Dual brush cleaner retraction mechanism and variable inertia drift controller for retractable cleaner

An apparatus for cleaning particles from a movable surface of a multipass image on image printing machine, comprising:

• cleaning brushes, including a first cleaning brush and a second cleaning brush, said first cleaning brush being located upstream from said second cleaning brush in a direction of motion of the surface;
• and
• a mechanism for pivotally supporting said first cleaning brush and said second cleaning brush, having an actual pivot point on an axis parallel to and above the surface and perpendicular to the direction of motion of said mechanism enabling said first cleaning brush and said second cleaning brush to sequentially retract from and engage with the surface, said mechanism comprises a multibar linkage, having a six bar linkage, with each bar of said multibar linkage being pivotally connected to another bar of said multibar linkage, said six bar linkage comprises:
• a frame link being the endplate of the printing machine for said first brush and said second brush;
• a first follower link for said first brush having a first follower pivot, said first follower link having one end pivotally connected to one end of said frame link at the first follower pivot;
• coupler links including a first coupler link and a second coupler link, said coupler links being compressible, said first coupler link, having an extension connected to one end, the extension being pivotally connected to said second coupler link on an end opposite said first coupler link and said first coupler link being pivotally connected to said first follower link on an end opposite the extension;
• a crank link having a driving means, being coupled on one end to an intersection of said first coupler link and the extension on one end, and being coupled on an opposite end of said crank link to a crank pivot, said crank link being mounted on said frame link between said first brush and said second brush;
• and
• a second follower link for said second brush having a second follower pivot, said second follower link having one end pivotally connected to another end of said frame link at the second follower pivot, opposite the end of said frame link attached to the first follower pivot, said second follower link being pivotally connected to said second coupler link on an end opposite to the first coupler link.
