  • Lock pins for carriage assemblies of printing devices
    Patent number: 11305568
    Abstract: Examples techniques to restrict unlatching of manifolds of carriage assemblies in printing devices are described. In an example, a carriage assembly of a printing device comprises a carriage structure defining an opening to house a printhead and a manifold coupled to the carriage structure. The manifold covers the printhead in a latched position and allows access to the integrated printhead in an unlatched position. A lock pin is mounted on the carriage structure, the lock pin being slideable to a first position and a second position with respect to the manifold along the carriage structure. In an example, the lock pin restricts unlatching of the manifold with the carriage structure in the second position.
