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:
