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.
Toner Out Action
You can configure the printer to stop when a TONER OUT error mes-
sage 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.
