menu Test Print Function Yellow 20% Black 20% CMY 20% Gradation Toner Pallet Check Contamination Check Chapter 2 Operation of Diag. Description Outputs yellow 20% paint on the whole area of a A4 paper. When the PQ problem occurred, this test enables to identify the problem as the yellow toner or another color. Compare the sample chart (refer to 4.3.5) with the print. Check result: NG (Check the yellow toner-related.) OK (Check another toner.) Outputs black 20% paint on the whole area of a A4 paper. When the PQ problem occurred, this test enables to identify the problem as the black toner or another color. Compare the sample chart (refer to 4.3.5) with the print. Check result: NG (Check the black toner-related.) OK (Check another toner.) Outputs C/M/Y 20% paint on the whole area of a A4 paper. When the PQ problem occurred, this test enables to identify the problem as the balance of three color toners or otherwise. Compare the sample chart (refer to 4.3.5) with the print. Check result: NG (Check the C, M or Y toner-related.) OK (Check black toner.) Outputs the tone pattern from 2% to 100% on a A4 paper for each of 4 colors. When the PQ problem occurred, this test enables to identify the problem as the printing process or PWBA ESS-related. Compare the sample chart (refer to 4.3.6) with the print. Check result: NG (Check the printing process.) OK (Check the PWBA ESS-related.) Outputs each 100% density color pattern of Y/M/C/K. When the PQ problem occurred in the picture or photo printing, this test enables to identify the problem as the toner or another. Compare the sample chart (refer to 4.3.7) with the print. Check result: NG (Check the problem toner-related.) OK (Check the print job or print data.) Allows you to check the print for any regular lines or toner spots when encountering PQ problems. From the difference in the interval of regular lines or spots, you can determine the parts that have caused the trouble. Page 1 to 4: Prints the scale patterns in vertical and horizontal directions for evaluating regularity and intervals. (Refer to 4.3.8.) Page 5: Prints the list of intervals by component fault. 2 - 9
