Learn how to use the Negative Supply 120 Full Border Scanning Cassette to digitize medium format film, including setup, alignment, and common mistakes.

Quick answer

The Negative Supply 120 Full Border Scanning Cassette lets you capture the entire image area of 120 film, including borders and frame numbers. Use it with a compatible Negative Supply carrier for consistent results.

Why capture the full border?

Including the film border with frame numbers and stock markings adds a professional, archival look to your scans and helps identify the film type later. The Negative Supply cassette is designed specifically for this purpose, holding the film flat and centered.

Compatibility note

This cassette works only with the Negative Supply Basic or Pro Film Carrier 120 MK2. If you use a different carrier, the cassette will not fit. Before starting, confirm your carrier model.

Step-by-step scanning guide

Remove the standard insert from your carrier: Open the Negative Supply Basic or Pro Film Carrier 120 MK2 and take out the default insert. Set it aside. Do not force the cassette; it should slide out freely.
Insert the 120 Full Border Scanning Cassette: Place the cassette into the empty carrier slot. Ensure it clicks or sits flush. The cassette is designed to hold the film flat and centered. If the cassette does not seat evenly, check that you are using the correct carrier model.
Load your 120 film strip: Slide the film strip into the cassette’s film channel, emulsion side facing the light source (usually upward). Gently advance the film until the first frame is centered. Handle the film only by the edges to avoid fingerprints and scratches.
Close the carrier and scan: Close the carrier lid and place it on your scanner. Use your scanning software to preview and adjust focus. The full border, frame numbers, and markings should be visible in the preview. If borders appear cropped, check that the film is fully seated in the channel.
Advance to the next frame: Open the carrier, slide the film strip to the next frame, and repeat. The cassette allows smooth advancement without removing the film. Advance slowly to avoid scratching the film against the cassette edges.
