Installing Options Duplex Option Duplex Option Chapter 14 The duplex option enables the printer to print on both sides of the paper. The duplex option attaches under the printer, below the 250-sheet input tray and above any other drawers. The printer automatically recognizes that the duplex option has been installed. If you need to remove the duplex option, turn the printer off first. If you need to reinstall the duplex option, turn the printer off, reinstall, and turn the printer on. When the duplex option is installed, you can print either duplex pages or single-sided pages. See "Changing Duplex Settings" on page 278 for more information. For more information, see "Duplexing (Two-Sided Printing)" on page 152. Installing the Duplex Option If you are stacking several options, see "Adding Options to the Printer" on page 253 before you install the duplex option.
