1.3.3. 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.

9
Red / Flash
This illuminates a printing error, such as head open,
paper empty, paper jam, or memory error etc.
1.3.4. Button Operation
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.
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 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
It calibrates the sensor and measures the label length.
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.

Dump 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
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.
