SYMPTOM
Only one self-test ticket can be done. When you press the print button again, only
blank tickets are produced.
ACTION
Check the setting of parameter n7, "Clear memory after print". If it is ON,
this is the correct behavior.

when the black line at the end of the self-test ticket is printed.
