FAQs

Q: What materials can the KH-375 contour cutting plotter handle?

The KH-375 can cut a variety of materials, including vinyl, heat transfer paper, sticker sheets, cardboard, thin plastics, and reflective films. Avoid cutting overly thick or rigid materials that exceed the machine’s cutting capacity.

Q: What is the maximum cutting width of the KH-375?

The machine supports a maximum cutting width of 375mm (approximately 14.8 inches), making it suitable for small to medium-scale projects such as decals, labels, and signage.

Q: Do I need a computer to operate the KH-375?

Yes. The plotter connects to a computer via USB and requires compatible cutting software (such as CorelDRAW, SignMaster, or other supported vector graphic programs) to send designs to the machine.

Q: Can the KH-375 do contour cutting automatically?

Yes. The KH-375 supports contour cutting for printed graphics. You must use registration marks in your design file, and the software will guide the machine to follow the printed outlines precisely.

Q: Is there a warranty for the KH-375?

Vevor offers a 12-month limited warranty for the KH-375 contour cutting plotter, covering manufacturing defects. It does not cover damage caused by misuse, incorrect installation, or accidental damage.

Q: Can the plotter cut thick vinyl or reflective sheeting?

It can cut standard vinyl and reflective materials, but very thick sheets may require multiple passes or a plotter designed for heavy-duty cutting. Always test a small section before committing to a full project.

Q: Does the KH-375 require special software drivers?

Yes. Before first use, install the included drivers and ensure your computer recognises the plotter. Make sure your software is compatible with the driver to enable full cutting functionality.
