Black mark imprint position is on the front side of the receipt when using
mark paper. The black mark reflectivity is no more than15%, the other parts of
paper reflectivity should be more than 85%.There are not any patterns in black
mark area, such as ad, and the mark size shall be satisfied with requirements
as below:
Paper using attention
- Please use good quality paper, otherwise, it will effect printing quality and even reduce printer head life.
- Don’t make the paper stick on axis.
- Paper will be fading out or reduced thermal sensitivity if it is polluted by chemical or oil, which will affect printing effects.
- Don’t use nail or hard things to clash printing paper, otherwise, it will be fade out.
- Paper will be fading out if the environment temperature exceeds 70°C. So please take note the temperature, humidity and illumination effects.

Printing self-test page
- Make sure the printer loaded paper roll correctly.
- Press down [FEED] button and hold on, then power on the printer, the printer will print a self-test page.
Set Ethernet port IP Address.
The printer’s Ethernet IP address can be set directly via printer inserted web
setting page. The operation steps are as below:
- Connect printer and PC in the same Ethernet LAN.
- Print a printer self-test page to get printer recent IP address (self-test page printing operation method refers to “4.8 printer self-test” instruction): You can find the printer’s IP address is same as 192.168.1.87 in the self-test page“IP address: 192.168.1.87”
- Set network card IP address in PC and printer IP address as different IP address in the same network segment.(Such as 192.168.1.xxx, xxx is a number among 1 to 254);
- Please enter the address “http://printer IPaddress” in browse of PC after making sure that printer connects with Ethernet.(e.g.: If printer IP address is “192.168.1.87”, please enter “http://192.168.1.87”), then press Enter key, and open the Ethernet port setting page in the browser as below:
- Click “Configure Interface” link in the left side, then enter the modified target IP and click “save” button to save setting. Click “Reboot” button to reset printer if you want the setting to take effect.
- Enter the new IP address as the above step 4 procedure, and re-open printer Ethernet port setting web page, then click “Printer Status” link in the left side. And click “Printer Test Page” button to print self-test page, and check the IP Address contents in the self-test page is right or not.
