Probable Causes
Solutions
Unsupported or incorrect paper.
Ensure that you are using the correct paper. For details, see Supported Paper
SIzes and Weights for Automatic 2-Sided Printing on page 40. Envelopes,
labels, transparencies, and paper heavier than 220 g/m² cannot be used for
2-sided printing.
Incorrect setting.
In the print driver Properties, select 2-Sided Print on the Paper/Output tab.
Check the settings at the printer control panel: Touch Printer > Tools >
Setup > Output Settings > 2-Sided Printing.
Date and Time Are Incorrect
The date and time are set automatically when the printer is connected to a network that has a Network
Time Protocol (NTP) server. NTP is used to synchronize the internal clocks of computers over a network
connection at system startup and every subsequent 24-hour period thereafter. This feature ensures that
the internal clock of the printer stays synchronized with the NTP server you specify.

Solutions

Change the Date and Time to Automatic by enabling NTP. Enable NTP using
