1.2.2. LED

LED Color

Description

Green/ Solid

This illuminates that the power is on and the device is

ready to use.

Green/ Flash

This illuminates that the system is downloading data

from PC to memory and the printer is paused.

Amber

This illuminates that the system is clearing data from

printer.

Red / Solid

This illuminates printer head open, cutter error.

Red / Flash

This illuminates a printing error, such as paper empty,

paper jam, ribbon empty, or memory error etc.

1.2.3. Button

Feed

 Press the button when the LED is green.

 It feeds the label to the beginning of the next label.

Pause

 Press the feed button during printing

 The printing job is suspended.

Ribbon Sensor and

Gap/Black Mark

Sensor Calibration

1. Turn off the power switch.

2. Hold on the button then turn on the power switch.

3 Release the button when LED becomes red and blinking.

(Any red will do during the 5 blinks).

 It will calibrate the ribbon sensor and gap/black

mark sensor sensitivity.

 The LED color will be changed as following order：

Amber  red (5 blinks)  amber (5 blinks) 

green (5 blinks)  green/amber (5 blinks) 

red/amber (5 blinks)  solid green

Note:

Please select gap or black mark sensor by GAP or

BLINE command prior to calibrate the sensor.

For more information about GAP and BLINE command,

please refer to TSPL2 programming manual.

Mode

1.Turn off the power switch.

2. Hold on the button then turn on the power switch.

3. Release the button when LED becomes amber and

blinking. (Any amber will do during the 5 blinks).

 The LED color will be changed as following order.

Amber  red (5 blinks)  amber (5 blinks) 

green (5 blinks)  green/amber (5 blinks) 

red/amber (5 blinks)  solid green

 It calibrates the sensor and measures the label

length and prints internal settings then enter the

dump mode.

Note:

Please select gap or black mark sensor by GAP or

BLINE command prior to calibrate the sensor.

For more information about GAP and BLINE command,

please refer to TSPL2 programming manual.

Printer Initialization

1. Turn off the power switch.

2. Hold on the button then turn on the power switch.

3. Release the button when LED turns green after 5 amber

blinks. (Any green will do during the 5 blinks).

 The LED color will be changed as following:

Amber  red (5 blinks)  amber (5 blinks) 

green (5 blinks)  green/amber (5 blinks) 

red/amber (5 blinks)  solid green

Note:

Always do gap/black mark sensor calibration after

printer initialization.

Force Black Mark

Sensor Calibration

1. Turn off the power switch.

2. Hold on the button then turn on the power switch.

3. Release the button when LED turns green/amber after 5

green blinks. (Any green/amber will do during the 5

blinks).

 The LED color will be changed as following:

Amber  red (5 blinks)  amber (5 blinks) 

green (5 blinks)  green/amber (5 blinks) 

red/amber (5 blinks)  solid green

Force Gap Sensor

Calibration

1. Turn off the power switch.

2. Hold on the button then turn on the power switch.

3. Release the button when LED turns red/amber after 5

green/amber blinks. (Any red/amber will do during the 5

blinks).

 The LED color will be changed as following:

Amber  red (5 blinks)  amber (5 blinks) 

green (5 blinks)  green/amber (5 blinks) 

red/amber (5 blinks)  solid green

Skip AUTO.BAS

1. Turn off printer power.

2. Press the FEED button and then turn on power.

3. Release the FEED button when LED becomes solid

green.

 The LED color will be changed as following:

Amber  red (5 blinks)  amber (5 blinks) 

green (5 blinks)  green/amber (5 blinks) 

red/amber (5 blinks)  solid green

4. Printer will be interrupted to run the AUTO.BAS program.
