Runtime Diagnostics

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
● Printhead too hot
● Voltages out of range
The LED on the operator panel will signal when these conditions occur as well as indicate printer
state or mode.
