User Guide

If the printer has not been turned on before, or a new EEPROM has been installed, the default values
for the printer functions will be loaded into the EEPROM during startup.
Runtime Diagnostics
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
● Rear cover open
● Knife unable to home
●

The LED on the operator panel will signal when these conditions occur as well as indicate printer
state or mode.
