. Wait until the 
message changes to [Ready to print].
Note
• When the display reads [Please wait...], the printer is 
warming up and is not ready to print yet.
• If an error message is displayed, refer to "Error 
Messages (in Alphabetical Order)" (P. 148) to remedy 
the error.
Switching Off the Power
Important
• The <Power Saver> lamp blinks when the hard disk is being accessed when the printer is in the Power 
Saver mode. Do not switch the power off when the <Power Saver> lamp is blinking.
• Do not switch the power off when the display reads [Please wait...].
• Do not switch the power off during printing. Doing so can cause paper jams. 
• Switching the power off erases the print data remained in the printer and the information stored in the 
printer's memory.
1. Make sure that printer is not in operation by 
checking the display or indicator lamps.
2. Press the power switch to the <O> position.
