Abstract: A fluid ejection system can include a carriage base that includes a first pen slide at a bottom rear of the carriage base, a second pen slide at a front of the carriage base, and a pen guide at a top rear of the carriage base, the pen guide can include a guide portion to engage a substantially vertical portion of a back corner of a pen, a blocker portion to engage a substantially horizontal portion of the top back corner of the pen, and a pen guide corner formed between the guide portion and the blocker portion to hold a top back corner of a pen substantially in place during an angular loading of the pen.

Abstract: The present specification describes a manifold for a fluid ejection system. The manifold includes a rotational connector on a first side surface, a plurality of pen interconnects on a bottom surface of the manifold, and a sliding surface on a top surface of the manifold. The sliding surface is to accommodate a fluidic interface. Sliding the fluidic interface along the sliding surface extends needles from the fluidic interface through the plurality of pen interconnects into a plurality of pens.

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.

Abstract: An inkjet printer comprising an ejection device, movably provided along a print zone and a spit zone, a printer controller to control ejection device maintenance, a spittoon located in the spit zone to receive maintenance ink ejected by the ejection device in the spit zone when ejection device maintenance is performed, is provided. The printer controller is to set a random spit position within the spit zone at which the ejection device is to eject the maintenance ink into the spittoon and to cause the ejection device to move to the set random spit position and to eject the maintenance ink into the spittoon at the random spit position.

Abstract: The present specification describes a carriage base for a fluid ejection system. In some examples, the carriage base includes a first pen slide at the bottom rear of the carriage base. In some examples, the carriage base includes a second pen slide at the front of the carriage base. In some examples, the carriage base includes a pen guide at the top rear of the carriage base to hold a top back corner of a pen during an angular loading of the pen.

Abstract: In an example, a space adjuster may comprise a cam shaft, a first fin disposed on a first end of the cam shaft, a second fin disposed on a second end of the cam shaft, opposite from the first end, and a cam lug disposed on the cam shaft in between the first end and the second end. The first fin may have a first profile to transfer a first longitudinal force into a first rotation of the cam shaft, and the second fin may have a second profile to transfer a second longitudinal force into a second rotation of the cam shaft, opposite to the first rotation. A cam surface of the cam lug may be spaced increasingly farther away from a longitudinal axis of the cam shaft throughout the first rotation of the cam shaft.
