Runtime diagnostics (sometimes called level 2 diagnostics) run during normal printer operation. When the following
conditions occur, the printer automatically turns off the appropriate motors and disables printing to prevent damage to the
printer:
Paper out
Receipt cover open
Knife unable to home
Printhead too hot
Voltages out of range
The LED on the operator panel will signal when these conditions occur as well as indicate what state or mode the printer is
in.
Remote diagnostics
Remote diagnostics (sometimes called level 3 diagnostics) keeps track of the following tallies and prints them on the
receipt during the print test. See the sample test printout on the next page. These tallies can be used to determine the
printer’s state of health.
