How to Calibrate Label Length on Automatic Labeling Machine (Step-by-Step)
Correct label length calibration is crucial for ensuring your automatic labeling machine dispenses exactly one label per bottle—no more, no less. Misaligned or incomplete labels can hurt product quality and brand image, so follow this step-by-step guide to calibrate your machine like a pro.
Tools You’ll Need
- Your automatic labeling machine (powered off initially)
- Label rolls (the exact type you’ll use for production)
- A ruler (optional, for verifying label length)
Calibration Steps
- Prepare the Machine: Turn on the machine and navigate to the touch screen’s main interface. Load the label roll securely, ensuring it’s aligned (no tilting or looseness)—poor label roll placement can affect calibration.
- Reset the Label Length Value: On the touch screen, find the “Length of Label” parameter and set it to 0. This resets the sensor’s default reading.
- Run a Label Test: Click the “LAB. Test” button on the touch screen. The machine will dispense a label—observe whether it’s a full label or partial.
- Adjust the Value: If the dispensed label is too short, gradually increase the “Length of Label” value (e.g., add 5mm at a time). Click “LAB. Test” again to check. Repeat this process until the machine dispenses exactly one full label (no excess or missing parts).
- Verify Alignment: After calibrating length, run a test with a bottle to ensure the label is aligned correctly. Adjust the “Position of Label” parameter if needed.
- Save the Settings: Once calibrated, click the “Save” button on the touch screen to store the settings for future use (especially useful if you use the same label type regularly).
