Elastic Bending Mechanism for Bi-Directional Adjustment of Print Head Position

An adjustment mechanism comprising:

• a screw that includes
• a first threaded segment that is connected to a threaded feature of a rigid body of a printer, and
• a second threaded segment that is connected to a threaded feature of a flexible body coupled to a print head of the printer;
• and
• an indexing wheel through which the screw extends,
• wherein rotating the indexing wheel causes pressure to be applied to, or relieved from, the flexible body, thereby displacing the print head.

An adjustment mechanism comprising:

• a differential screw that includes
• a first threaded segment that is connected to a threaded feature of a rigid body, the first threaded segment having a first pitch, and
• a second threaded segment that is connected to a threaded feature of a flexible body coupled to a movable component, the second threaded segment having a second pitch;
• and
• an indexing wheel through which the differential screw extends,
• wherein rotating the indexing wheel causes pressure to be applied to, or relieved from, the flexible body, thereby enabling bi-directional adjustment of the movable component.

A method comprising:

• installing a first threaded segment of a differential screw within a threaded feature of a rigid body of a printer;
• installing a second threaded segment of the differential screw within a threaded feature of a flexible body coupled to a print head of the printer;
• and
• enabling a position of the print head to be adjusted by rotating an indexing wheel through which the differential screw extends,
• wherein rotating the indexing wheel in a first direction causes pressure to be applied to the flexible body, and
• wherein rotating the indexing wheel in a second direction causes pressure to be relieved from the flexible body.
