Visual check for errors while printing the diagnostic sheet Once the diagnostic plot is printed, the first step is to check that all the patterns included in it are correctly printed. The diagnostic plot, if printed correctly, should look like this: If you see any problems, you should follow the recommended recovery procedure, all of which are available by tapping , then Image-quality maintenance at the front panel. Once the printer has been diagnosed and it is working correctly, you can reprint the diagnostic plot as described in Scanner diagnostic plot on page 130. Scan or copy the diagnostic plot There are two options for evaluating the diagnostic plot: scanning into a JPEG file, or copying onto paper. We recommend using the scan option, so that the generated file can be analyzed more easily by a remote support engineer if necessary. If you decide to scan the plot, first adjust your computer's monitor as described in Monitor calibration on page 132. Once you have scanned the diagnostic plot, remember to open the scanned file in any image viewer software and select a zoom of 100% for correct visual evaluation of patterns. If you decide to copy, make sure that a paper roll at least 36 in (914 mm) wide is loaded in the printer. Ideally, the same type of paper used to print the diagnostic plot should be used for copying it. These are the settings that you should select: Scan ● Quality: Max ● File type: JPG ● Content type: Image ● Compression: medium ● Paper type: photo or matte, according to the paper used to print the diagnostic plot. Use photo if in doubt. Copy ● Quality: Best ● Content type: Image ● Paper type: photo or matte, according to the paper used to print the diagnostic plot. Use photo if in doubt.
