    摘要: An inkjet printer system fires smaller ink droplets in a single-pass print mode to achieve addressible print resolution of 600 dpi in the carriage scan axis along with 300 dpi resolution in the media advance axis, without having to employ any dot-depletion algorithms. In one embodiment, the system provides a fast print mode which prints the smaller drops of ink on a 300 dpi grid in the carriage scan axis. In another embodiment, the system provides a single-pass color print mode wherein primary colors are printed with two color droplets of the same primary color in two adjacent sub-pixels on the 300.times.600 grid, and secondary colors are printed with two color droplets of different primary colors in two adjacent sub-pixels on the 300.times.600 grid.

    摘要: An inkjet printer has a pen holder for removably holding an ink pen, a detector circuit for detecting whether ink with a degraded quality is likely to be ejected by said ink pen, and a servicing circuit responsive to said detector circuit for causing an initial quantity of ink to be discharged from said ink pen to ensure that ink with a degraded quality will not be used during normal printing.

    摘要: A paper moving system for a computer driven printer/plotter comprises a paper pinching assembly positioned at the two oppositely facing edges of the paper adjacent the print zone 10. The edges of the paper are fed through each assembly where the paper is gripped between a lubricous shim plate 52 and a straight stretch of a paper drive belt 42 which frictionally engages the paper. The belts of each assembly are biased toward the shim plates by a spring urged rail 50 to hold the belts in non-slip engagement with the paper. The paper is tensioned edge to edge by the assemblies so that a paper table or platen underneath the print zone is unnecessary.

    摘要: A method for operating a thermal ink jet printer including a printhead having ink firing heater resistors responsive to pulses provided to the printhead. Warming voltage pulses are applied to the printhead to warm the printhead to a temperature that is at least as high as a temperature that would be produced pursuant to ink firing pulses of a predetermined voltage, a predetermined pulse width, and a predetermined pulse frequency. A continuous series of ink firing pulses are then applied to the printhead, starting with a pulse energy substantially equal to the predetermined reference pulse energy and a pulse frequency equal to the predetermined pulse frequency, and then incrementally decreasing the pulse energy of the ink firing pulses. The temperature of the printhead is repeatedly sampled while the ink firing pulses are applied to the ink firing resistors to produce a set of temperature samples respectively associated with the decreasing pulse energies. A thermal turn on energy is determined from the temperature samples, and the printhead is operated at a pulse energy that is greater than the thermal turn on energy and in a range that provides a desired print quality while avoiding premature failure of the heater resistors.
