Adjustments Explanation When an image is stored in the e-Filing box in the full color or auto color mode of the scanning function (Scan to Box) and printed as it is (without setting the printing image mode), printing may be performed with image processing not suitable for the image, causing image quality that the user requires not to be obtained.
5. Scanning-specific Adjustments 5.1 To Clearly Scan Text (To reduce noise around text) Before the adjustment If the original is scanned in Full color mode or Gray scale mode, noise may occur in text or edges of a solid filled area. After the adjustment The image quality is maintained, while noise is being reduced.
5. Scanning-specific Adjustments (2) When scanning the original, press the [EDIT] button on the Control Panel. In the "RESOLUTION" option, select a higher resolution. * In the "RESOLUTION" option, "200 (dpi)" is selected by default. If noise occurs in a resolution of 200 dpi, select a higher resolution (300 dpi, 400 dpi or 600 dpi). After changing the resolution, scan the original and check the scanned-in image quality. If further adjustments are required, use procedure (1).
5. Scanning-specific Adjustments 5.2 To Scan the Original, while Eliminating the Background Color (To eliminate the background density) Before the adjustment The background color of the original is also scanned. Therefore, no clear contrast is made between the background and image. After the adjustment The background color is eliminated, allowing clear contrast between the background and image.
5. Scanning-specific Adjustments (2) Enter adjustment mode [05]. Change the values for codes [1070 to 1072] or [848] to decrease the background density. • The code to use varies, according to color mode (Full color mode or Gray scale mode). Adjust the value for the [05] code corresponding to color mode for which you would like to improve the image quality. Acceptable Color mode Original mode [05] code Value recommended Default value range Text 05-1070 Full color Set a value larger than 0.
5. Scanning-specific Adjustments 5.3 To Clearly Scan and Print the Original in Black and White (To improve gradation and reduce graininess) Before the adjustment After the adjustment If the original is scanned in Black mode, the halftones may become blurred in black. The halftones of the scanned-in image are clearly printed out. Explanation If an original is scanned in Black mode, a difference in the density level of the halftones cannot be accurately scanned.
5. Scanning-specific Adjustments Cautions after the completion of the adjustment The adjustment may possibly increase the size of the file to be stored. Therefore, carefully perform the adjustment, while checking the scanned-in image quality. The correlation between color mode and file size is as described below. (The ratio of the file size may vary, depending on the type of original. Therefore, use the description below just for your reference.
5. Scanning-specific Adjustments 5.4 To Scan the Original, while Reducing the File Size Before the adjustment After the adjustment Approx. 600 KB Approx. 100 KB Approx. 30 KB Approx. 200 KB Approx. 150 KB Approx. 900 KB Approx. 90 KB Approx. 550 KB * The above file sizes are just for your reference. * The above file sizes are just for your reference. If the original is constantly scanned at the default compression rate, the file size will become larger than required.
5. Scanning-specific Adjustments (1) When scanning the original, press the [EDIT] button on the Control Panel. Select a lower resolution option in the "RESOLUTION" option. * In the "RESOLUTION" option, "200 (dpi)" is selected by default. Select a lower resolution option (100 dpi or 150 dpi) to reduce the file size. * This adjustment will have an effect on the image scanned in all color modes (Full color, Gray scale, Black and Auto color).
5. Scanning-specific Adjustments Cautions after the completion of the adjustment • The table below shows you the correlation between the adjustment and file size. (The ratio of the file size may vary, depending on the type of original. Therefore, use the table below just for your reference.) • Correlation between a resolution and file size (procedure (1)) * The file size in a resolution of 200 dpi is 100%. Resolution File size ratio 200 dpi 100% 150 dpi Approx. 60% 100 dpi Approx.
5. Scanning-specific Adjustments Remarks • Use the following steps to change the default resolution, original mode, JPEG compression rate and/or background adjustment options: (a) Press the [USER FUNCTIONS] button on the Control Panel to enter the "User Functions" menu. (b) Press the [USER] button. (c) Press the [SCAN] button. (d) In the "RESOLUTION," "ORIGINAL MODE," "JPEG COMPRESS" and/or "BACKGROUND ADJUSTMENT" option, press the desired button to change the default.
5. Scanning-specific Adjustments 5.5 To Sharply Scan the Original (To increase the sharpness intensity) Before the adjustment After the adjustment The image looks too soft and blurred. The edges are enhanced. The image looks sharp. Explanation Adjust the sharpness intensity, in order to sharply scan the soft and blurred original. * This adjustment will have an effect on the image scanned in all color modes (Full color, Gray scale, Black and Auto color). 5.
5. Scanning-specific Adjustments Procedure * The adjustment is performed by the service technician only. (1) Enter adjustment mode [05]. Change the values for codes [1086 to 1088] and [840 to 843] to adjust the sharpness intensity. Color mode Black Full color Gray scale Original mode [05] code Text/Photo Text Photo Text Printed image Photo --- 05-840 05-841 05-842 05-1086 05-1087 05-1088 05-843 Value recommended Acceptable value range Default Set a value larger than 16.
5. Scanning-specific Adjustments 5.6 To Scan the Original, while Enhancing Black Before the adjustment Scan Black is not dark enough, compared to the original. After the adjustment Scan Black is enhanced and closely matched with the original hue. Explanation When a full-color original is scanned, black is not dark enough, compared to the original. (In general, the scanned-in image is likely to become less dark.
5. Scanning-specific Adjustments Procedure * The adjustment is performed by the service technician only. (1) Enter adjustment mode [05]. Change the values for codes [1075 to 1077] to adjust the black density of a scanned-in image. Color mode Full color Original mode [05] code Text Printed image Photo 05-1075 05-1076 05-1077 Value recommended Acceptable value range Default Set a value larger than 0. 0 to 4 0 * Setting "0" provides the lightest black, while setting "4" the darkest.
5. Scanning-specific Adjustments 5.7 To Scan the Original with the Desired Gradation Before the adjustment The image is scanned with natural gradation. (Default scanning) After the adjustment Gradation is decreased. After the adjustment Gradation is increased. Explanation When an original is scanned in Black mode or Gray scale mode, the reproducibility of halftones (gradation) can be adjusted by changing the scan density on an area basis (low-, medium- and high-density areas).
5. Scanning-specific Adjustments Procedure * The adjustment is performed by the service technician only. (1) Enter adjustment mode [05]. Change the values for codes [880 to 883] to adjust the gamma curve balance of the low-, medium- and high-density areas.
