Replenisher mechanism interface

In association with a mechanism for replenishing marking particles from a receptacle to a remote reservoir of a development station of a reproduction apparatus, said replenisher mechanism having a housing for receipt of marking particles within said housing, and said receptacle having a cap with a sliding mechanism forming a seal that is used to open the receptacle for emptying, a plurality of guiding features, and locking features, an interface member providing flow communication of marking particles between such marking particle receptacle and said housing, said interface member comprising:

• a casting defining a flow communication passage for marking particles;
• a plate attached to said casting at an angle to the horizontal to define an angled entrance to said casting;
• and
• a member, associated with said angled entrance plate, having features cooperating with said guiding features and locking features of said receptacle cap for guiding and holding the marking particle receptacle at a corresponding angle to the horizontal when the receptacle is installed on the angled entrance plate, whereby the angled orientation of the marking particle receptacle lets air percolate into the marking particle receptacle while the receptacle is emptying, allowing the marking particles to flow freely out of the receptacle.
