to resume printing.
B. Is there any label stuck on the label sensor? Is there any pre-printed logo on
the label? Please refer to 5.2 Initialization to reset the system.
If the pre-printed logo or text influences the auto gap calibration function, please

C:\>MODE COM1 96,N,8,1 <Enter>
C:\>COPY CON COM1 <Enter>
SET GAP 1 <CTRL>< Z>
Main board, gap sensor or black sensor failure.
 Measure the current of pin3 of Q8. It is 5V DC when the label is detected and
0V DC for gap. If the voltage is not correct as above mentioned, the U23 ,CPU
(U1) or gap sensor may be broken. Please change the gap sensor receiver
first because the receiver sensor failure rate is higher then the transmitter
sensor.
5. The printer setting runs error.
Printer setting runs error:
Refer to 5.2 Initialization to reset the system.
6. Continuous feeding labels
 The printer setting may go wrong. Please do the “Initialization” and “Gap and

7. No print on the label
 Is the label or ribbon loaded correctly? Refer to No, 4 Label runs out and
Ribbon runs out to load the paper or to load the ribbon.
 Does the ribbon run out?
 Is the thermal head connector connected?
 Is the thermal head broken? Check it by printer self-test printout.
 Is main PCB U21, U15, Q1 broken?
8. Printer does not print.
