Removing a Thermal Paper Roll
Figure 30 Near-empty Paper Roll
A red line on the side of the paper roll indicates the paper supply is 
almost exhausted. Replacement is recommended when the red line is 
visible. If the paper roll is not changed and the paper supply is 
exhausted, the 708-DS / 709-DS gets an out-of-paper signal from the 
printer, and displays an error on the screen.
