The printer warranty does not cover damage caused by using refilled cartridges. 115 21 Conserving supplies Toner Saver To get the most from your toner supply, set Toner Saver On. This helps lower the cost of printing without greatly effecting print quality. Toner Saver can be used when color correction has been set to: Auto, 2-Color Draft, or Black and White. 2-Color Draft When you select 2-Color Draft, the printer only uses the black and cyan colors to print your document. This reduces the color toner applied to each page when you are printing multicolor drafts. This setting significantly cuts the cost of printing color drafts and increases print speed. Black and White 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 and White. Your document prints in shades of gray suitable for reviewing or photocopying on a monochrome copier. This saves the toner in the magenta, cyan, and yellow toner cartridges. The following illustration shows the difference for each of the three color correction settings. 116 Color correction setting Automatic 2 Color draft Black & white 117 22 Moving your printer Moving the printer If you're going to move the printer, you must remove the supplies and attached options to prevent damage to the printer.
