  • Publication number: 20080030534
    Abstract: A hand-held micro-fluid ejection device for manually ejecting fluid droplets onto a substrate during relative translational motion between the ejection device and a target area on the substrate. The ejection device includes a frequency generator to set a designated frequency signal for fluid droplet ejection by the device. The frequency generator is configured to operate open-loop with respect to the relative translational motion between the ejection device and the target area. An electronic processor uses the designated frequency signal to drive a micro-fluid ejection head that produces a predetermine droplet pattern. In some embodiments a manual tuner is provided to adjust the designated frequency. In some embodiments the designated frequency signal includes more than one component to control different elements of fluid being ejected.

  • Patent number: 7193380
    Abstract: A method for rotating a printer paper-feed roller wherein the roller is driven by a DC (direct current) motor. A feedback-control signal is applied to the motor until the roller reaches a desired rotational position. The feedback-control signal is a function of an error signal, and the error signal represents the difference between the actual rotational position and the desired rotational position of the roller. When the roller reaches the desired rotational position, the applied feedback-control signal is removed from the motor, and a direct-control biasing signal is applied to the motor to reduce or prevent rollback of the roller when the feedback-control signal is removed from the motor. In one example, the signals are PWM (pulse-width-modulated) signals.

  • Patent number: 7178914
    Abstract: A printer (1) in which a first sheet (5) to be imaged by printhead (3) is followed by a trailing media sheet. The first sheet is stopped intermittently so that the printhead can traverse the first sheet to print a partial image. The trailing media sheet is stopped behind the first sheet and is moved intermittently until it reaches or is near nip rollers (9a, 9b). Exit rollers 11a, 11b, 11c, and 11d move the first sheet out of the printer. When the exit rollers and the nip roller move forward and backward together the first sheet may be exited before the nip rollers are reversed to align the second sheet. Alternatively, the first sheet may be moved backward during alignment. The intermittent movement of the sheets may be at different times and with the trailing sheet moved less times and longer amounts than the first sheet is moved.

  • Patent number: 7121546
    Abstract: A speed mode for a printer (1) which has a pivotally mounted autocompensating system (19) mounted at an intermediate position in paper guide (17). That system (19) is driven by a motor (40) through a slip drive (70, 72, 74). The motor also drives paper feed system (15). When the motor turns in a direction to feed by system (15), the intermediate system is moved away from the paper guide. In basic operation, when a sheet (5) reaches a position to be fed by the intermediate system, the motor is reversed, and the intermediate system pivots against the paper for moving it further through the paper guide. In the speed mode the intermediate system is not employed and all of the feed is by the system at the tray. Since this will not feed shorter sheets, preferably the speed mode must be positively invoked, as by operator input or definitive information in the header of a print job.
