Black & White printing If you're printing drafts of a color document, or you're printing a color document that you want to photocopy, set Color Correction to Black & White in the Color Menu. Your document prints in shades of gray suitable for reviewing or photocopying on a monochrome copier. This preserves the toner in the magenta, cyan, and yellow toner cartridges. Printer Usage setting If print speed is not critical to you, you can set Printer Usage to Maximum Yield in the Setup Menu to extend the life of the color photoconductors and toner cartridges. If Maximum Yield is selected, the printer lowers the transport belt each time it detects a mono page (a page that requires only black toner). This allows the media to bypass the color print units as it travels through the paper path, thereby reducing wear. When the printer detects a page with color, it then elevates the transport belt and synchronizes all four print units. This adjustment may take up to 90 seconds, and thereby slows overall printing. The total effect this adjustment has on print speed depends on the mix of mono and color pages in the job, as well as the Timing Adjustment setting in the Setup Menu. See "Printing color and mono jobs" on page 63 for more information about the Printer Usage and Timing Adjustment settings. Conserving supplies 97
