10. LED keeps at solid amber.

 Is switching power broken?

 Is main board broken? Please replace a new main board.

 Try to update the firmware on line. Press the FEED and power on the printer

at same time. Press the FEED again while the first green LED is on. Finally,

transmit the firmware program to the printer from PC.

11. Cutter functions abnormally.

Cutter is not activated (other error)

At first, check if cutter is broken or the main PCB is damaged. If it still has problem

after changing a new cutter, perhaps the U30 (driver IC), U28 IC or U34 on the

main board was broken. Otherwise, check if the pin 28 of U2 (CPU) is good.

12. Black mark can’t be detected properly (out of paper or paper jam)

 Please check if the position of the black mark on label is correspondent with

black mark sensor.

 Is the width of black mark on label too thin to be detected? The

recommended black mark width is wider than 12 mm.
