7.1.3.2 Charge printer
Only use the provided AC-adapter to charge the printer. Please note: a new set of batteries reaches
its full capacity after 3 full charge- and discharge cycles. Deep discharge damages the battery.
When a battery was deeply discharged, charging can stop after 30 minutes. In this case, restart
charging by replugging the AC-adapter.
When the battery is faulty or “consumed”, replace it with a original one.
7.1.3.3 Self test of printer
To check the printer without the ZFG 3.0, it is possible to run a self test. Disconnect the Printer
from the ZFG 3.0. Switch off the printer (wait one minute). Press <FEED/ENTER> button, longer
than 3 seconds, a test printout will be created. Firmware version and a set of characters will be
printed. When no printout was done or the printout is faulty please note section 7.1.3.4 Problems
using the printer and 7.1.3.5 Change paper.
7.1.3.4 Problems using the printer
When the printer is not detected by ZFG 3.0 following screen appears:
In this case, it is not possible to create printouts. When the steps from section7.1.3.1 Usage of the
printer were noted, check if the power supply of the printer is ensured. Doing this, switch off
ZFG 3.0 and press the <FEED/ENTER> button on the printer. The power supply is ok, when the
LED flashes green. Charge the battery if the LED stops flashing after less than 1 minute or LED
does not respond to the button.
Perhaps, the paper is empty. In this case the LED flashes red. Fill in a new roll of thermal paper (see
section 7.1.3.5 – Change paper).
7.1.3.5 Change paper
To change the paper, open the cap of the paper compartment. Remove the empty roll of thermal
paper (or the capsule on which the paper was rolled) and replace it with a new one. Please note, that
the roll is in that way inserted in the printer, that it will be unrolled from the bottom (see Picture 6).
Place the beginning of the roll above the tear-off edge. Finally, close the paper compartment by
pushing the cap.
When printing fails after changing the paper, it may have been inserted
incorrectly (upside down) or it is not thermal paper.
