HP LaserJet 4250/4350 Series - User Guide

Printing on both sides of paper (optional duplexer)

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.

NOTE

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.
