Adjustment mechanism for development station elements

An electrographic reproduction apparatus development station comprising:

• a housing having walls defining an internal chamber, a portion of said chamber serving as a reservoir for developer material;
• a mixer located in a developer material reservoir within said housing, said mixer including a ribbon blender mounted on a rotatable shaft;
• a developer device for applying developer material to an electrostatic image to be developed;
• a transport mechanism for moving developer material from said reservoir to said developer device, said transport mechanism including a plurality of buckets mounted on a rotatable shaft;
• a drive mechanism for rotating said rotatable shaft of said mixer, said rotatable shaft of said transport mechanism, and said developer device;
• and
• a mechanism for adjusting the location of said rotatable shaft of said mixer and said rotatable shaft of said transport mechanism within said housing, said adjustment mechanism including a first locating device for adjustably positioning said drive mechanism relative to said reservoir of said development station housing, and a second locating device for adjustably positioning said rotatable mixer and said rotatable transport mechanism relative to said development station housing, said second locating device including a spacer member for maintaining a predetermined fixed distance between said rotatable mixer and said rotatable transport mechanism.
