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.
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 standard sizes from B5 JIS (7.2 by 10 inches
or 182 by 257 mm) to legal (8.5 by 14 inches or 216 by 356 mm).
Note The accessory dust cover cannot be used when the optional
duplexer is installed.
