The printer does not turn on or stay on
When the Pause light does not come on and mechanism 
initialization does not start even when the Power 
 button is 
pressed to turn on the printer, try the following solutions for the 
problem.
❏ Turn off the printer and make sure the power cord is securely 
plugged into the printer.
❏ Make sure your outlet works and is not controlled by a wall 
switch or timer.
❏ Make sure the supplied voltage to the printer matches the 
rating voltage labeled on the printer. If not, turn off the printer 
and unplug the power cord immediately. Contact your dealer 
for assistance. See “Paper Information” on page 299.

Caution:
If the supplied voltage and rating voltage do not match, do not 
plug the printer back in again, as damage may occur.
