Abstract: A printer is configured with at least two printheads that are separated from one another in a cross-process direction by an integral multiple of printhead widths. This configuration enables parallel swaths of material to be ejected and then movement of the printheads in the cross-process direction by a distance corresponding to one or more integral numbers of the printhead width enables the area between the swaths to be completed and the area outside of the original swaths printed.

Abstract: A method of operating a three-dimensional object printer includes generation of a printed predetermined test pattern on a substrate in the printer with a plurality of ejectors in a printhead. An image sensor generates image data of the printed test pattern and a controller identifies a z-axis distance between the printhead and the substrate that receives the test pattern with reference to an identified dispersion between cross-process direction distances separating printed marks in the test pattern.

Abstract: A printer includes a printhead configured to eject high viscosity material and refill a reservoir in the printhead with high viscosity material. The printhead includes a transducer having an electroactive element and a member to which the electroactive element is mounted. An electrical signal activates the electroactive element to move the electroactive element and the member in the reservoir of high viscosity material. This movement thins the high viscosity material and enables the printhead to eject the thinned material while refilling the reservoir. The apertures through which the thinned material is ejected share a common manifold without separate chambers for each of the apertures.

Abstract: A printer includes a printhead configured to eject high viscosity material and refill a manifold in the printhead with high viscosity material. The printhead includes a layer having an opening to form a reservoir to hold a volume of a high viscosity material and at least one member positioned within the receptacle formed by the opening in the layer. The at least one member has an electroactive element mounted to the member, and an electrical signal generator is electrically connected to the electroactive element. A controller operates the electrical signal generator to activate selectively the electroactive element with a first electrical signal to move the at least one member and thin the high viscosity material adjacent the at least one member to enable the thinned material to move away from the at least one member.

Abstract: An aqueous inkjet printer is configured to evaluate and adjust multiple components within the printer with reference to image data of the surface of a rotating member obtained at different times during a single print cycle. The print cycle can be performed in a multiple pass manner to enable a single optical sensor to be used for generation of the image data. Alternatively, the print cycle can be performed in a single revolution of the rotating member and multiple optical sensors positioned about the rotating member to generate the image data.
