Problem Solving

Why does nothing happen when I turn on the printer?
The printer may not be plugged in. Check the power cord connection to the printer and
the outlet.
Why is the ALARM light on?
Check to see if:
Paper is out.
The paper lever is not set for the type of paper that you are using (single sheet or
continuous-form paper).
The paper or ribbon is jammed.
After correcting the alarm condition, you may have to turn the printer off and on again
to make the ALARM light go out.
Why is the MENU light flashing?
The printer suddenly changes to unidirectional printing, then stops completely and the
MENU lamp flashes.
This is a feature designed to protect the printhead. Heat can build up in the printhead
when it has been printing for a long period of time, so when the printhead reaches a
certain temperature, the printer switches to unidirectional printing. If heat continues to
increase, the printer will stop until the printhead cools down; then it resumes printing.
Why does the printer not print when data is sent from the computer?
You may have the printer deselected (the SELECT light is out). Press the SELECT
button. If the SELECT light still does not come on, even though the POWER light is
on, turn the printer OFF and check that the interface connection from the computer is
secure.
