1. Close the roll paper cover.
2. While pressing the Feed button on the control panel, turn on the printer. (Keep pressing the
Feed button until the printer starts printing.) 
The printer prints out the various printer states.
3. When all printer states have been printed, make sure that the following message is displayed and
the Paper LED flashes.
"If you want to continue SELF-TEST printing, please press Feed button."
The printer is now in the self test wait mode.
4. To start a test print, press the Feed button when the printer is in the self test wait mode.
5. Check that the following has been printed.
"*** completed ***"
This indicates that the printer has been initialized and made the transition to the normal mode.
