Press Select ( ) to print the pages. The Print Quality Test Pages contain several pages. The first page, which is printed in English text only, contains a mixture of text and graphics. The information includes values of the Quality Menu settings in Settings and printer and toner cartridge configuration information. The remaining pages contain only graphics. For samples of the pages, see "Print quality test pages (Prt Quality Pgs)" on page 3-11. Color Trapping Uses an algorithm to compensate for mechanical incorrect registration in the printer. When small black text or fine black lines are being printed, the printer checks to see if they are being printed on top of a colored background. If so, rather than remove the color from beneath the black content, the printer leaves the color around the edge of the text or line. The hole in the colored region is reduced in size, which prevents the characteristic white gap that is caused by incorrect registration. Values include Off and numbers 1-5 (the default is 2). Values 1 through 5 indicate the amount of color remaining beneath the black content. Each setting increments by 1/600 of an inch. The more inaccurate the registration setting, the higher the setting needs to be adjusted. Selecting Off disables color trapping. 3-24 Service Manual
