    摘要： Electromigration within heater resistors of printheads is prevented by taking into account a resistance degradation characteristic of the heater resistors. In one method a burn in operation of the printhead heater resistors is provided in order to bring the heater resistor resistance to a substantially stable resistance value. Alternatively, a method of controlling firing of a heater resistor within a printhead of an ink jet printer involves establishing a desired current density or maximum acceptable current density for the heater resistor. A resistance of the heater resistor is thereafter monitored during printing operations. Based at least in part upon the monitored resistance, a firing voltage across the heater resistor is adjusted in order to maintain the desired current density through the heater resistor or in order to hold current density through the heater resistor at or below the maximum acceptable current density.

    摘要： 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.

    摘要： A toy mailbox for children includes a storage unit and a media processing mechanism. The storage unit includes a door member for closeably opening the storage unit and an ejection slot configured on a portion of the storage unit. The media processing mechanism is coupled to the storage unit, such that the media processing mechanism is capable of dispensing a media sheet having data content printed thereon, into the storage unit through the ejection slot. Opening the storage unit enables children to access the media sheet from within the storage unit. The media processing mechanism is also capable of printing the data content on the media sheet prior to dispensing the media sheet into the storage unit.
