It depends on the scanner. If yours is a flatbed the key concept may be to not use the film holder provided but instead to lay the strip of film on the glass, it may be necessary to make a special arrangement to bring the film slightly up off the glass for best focus.
If your scanner has a slot this may be more tricky and possibly not possible!
Complications may arise with a flatbed scanner when the film holder includes physical registration points that the scanner identifies prior to the scan, if these are absent, because the film holder is not used, the scanner may refuse to start. Sidestepping this may be possible with ingenuity.
