Xerox 6120 User Manual

Select paper with high opacity for duplex (2-sided) printing. Opacity refers to 
how effectively paper blocks out what is written on the opposite side of the 
page. If the paper has low opacity (high translucency), then the printed data 
from one side of the page will show through to the other side. Check your 
application for margin information. For best results, print a small quantity to 
make sure the opacity is acceptable.
Duplex (2-sided) printing can be done manually or can be done automatically 
with the duplex unit installed and enabled.

See “Media Specifications” on page 45. Duplexing envelopes, labels, 
transparencies, or glossy is not supported.

You should verify that the duplex unit is physically installed on the printer and 
enabled in the printer driver to successfully duplex the job.
Check your application to determine how to set your margins for 
duplex printing.
The following Binding Position settings are available:

In addition, if "Pages/Sheet" has been set to "Booklet", autoduplex printing is 
performed.

If "Short Edge" is selected, the pages will be laid out to flip 
at the top.

If "Long Edge" is selected, the pages will be laid out to flip 
at the sides.
