Abstract: A method for determining ink drop velocity of a printhead located at a gap above a print medium. A first ink mark is printed at a first printhead velocity. A second ink mark is printed at a different (in magnitude and/or direction) second printhead velocity. The ink for the second ink mark is ejected from the printhead at the same print ejection position used for the first ink mark plus an offset distance (if any). An optical scan of at least a portion of the print medium is generated using a non-printhead-carrier-mounted optical scanner. The distance between the ink marks is measured using the optical scan. The ink drop velocity is calculated using the measured distance, the offset distance, the first and second printhead velocities, and the gap.

Abstract: An inkjet printhead with nozzles 4 and liquid passages 31, 32 leading to each nozzle. The nozzles, ejection actuators 14, associated drive circuitry 22 and liquid passage 31, 32 being formed on and through a wafer 21 using lithographically masked etching technique, such that the wafer has a droplet ejection side and a liquid supply side. Each of the liquid passage is formed by etching a hole 31 partially through the wafer 21 from the droplet ejection side, and etching a passage from the liquid supply side of the wafer 21 to the hole 31. Etching a hole 31 into the wafer 21 from the droplet ejection side means the ink supply passage 32 can stop short of the interface between the dielectric 23 and the wafer 21 to prevent the etchant from tracking sideways and damaging the drive circuitry 22. As the inlet hole 31 is relatively shallow, the removal of the resist is not overly difficult. This allows the distance between the drive circuitry 22 and the inlet hole 31 to be reduced to less than 20 microns.
