Printing on both sides (duplexing)
Guidelines for printing on both sides of the paper
See “Understanding specifications for supported media” for sizes and types of media
supported by the auto-duplex unit. For unsupported media types, print on both sides
manually.
Increasing the dry time may prevent ink smudges when printing on both sides.
For Windows, adjust the ink dry time by selecting Advanced Features from the Basics
tab in the printer driver.
For Macintosh, adjust the ink dry time by selecting the Ink tab in the Paper Type/Quality
panel.
For best results, do not print on paper heavier than 135 g/m
2
(36 lb bond), on both sides of
labels or transparencies, or on both sides of pages that are covered densely with ink.
Jams may occur when using these types of media for printing on both sides, and damage
to the printer may occur when printing on both sides of labels.
