Printing on both sides of paper (optional duplexer) NOTE The printer can automatically print on both sides of paper when an automatic duplexer is installed. This is called duplexing. The duplexer supports the following paper sizes: letter, legal, executive, A4, A5, and JIS B5. The automatic duplexer is included with the HP LaserJet 4250dtn, 4250dtnsl, 4350dtn, and 4350dtnsl printers. For models that do not include an automatic duplexer, you can print on both sides manually. See To duplex manually. You can also order the duplexer as an accessory. See Ordering parts, accessories, and supplies. The duplex slot cover that is located at the rear of the printer must be removed when the duplexer is installed. See the documentation that is included with the duplexer for installation instructions. When duplexing very complex pages, additional memory might be required. See Printer memory. When the printer prints by using the duplexer, the page partially protrudes into the top output bin, and then reverses to print on the second side. 2 CAUTION 1 1 Duplexer installed 2 Duplexer removed Guidelines for printing on both sides of paper Orientation of paper for duplexing Layout options for printing on both sides of paper To duplex with the optional duplex-printing accessory To duplex manually Guidelines for printing on both sides of paper Do not print on both sides of labels, transparencies, envelopes, vellum, custom sizes, or paper heavier than 28 lb (105 g/m2) because jams or damage to the printer might occur.
