1. Unpacking of thermal receipt printer

Inspect the parts:

Please check the included parts upon unpacking. If any are missing, please contact the supplier or manufacturer.

2. Thermal receipt printer connection method

(1) Ensure that both the printer and the PC host are turned off. Plug the matching data communication cable into the printer's data port and the other end into the PC host's USB/network port.

(2) If the cash drawer is equipped with an electrically openable cash drawer, plug the RJ-11 connector on the cash drawer into the cash drawer port of the printer (the cash drawer must be compatible with the printer’s cash drawer drive specifications).

(3) A dedicated power adapter for connecting the printer.

Please use the dedicated power adapter included with the package. The connection diagram is shown below:

Notice:

(1) First, plug in the printer's power cord (DC24V), then connect it to the AC220V power supply, and then turn on the power switch. Do not reverse the order, otherwise the machine will be damaged.

(2) Using an inappropriate power adapter can degrade print quality or even damage the printer.

(3) Do not connect the telephone line to the cash drawer interface, otherwise the printer and telephone may be damaged.

(4) When plugging or unplugging the printer power cord, hold the printer power connector by the arrow (do not hold the printer power cord by the cord itself). Forcibly pulling the printer power connector cord may damage the printer or power adapter.

3. Installation of paper rolls for thermal receipt printers

The 80 series printers use 80.0 mm thermal paper rolls and feature an easy-load paper mechanism, making paper loading very convenient.

The installation method for thermal paper is as follows:

(1) Open the printer cover.

(2) Place the thermal paper roll into the paper loading compartment as shown in the figure below.

(3) Pull a small section of the printing paper out of the box and close the top cover.

(4) Use the machine's blades to tear off the excess paper rolls.
