Improving color copy To improve the color copy quality, this engine provides three types of adjustment methods: color adjustment, selecting the image reproduction method and its adjustment, and other adjustments. The color adjustment is performed by varying the level of pigments in RGB model or CMYK model, or by modifying the hue, saturation, and brightness of the image. To reproduce the copy image, select one of the two methods, the Dither (error diffusion) method or the Screen method. The Image Detection function helps in selecting the most appropriate method for each part of the original to make the copies of scanned image. For further improvement, use Copy Density or apply filters for Sharpness, Contrast, and Gloss mode. Note For detailed information about color adjustments, see the following subsections in the "Color Image Adjustment" section of the HP Color 9850mfp System Administrator Guide: Selecting density level and whitening background Changing color using RGB and HSB values (color adjustment) Changing colors using CMYK value (color balance adjustment) Selecting line screen, dot screen, or high compression (screen settings) Adjusting sharpness and contrast/selecting the gloss mode For detailed information about settings that can improve color, see the following subsections in the "Color Image Adjustment" section of the HP Color 9850mfp System Administrator Guide: Making adjustment in image detection (image judge) Specifying original type Using the scanning glass Use the scanner glass when the originals are not suitable for use with the document feeder, for example, when size is incompatible, or when originals are folded, stapled, torn, or generally in a poor condition. 1 Raise the document feeder. 2 Place original face down in the left rear corner.
