摘要： An inkjet printhead assembly includes a repositionable shutter mechanism adapted to block a slot through which drops of ink ejected from the array of nozzles pass before they impinge on the print medium. The shutter mechanism includes a frame, and a repositionable shutter blade extending in a cross-track direction having first and second tabs affixed to its ends. At least one of the first and second tabs includes a lever arm. The shutter blade is adapted to rotate around a pivot axis passing through the first and second tabs. An actuator is configured to apply a force to the lever arm, thereby pivoting the repositionable shutter blade about the pivot axis between a first pivot position where the shutter blade blocks the slot and a second pivot position where the shutter blade is moved away from the slot so that drops of ink can pass through the slot.

摘要： A modular inkjet printhead assembly including a plurality of printhead modules mounted on alternating sides of a central rail assembly. The rail assembly includes a beam and a rod attached to a side of the beam. The printhead modules include a jetting module having an array of nozzles, a first alignment tab having a first alignment datum and a second alignment datum, a second alignment tab having a third alignment datum and a fourth alignment datum, a rotational alignment feature including a fifth alignment datum, and a cross-track alignment feature including a sixth alignment datum. Portions of the alignment tabs of the jetting module are adapted to fit within corresponding notches in the beam. Each alignment datum on the printhead modules engage with corresponding alignment features on the rail assembly to position the printhead modules such that the jetting modules are tilted away from the beam.

摘要： A modular inkjet printhead assembly including a plurality of printhead modules mounted on both sides of a central rail assembly. The rail assembly includes a beam and two parallel sets of rod segments attached to upstream and downstream edges of the beam. The printhead modules include a jetting module having an array of nozzles, a first alignment tab having a first alignment datum and a second alignment datum, a second alignment tab having a third alignment datum and a fourth alignment datum, a rotational alignment feature including a fifth alignment datum, and a cross-track alignment feature including a sixth alignment datum.

摘要： A gas flow duct for use in redirecting drops of liquid ejected from a printhead in a continuous inkjet printer, including a sump, a first duct portion upstream of the sump, and a second duct portion downstream of the sump. The first duct portion rises from an entrance to an apex and then turns downward and exits into the sump, and the second duct portion rises from the sump toward an exit port. A cross-sectional area of the first duct portion is adapted to produce a gas flow velocity sufficient to transport entrained liquid through the first duct portion past the apex and into the sump. A cross-sectional area of the second duct portion is larger than the cross-sectional area of the first duct portion and is adapted to produce a gas flow velocity insufficient to transport entrained liquid through the second duct portion.
