5.5 Adjusting the Automatic Ribbon Saver
The ribbon saver reduces the consumption of transfer ribbon by lifting the printhead while feeding blank label areas.
The printhead will be lifted by eccentrics and the ribbon unwinder will be blocked by a magnetic clutch.

print image and a stagnant ribbon transport in the print phase.
