摘要： A paper conveying apparatus which facilitates increased printing speed in a printer, such as a laser printer, by providing rollers which are rotated at different respective speeds at different times during a paper feeding and image transfer operation, so as to provide even feeding of the paper to an image transfer device. The paper is fed, one sheet at a time, relatively rapidly to the image transfer device, and at a slower speed, in synchronism with the image transfer operation, while transfer is being effected.

摘要： Systems and methods of mitigating the effects of crosstalk in an inkjet head. An inkjet head has ink channels that jet droplets of a liquid material using piezoelectric actuators. Drive waveforms provided to the piezoelectric actuators include jetting pulses that cause activation of the piezoelectric actuators to jet the droplets from the ink channels. When crosstalk exists between the ink channels of the inkjet head due to the piezoelectric actuators, the amplitude of the jetting pulses are modified to mitigate the crosstalk between the ink channels.

摘要： An electrophotographic printer of the transfer type with separate input bins for holding cut sheet print material and fan-fold form print material. Separate paper paths are provided from each bin to a first function. An input paper path is provided for moving either cut sheet or fan-fold forms from the first function to the transfer station. An output paper path is provided for moving either cut sheet or fan-fold forms from the transfer station through the fuser to a second function. Separate paper paths are provided from the second fuction to stack cut sheet material and fan-fold forms in separate output bins.

摘要： In a perfecting printing machine, a switch-back mechanism moves backwardly each sheet delivered out of the printing section, and a switching gate provided immediately after the switch-back mechanism selects a first sheet path to return the sheet whose one side has been printed to the printing section and a second sheet path so that the sheet whose both sides have been printed is delivered to the stacker after being moved backwardly by the switch-back mechanism.

摘要： Devices and method for performing temperature measurements in a printhead. In one embodiment, a printhead includes at least one row of jetting channels configured to jet droplets of a print fluid using piezoelectric actuators. A drive circuit includes an input voltage generator that applies a step voltage to a piezoelectric actuator of a jetting channel, and an output voltage detector that detects an output voltage across the piezoelectric actuator over time in response to the step voltage. The drive circuit also includes a temperature detector that determines a voltage response to the step voltage at the piezoelectric actuator based on the output voltage over time, and determines a temperature measurement for the piezoelectric actuator based on the voltage response of the piezoelectric actuator.

摘要： In a paper feed control system for a cut sheet-double side printing laser printer having a paper feed portion for stacking a plurality of paper sheets cut to a predetermined size; a paper feed mechanism for feeding the paper sheets one by one from the paper feed portion; a printing mechanism portion for printing first page data to one surface of the paper sheet, fed from the paper feed mechanism, by an electrophotographic means; and a return feed path which in order to print second page data to the other surface of the paper sheet, inverts the front and reverse surfaces of the paper sheet having the printed surface so as to selectively feed the paper sheet again to the printing mechanism portion. A plurality of feed roller mechanisms are provided which can be driven independently of one another so that the speeds of travel of a plurality of paper sheets in the feed path are changed independently of one another in accordance with the condition of the printer device or a host device.
