Automatic 2-Sided Printing Problems 
 
Unsupported or incorrect paper. 
Ensure that you are using the correct paper. For details, see 
Supported Paper on page 44. Do not use envelopes, labels, reloaded 
paper, or paper heavier than 122 g/m² for automatic 2-sided 
printing. 
 
Note: Reloaded paper is paper previously printed or copied on laser 
or solid ink printers. 
In the print driver Properties, select 2-Sided Print on the 
Paper/Output tab. 
 
 
 
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. 
 
Note: To access this feature at the control panel, log in as an administrator.
