DSD Definition

[LDC242S]

What does DSD stand for when referring to the DSD collar or DSD holder assembly in the process unit? Thanks.

Not sure what the acronym stands for but DSD collars are used to maintain proper distance between drum and developer.

Many years ago I was told the DSD Adjuster means 'Drum Surface Distance' Adjuster.
It's the manual front/rear adjustment for the distance between drum and developer mag roller.
To be honest, I've only ever adjusted this once. Leave it alone if you can.
