Abstract: A liquid ejecting head of the present invention has a nozzle plate including a nozzle substrate composed of a non-conductive material in which nozzle openings pass through the nozzle substrate and a conductive film formed to cover at least a part of the inner peripheral wall surface of the nozzle opening. The film forming area where the conductive film is formed includes the moving range of a meniscus moving on the inner peripheral wall surface of the nozzle opening in accordance with the ejection operation of liquid drops from the nozzle opening. According to the present invention, even if a non-conductive nozzle plate is used, a charge can be injected smoothly into liquid drops without causing problems of deterioration of the image quality due to electrophoresis and of defective ejection due to foreign substances and gas generated by electrolysis.

Abstract: Xerographic machines can print documents that have unintentional streaking parallel to the process direction. There are many possible source of the streaking. Currently, the streaking is minimized by using a cross process direction dependent modulation, called a profile, to modulate a modulated light beam being scanned across the photoreceptor. The profile is purely a function of cross process direction position. The profile can minimize, and often eliminate, streaking for any one area coverage, but only for that one area coverage. Different profiles can be produced that work best for different area coverages. Choosing a profile from a group of profiles for use with each scan line can minimize parallel streaking for a wider range of area coverages.

Abstract: For a low saturation and high density region in a printed sheet identified based on rasterized data, flushing ejection is executed, with landing positions dispersed in the region. For a region being low in saturation but not high in density, an edge portion of the region is determined as landing positions. During these processes, adjustment is made to the ejection from inkjet nozzels for color components which are not to be subjected to the flushing ejection, to maintian the original hue of the region. This achieves the flushing ejection minimizing the degradation of the quality of the printed sheet. Further, in the variable printing, necessity of the flushing ejection is judged based on details to be printed on a base page. This causes the evacution of the flushing ejection whenever individual printed sheets are produced. Therefore, the print quality is held uniform during the production of different printed sheets.

Abstract: To prevent evaporation of the solvent in an ink from an ink supply tube and reduce the increase in the viscosity of color inks when a selected mode is switched to a facsimile mode, withdrawal-driving of pumps corresponding to the respective color inks is performed to withdraw the inks in the respective colors into ink cartridges from the respective ink supply tubes. Then, when performing color image recording in a printer mode again, color image recording is started by performing supply-driving of the pumps corresponding to the respective color inks to introduce the respective color inks into the ink supply tubes from the ink cartridges corresponding to the respective colors.

The handle is formed by two handle portions which fold from respective positions on either side of the gap to a cooperating position in which openings in each handle portion align to form a grip.

Abstract: Reflex writing is a group of algorithms developed to maintain color registration in xerographic systems using multiple imagers, in which sequential color separations are written based on events in the spatial domain. The imaging system includes a raster output scanner imager for the black station and a light emitting diode bar for the color station.

For each black scanline written the distance the belt travels is tracked using the simulated machine clock signal, and when the black latent image scanline has traveled the known distance between the two imagers, the light emitting diode scanline is written registered with respect to the raster output scanner scanline.
