Frequently asked questions

The jam occurs when labels wrap around the printhead or the sensor loses tracking.

If it keeps happening, check for adhesive buildup on the platen roller.

Never use metal scrapers to remove labels, as they can scratch the thermal surface.

Use labels that match the reflective or transmissive sensor specifications.
