Conserve Toner

To help you conserve toner, your printer can simulate draft-quality printing. The amount of toner used during printing is reduced by screening the black dots in a 1:4.5 ratio. In other words, 1 black dot is printed for every 4.5 black dots that would in normal printing mode.

»Note: The Conserve Toner option is designed for draft printing only. Turn off the Conserve Toner option when printing proof or final copies of documents to avoid any possible distortion of patterns, halftone, and images. Unlike the control panel, PS Executive allows you to set Conserve Toner on a per-job basis.

Menu	Administration/Engine/Conserve Toner
Choices	On—Conserve toner; print draft-quality documents.
	Off—Don’t conserve toner; print normal, laser-quality
	documents.
Default	Off

Toner Out Action

You can configure the printer to stop when a TONER OUT error message is displayed in the message window or to continue printing.

Setting Energy Conservation

Your printer is compliant with US Environmental Protection Agency (EPA) Energy Star regulations. The EPA Energy Star Computers program promotes the use of energy-efficient personal computers, monitors, and printers and the reduction of air pollution caused by power generation.

»Note: The addition of some optional interfaces, in some combinations, may cause the product to become non-compliant.
