2. The printer is on and ready to use.

No action necessary.

3. The printer is paused.

Press the feed button to resume printing.

4. The LED is on red blinking.

If the LED is on red blinking, which means that either label or ribbon runs out.

Label runs out:

Load a roll of label and follow the instructions as following and then press the feed button to resume printing.

1. Insert a paper roller into a paper roll

2. Open the printer’s top cover by releasing the green cover lock tabs located on each side of the printer and lifting the top cover. A support bar at the rear of the printer will hold the printer top cover open.

3. Place a roll of paper onto the center of the paper roll mount.

4. Feed the paper, printing side face up, through the Teflon bar and the paper guide and pass over the platen.

5. Adjust the green center-biased paper guides in or out so they are slightly touch the edges of the label backing.

6. To close the printer top cover, lift the cover slightly and pull the support bar forward toward the front of the printer. C lose the printer top cover slowly and make sure the cover locks latch securely.

Ribbon runs out:

Load a roll of ribbon and follow the instructions as following and then press the feed button to resume printing.

1. Push down on the ribbon access cover to unlock and open the cover

2. Place a paper core on a ribbon rewind spindle.

3. Mount the ribbon rewind paper core on the front hubs.

4. Install a ribbon on the ribbon supply spindle.

5. Mount the ribbon supply spindle on the rear hubs .

6. Attach the ribbon leader to the ribbon rewind paper core.

7. Rotate the ribbon rewind paper core until the ribbon leader is thoroughly, firmly encompassed by the black section of the ribbon.

8. Close the ribbon access cover.

Ribbon sensor or ribbon rewind encoder error

Remove the ribbon, close the ribbon mechanism then turn off/on the printer power. The printer will be switched to thermal direct mode automatically.

If the printer LED is still on red blink, please check the following:

A. Is a paper core installed on the ribbon rewind spindle?

B. Is ribbon installed correct along the ribbon path?

C. Is the ribbon too transparent?

D. Is the rib of the ribbon spindle is broken?

E. Is the ribbon gear broken or worn?

F. Turn off printer power. Rewind the ribbon spindle by hand. Does the spindle rewind smoothly by hand? If the ribbon spindle doesn’t rewind smoothly, please replace the ribbon mechanism.

G. Is the DC motor broken?

H. Is the ribbon sensor broken?

Measure the current of pin2 of JP19. If the ribbon detects the ribbon, it should be 5V DC; otherwise, it should be 0V DC.

I. Is the DC motor encoder sensor broken?

Measure the current of pin2 of JP9. When sensor detects the gap of encoder, it is 5V DC; otherwise it should be 0V DC.

Check if there is any black lubricant oil filled between gaps, which may cause error.

J. Check the DC motor driver IC (U13) on the main PCB ass’y . If it can function all right, please replace the main PCB ass’y.

Paper sensor error

Please check the following items:

A. Is label installed correctly? Please refer to previous 4. The LED is on red

blinking – Label runs out to load a roll of label and then press the feed button to resume printing.

B. Is there any label stuck on the label sensor? Is there any pre-printed logo on the label? Please initialize to reset the system.

Main PCB ass’y, feed gap sensor or black mark 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 feed gap sensor may be broken. Please change the feed gap sensor receiver first because the receiver sensor failure rate is higher than the transmitter sensor.

5. The printer setting runs error.

Printer setting runs error:

Refer to the chapter of Initialization in Interface Specification to reset the system.

6. Continuous feeding labels

The printer setting may go wrong. Please do the “Initialization” and “Feed Gap and Black Mark Sensor Calibration”. (Refer to Interface Specification).

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.

Printed by enclosed BarTender software

This may be driver conflict problem. Please remove all the drivers in the printer folder and then re-install the driver for your printer.

Printed by printer command.

This problem is caused by incorrect syntax commands. B-SV4T printer will ignore incorrect syntax commands. Please set the printer to the dump mode and make sure the printed command is identical to the commands sent from the application software.

5-3

The printer serial port setting is not correspondent to the PC’s setting

Please do the configuration by TPCL commands.

9. Poor print quality

The head maybe dirty. Clean the thermal print head.

Adjust the print density setting.

Ribbon and paper media are not compatible .

10. Stepping motor does not feed label

Does stepping motor function normally?

Are U11, and U12 (3717 driver IC) of main PCB ass’y broken?

11. No 5V DC on main PCB ass’y.

Is switching power broken?

Is main PCB ass’y U3 broken? Please replace a new main PCB ass’y .

12. Cutter functions abnormally.

Cutter is not activated

Cutter is broken or the main PCB ass’y is broken. If it still has problem after a new cutter replaced, the U14 (driver IC) or U5 IC on the main PCB ass’y may be broken.

13. Black mark can’t be detected properly

Please check the position of the black mark. Is the width of black mark too thin to be detected? The suggested black mark width is 12 mm.

Does the sensor function properly?

Measure the current of pin3 of Q9. It is 5VDC when the black mark is detected; otherwise it should be 0V DC. If the voltage is correct as above mentioned and the black mark still can’t be detected, CPU may have some problem.
