~JG - Graphing Sensor Calibration

Overview

The ~JG command performs sensor calibration and prints a visual graph (media sensor profile) of the sensor values. Provides graphical feedback of sensor readings across label length for advanced troubleshooting and setup optimization.

Syntax

~JG

Parameters

None

Description

• Performs full sensor calibration
• Measures label length
• Calibrates media and ribbon sensors
• Prints graphical sensor profile
• Visual troubleshooting aid

Examples

Generate Sensor Profile

~JG

Prints calibration data and sensor graph on label.

Graph Output

Shows:

• Sensor readings across label
• Media sensor threshold
• Ribbon sensor threshold
• Gap/mark detection profile
• Sensitivity visualization

Uses for Graph

Troubleshooting

• Identify sensor dead zones
• Detect media reflectivity issues
• Diagnose gap detection problems
• Optimize sensor thresholds

Setup Verification

• Confirm proper media detection
• Validate gap positioning
• Verify sensor alignment
• Document baseline performance

Interpretation

Good Graph

• Smooth curve across label
• Clear gap detection
• Consistent sensor readings
• No anomalies

Problem Indicators

• Flat line (sensor not detecting)
• Inconsistent readings (alignment)
• Reversed values (inverted sensor)
• Spikes (debris or damage)

Usage Notes

• Consumes one label for output
• More detailed than ~JC
• Provides visual reference
• Useful for documentation
• Keeps graph for records
