Actions 1. Repeat the scan or copy using a higher resolution (High or Max if scanning, Normal or Best if copying). You should also set background cleaning to 2, or set the content type to Mixed. You might also deactivate the automatic de-skew as explained in Copied or scanned image is very skewed on page 127. In case you were working in black-and-white mode, we recommend using grayscale instead. 2. If the problem persists, turn the original plot 90 degrees before scanning it again. 3. If the problem persists, clean and calibrate the scanner as indicated in Scanner maintenance on page 183. Inaccurately reproduced colors You have to deal with several variables if you want perfect color matching between the original you are scanning and the copy or scanned file you obtain as a result. If you find undesired colors in cases like the example shown below (original on the left, scanned image on the right), you can follow these guidelines. Actions 1. Make sure that you choose the correct paper type in the scan settings before scanning. 2. When dealing with copies, you must take into account that good color matching between a given original and its copy can be achieved only if both are printed on the same type of paper. In the case of scanned files, good color matching can be achieved only if your monitor is color-calibrated or compliant with sRGB or AdobeRGB standards. 3. If the above conditions are met, you should also take into account that various scanner settings can affect the final color result, such as contrast, background cleaning, content type and paper type. To obtain the best possible colors, set contrast and background cleaning to 0, set the content type to Image, and select the most appropriate type of paper according to the original you are scanning (if in doubt, use photo paper). 4. Note that the image enhancement settings are automatically reset to default values after a certain time, so you may get a different result from copying the same original if you have not checked the settings before starting the job. 5. If you scanned to a PDF file, try opening the PDF file in Adobe Acrobat and saving it as a PDF/A file.
