Once the error cause is rectified, the printer automatically goes into
the ON LINE mode. Alternatively, press the ON LINE button, unless automatic transition
to the ON LINE status after the error cause is removed is set.
Error solution
1. Inserting the paper
a. Open the paper compartment
with the use of the button.

PRINTER STATUS SIGNAL EMERGENCIES
USING THE PRINTER:
PREPARING THE PRINTER FOR
OPERATION
c/d
I. RS232C Cable Interface
1. Connect the cable
2. Switch the printer on, pushing the ON button. Green LED will light up.
3. If a red error indicator is active, you should check and get rid of the problem - then the green
ON LINE status indicator is activated. Then the printer will be ready for print.
4. The printer, with a delay, after the printing process ends and after an idle period,
goes into sleep mode automatically, which is signalled by a relevant indication.
5. In case when the idle period is expected to be longer, switch the printer off with the use
of the OFF button.
II. Bluetooth Wireless Interface
1. Switch the printer power supply on with the use of the ON button. Green LED will light up.
2. Prior to connecting to the cooperating device, pair it with the printer. In order to connect
on demand, provide the key - PIN no. provided on a label sticked in a visible location on
the printer, or number following the PRN on the submitted device, if only one printer is
being connected.
3. Then, the wireless interface is automatically initiated, and the printer goes into “ready” state.
Once data is transferred, diode changes its color to blue. Then, the document is printed out.
4. In case when the idle period is expected to be longer, switch the printer off with the use of the
OFF button.
III. USB Interface
1. Connect the USB cable
2. Switch the printer power supply on with the use of the ON button. Green LED will light up.
Once the printer is configured, send the printing data. The LED colour will change, into emerald.
Once the printing process is finalized, the printer automatically enters the sleep mode, once the
programmed delay time passes. This is signalized by a purple (standard sleep mode) or blue
(deep sleep/hibernation mode) blinking indicator.
Transferring the printing data from an external device, through the RS interface,
will automatically initiate the printer (green indicator is going to be lit up),
and the printing process is carried out. In hibernation mode, this indicator has a blue
color and it blinks. In order to establish a USB connection, you should press the
ONLINE or FF button, to wake the printer up.
Setting the printer driver up in Windows:
1. USB communication.
USB interface, flash storage*, virtual LPC USB com port and printer drivers are installed
automatically. Once the setup is completed, one should get the printer driver updated,
by indicating its location in the printer memory. Alternatively, the driver may be downloaded from
the
* Printer’s flash storage is visible via the PC, when the maintenance button is pressed for
a moment simultaneously with pressing the ON LINE and FEED buttons.
In case of Windows 8 and Windows 10 operating systems, forcing the printer
to include electronic signature should be turned off.

In case when the battery is fully charged, the printer is capable
of printing 360 meters of paper (with 25% filling with print, at the
temperature of 20°C).
The battery charge status is signalled 5 seconds after the printer is
switched on, or after the printing process is completed.
Continuous glow - battery full (allows the user to print at least 80 meters
of paper, up to 360 meters).
Blinking glow (slow blinking - one blink per second) battery low
(40 meters printing capacity max - 4 meters - min.).
Should the condition above be present, finish the work and connect
the charger!!!
Blinking glow (4 quick blinks per one second) - end printing immediately
and charge the battery.
The battery - 6.4 Ah, 7.4V - of the printer is being charged with the use
of an external Li-Ion 8.4V 1.2A charger, up to the full charge, in 6 hours.
Charging instructions:
1. Plug the charger into a 230V grid outlet.
Green diode lights up.
2. Plug the charger into the printer. The charging process is signalled
with the change of the diode color, from green to red.
3. Once the charging process is completed, the diode yet again changes
its color, from red to green.
If the indicator is red, with dimming, which is simultaneously
connected to emission of a sound signal - that means that an error
occurred during the operation.
Number of sound signals and dimming in a 4-sec. cycle indicates the type of
error, in accordance with the list below.
