Printing on both sides of the paper (manual two-sided printing)
To print on both sides of the paper (manual two-sided printing), you must run the paper
through the printer twice. You can print using the top output bin or the straight-through
output door. Hewlett-Packard recommends that you use the top output bin for lightweight
paper and use the straight-through output path for any heavy media or media that curls
This feature is not supported in Mac OS X.
Manual two-sided printing can cause the printer to become dirty, reducing print quality. See
Cleaning the printer
for instructions if the printer becomes dirty.
