1. Permanent measures to prevent dropout copies and edge transfer misalignment
1.Model name: Z-20, 25, 27
2.General: A DN mylar and DN holder spacer were mounted onto the DN holder unit, from the first
unit of mass production. This was a provisional measure to prevent dropout copies and
edge transfer misalignment. The shape of the DN holder has now been changed as a
permanent measure. Current and new DN holders are interchangeable.
