3. Core Technology Advantages

1. Precision heating system

Adopts step-type heating control technology, which is realized through three independent temperature zones:

Preheating zone: pre-increase the surface temperature of the medium

Main heating zone: accurately control the color reaction

Cooling zone: quickly solidify the printed content

This design improves energy utilization by 35%, while avoiding premature aging caused by excessive heating of thermal paper.

2. Intelligent compensation mechanism

The built-in real-time feedback system includes:

Temperature sensor (±1℃ accuracy)

Voltage fluctuation compensation circuit

Automatic detection of dot matrix damage

When abnormalities are detected in some heating points, the system automatically adjusts the energy output of adjacent points to ensure consistent printing quality.

4. Special function analysis

1. High-density coding support

Can perfectly present 0.2mm wide barcode lines

Support the latest specifications of Micro QR code (version M1-M4)

Achieve clear readability of 1mm high letters

2. Multi-media adaptation

Automatically identify and optimize the following media printing parameters through dynamic energy adjustment algorithm:

Ordinary thermal paper (60-80g/㎡)

Synthetic paper (PET/PVC substrate)

Special label (security paper with anti-counterfeiting coating)

5. In-depth processing of typical faults

1. Vertical white line fault

Root cause:

Heating point contamination (90% of cases)

Drive circuit failure (7%)

Poor data cable contact (3%)

Professional processing flow:

Use a special cleaning stick (PN: ZT-410-CLN) for deep cleaning

Run the print head self-test mode (through ^HQT command)

If not resolved, use a multimeter to detect the heating point resistance (normal value: 1200±50Ω)

2. Blurred edge problem

Optimization solution:

python

# Pressure adjustment reference value (based on medium thickness)

def adjust_pressure(thickness):

if thickness < 0.1mm:

return 2.5N/cm²

elif 0.1-0.2mm:

return 3.0N/cm²

else:

return 3.5N/cm²
