Abstract: A drop ejector array device includes a first plurality and a second plurality of drop ejectors that are alternatingly disposed along an array direction on the substrate surface. A voltage input terminal and a current return terminal are disposed on the substrate surface. A first power bus line connects the first plurality to the voltage input terminal. A second power bus line connects the second plurality to the voltage input terminal. The second power bus line is electrically connected to the first power bus line by a primary power bus connector line. A first current return bus line connects the first plurality to the current return terminal. A second current return bus line connects the second plurality to the current return terminal. The second current return bus line is electrically connected to the first current return bus line by a primary current return bus connector line.

Abstract: A first swath of first dots is printed, such that each column of first dots is disposed along a first direction and is spaced apart from other columns of first dots along a scan direction. Allowable locations of first dots have an irregular extent along at least a first stitch boundary of the first swath. A second swath of second dots is printed similarly. A first stitch boundary of the second swath is proximate to the first stitch boundary of the first swath to form a first stitched region. Allowable locations of second dots have an irregular extent along at least the first stitch boundary of the second swath that is complementary to the irregular extent along the first stitch boundary of the first swath, where the allowable locations of first dots and the second dots in the first stitched region are substantially not interspersed along the first direction.

Abstract: An inkjet printing system includes an printhead with a nozzle face having nozzles arranged along an array direction. A pressure source is configured to provide a positive or negative pressure to an ink source. A valve is fluidically connected between the ink source and the inkjet printhead. A cleaning station is configured to confront the nozzle face across a gap. The cleaning station includes a cleaning fluid dispenser for dispensing cleaning fluid onto the nozzle face. The cleaning station includes a waste fluid collector having a vacuum inlet that is displaced from the cleaning fluid dispenser in a first direction for collecting dispensed cleaning fluid. The cleaning station includes a blower that is displaced from the cleaning fluid dispenser in a second direction opposite to the first direction. The blower is configured to direct a gas stream along the nozzle face to move dispensed cleaning fluid toward the vacuum inlet.
