Compatibility checklist

Sensor type decides whether the printer can find the next label

Incorrect sensor stock causes skipped labels, drift, failed calibration, or labels printing across the gap. Match the media format to the printer sensor before approving the roll.

Gap labels

Die-cut labels with a visible gap are common for shipping, inventory, and product labels. The printer sensor must reliably detect the gap at the chosen speed.

Black mark labels

Black mark media uses a printed mark on the liner or back of the stock. It is useful for some continuous or shaped stock, but the mark must align with the sensor.

Continuous stock

Continuous labels need cutter, tear, or software control. They are flexible, but they need a different setup than fixed die-cut labels.

Planning checklist

Confirm sensor position and calibration method.
Ask whether the media has a gap, notch, black mark, or no mark.
Print at production speed during the sample test.
Keep a photo of the approved liner or back mark.

Common failure points

Switching media format without recalibrating the printer.
Assuming a black mark will align with every sensor position.
Using continuous stock where software or cutter settings are not ready.

Supplier questions

Does the stock use gap, notch, black mark, or continuous sensing?
Where is the mark or gap located relative to the printer sensor?
What calibration process should be used for the sample roll?
