11 Using the optional duplex unit

Duplexing your print jobs conserves supplies and reduces costs. To print a duplex job, select Duplex from your printer driver.

Note: To avoid paper jams when duplexing universal size jobs, make sure the paper size is between 148 mm–297 mm (5.8 in.–11.7 in.) wide and 148 mm–508 mm (5.8 in.– 20 in.) long.

Choose how you want your job duplexed: Long Edge or Short Edge. Long Edge means pages are bound along the long edge of the page (left edge for portrait, top edge for landscape).

Short Edge means the pages are bound along the short edge of the page.

Note: If you installed the optional duplex unit but are unable to select it from your printer driver, select the printer configuration or installed options tab in your printer driver and highlight the duplex option, which tells your computer the duplex option is installed.
