Abstract
In one embodiment, an assembly includes: a print bar; first and second guide rods oriented parallel to one another; a first bracket slidable along the first guide rod and connected loosely to one end of the print bar; and a second bracket slidable along the second guide rod and connected loosely to the other end of the print bar. In another embodiment, a method includes: directly constraining a print bar in Z and theta Y at a first connection; indirectly constraining the print bar in theta Y at a second connection; and neutralizing the theta Y constraint at the second connection through a third connection between the first connection and the second connection.
Claims18
An assembly, comprising:
- a print bar having a first end and a second end opposite the first end;
- first and second guide rods oriented parallel to one another;
- a first bracket slidable along the first guide rod, the first end of the print bar connected loosely to the first bracket at a first connection;
- and
- a second bracket slidable along the second guide rod, the second end of the print bar connected loosely to the second bracket at a second connection.
An assembly, comprising:
- first and second guide rods spaced apart from one another and oriented parallel to one another;
- first and second brackets each slidably mounted to a corresponding guide rod such that the degree of motion of the brackets with respect to the guide rods is constrained in theta X and theta Y;
- a print bar having a first end connected to the first bracket at a first connection and a second end connected to the second bracket at a second connection, the first end of the print bar unconstrained in theta Y at the first connection and the second end of the print bar unconstrained in theta X at the second connection.
A method, comprising:
- directly constraining a print bar in Z and theta Y at a first connection;
- indirectly constraining the print bar in theta Y at a second connection;
- and
- neutralizing the theta Y constraint at the second connection through a third connection between the first connection and the second connection.
