Abstract

This idea proposes an improved method for supporting/holding a mono-filament cleaning element for use in a solid-ink (hot melt) printhead cleaning subsystem. The existing cleaning subsystem design utilizes two torsion springs to tension a mono-filament to enable placement of it within a specified target landing zone as it engages against the print head surface. This proposal allows the mono-filament to move in an arc as it engages with the print head surface. This idea addresses the problem of unwanted vertical movement by modifying the torsion spring configuration such that it pivots about a hinged leg 90 degrees to the existing rotational torsion loading design. This effectively eliminates any vertical movement of the mono-filament as it engages into the print head surface.

Near Single plane loading of a filament surface cleaning element in a printhead cleaning system

This idea proposes an improved method for supporting/holding a mono-filament cleaning element for use in a solid-ink (hot melt) printhead cleaning subsystem. The existing cleaning subsystem design utilizes two torsion springs to tension a mono-filament to enable placement of it within a specified target landing zone as it engages against the print head surface. This proposal allows the mono-filament to move in an arc as it engages with the print head surface. This idea addresses the problem of unwanted vertical movement by modifying the torsion spring configuration such that it pivots about a hinged leg 90 degrees to the existing rotational torsion loading design. This effectively eliminates any vertical movement of the mono-filament as it engages into the print head surface.

This proposal allows for the near single plane deflection motion of a torsion spring filament surface cleaning element. The previous concepts and designs loaded with an arc sweeping deflection motion that generates both horizontal and vertical motion during deflection.  This idea provides near single plane motion during loading deflection by allowing the torsion springs to pivot around hinged leg axes during loading.  Previous designs had greater vertical displacements due to torsion deflect around fixed leg positions which exhibit rotational loading.

Below are notebook sketches of the original concept. It...
