    Abstract: A printer includes: a stationary inkjet printhead having an associated print zone; and a feed mechanism for feeding print media past the printhead in a media feed direction. The print media are guided through the print zone such that the print media converge towards the printhead in the media feed direction.

    Abstract: An inkjet nozzle device is configured for constrained symmetric bubble expansion. The inkjet nozzle device includes a firing chamber having a nozzle aperture and a heater element. The heater element extends between an end wall of the firing chamber and a baffle plate facing the end wall. The baffle plate is wider than the heater element and a centroid of the heater element coincides with a midpoint between the baffle plate and the end wall.

    Abstract: A print module configured for interconnection between a positive ink line and a negative ink line via respective inlet and outlet lines. The print module includes: an inlet port; an outlet port; a printhead interconnected between the inlet port and the outlet port; a control valve positioned at the inlet port for controlling an ink pressure in the printhead; an ink pressure sensor for sensing an ink pressure in the print module; and a controller for receiving feedback from the pressure sensor and controlling the control valve. During printing, the ink pressure sensor, the controller and the control valve cooperate to control a backpressure in the printhead within a predetermined backpressure range.

    Abstract: A method of generating print data for an inkjet printhead having a plurality of ink planes. The method includes the steps of: receiving image data for a print job in a printer controller; retrieving keep-wet pattern data for each ink plane of the printhead, the retrieved keep-wet pattern data being determined using one or more input parameters; generating first print data for each ink plane in the printer controller based on the received image data; merging the first print data with the keep-wet pattern data to provide second print data for each ink plane; and sending the second print data from the printer controller to the printhead, thereby causing the printhead to print an image together with a keep-wet pattern. The keep-wet pattern is defined by a plurality of dots printed at a frequency sufficient to maintain hydration of each nozzle in the printhead.
