    Abstract: An ink tank security system on a printer includes an ink tank connection station having a cavity with a passage for insertion of at least one ink tank through the passage into the cavity to supply ink for printing operations by the printer and for removal of the ink tank through the passage from the cavity for replenishing with ink. A door is mounted adjacent to the passage for undergoing movement between displaced positions enabling or blocking movement of the ink tank through the passage to or from the cavity. A sensor adjacent to the door is adapted to sense movement of the door between the displaced positions. A security device separate from the ink tank is insertable into and removable from a control slot on the printer under the door to control re-use of the ink tank for replenishing the supply of ink.

    Abstract: A method of calculating at least a component of ink drop velocity in an ink jet printer includes jetting at least one first ink drop from a printhead firing plane. It is detected when the first ink drop is a first predetermined distance away from a reference plane. A first time period between the jetting and the detecting of the first ink drop is measured. At least one second ink drop is jetted from the printhead firing plane. It is detected when the second ink drop is a second predetermined distance away from the reference plane. A second time period between the jetting and the detecting of the second ink drop is measured. A difference between the first predetermined distance and the second predetermined distance is divided by a difference between the first time period and the second time period.
