Printing Both Sides of Paper (Optional
Duplexer)
The printer can automatically print on both sides of paper with an
optional duplex printing accessory (duplexer). This is called
duplexing. To order optional accessories, see page 9.
Note See the documentation included with the duplexer for complete
installation and setup instructions. Duplexing might require
additional memory (page C-1).
The duplexer supports sizes from 5.8 by 8.3 inches (148 by
210 mm) to 11.7 by 17 inches (297 by 432 mm).
Prepunched paper should be printed in a rotated direction for
2-sided printing (page 44).
