Just to clarify, the paper runs the whole length of the 120 roll, but on 220 film (same as 120 just twice the film length) the paper is only beginning and end of the roll to keep the roll diameter small enough.
Your Diana isnt designed for 220, which is fine because their is so little available and it costs 3x as much as 120.
