Other Operator Panel Tasks The rest of this chapter contains examples of how to perform some other
common operator panel tasks. In addition, “Common Paper Handling Tasks”  on page 47 contains examples of how you can use the operator panel to
change Paper Menu settings, such as default media sizes and types. See
“Chapter 9. Configuring Printer Network Addresses” on page 185 for
information about how to set TCP/IP network values (IP address, gateway
address, subnet mask) from the operator panel. Making Duplex or Simplex Printing the Printer Default Situation: You want to set the printer default to either duplex (two-sided) or
simplex (one-sided) printing. Action:
1.   Press the Menu key until you see PAPER MENU in the display.
2.   Press the Item key until you see DUPLEX=ON or DUPLEX=OFF in the       display. An asterisk appears next to the current value. ON is the default
      value.
3.   Press the Value + or Value - key until you see the new value you want.
4.   Press the Enter key to select the new setting. An asterisk appears next to       the value, showing that it is active.
5.   To exit menu mode, press the Online key. Notes:
1.   Values set in print jobs (either by the print application or by the printer       driver) override values you set at the printer. If a print job specifies
      simplex printing and the printer default is duplex, the printer honors the
      print job setting and prints on one side only.
2.   The BINDING item on the Paper Menu lets you specify how you want       duplex jobs to print. If BINDING is set to LONG (the default value), the
      job prints as if the paper is to be bound along the long edge of the paper
      (on the left for portrait documents, along the top for landscape
      documents.) If you set BINDING to SHORT, the job prints as if the paper
      is to be bound along the short edge of the paper (on the top for portrait
      documents, on the left for landscape documents). The BINDING item is
      available only when DUPLEX is ON.
3.   Do not print duplex (two-sided) print jobs when the Face-up Output Bin is open. The Face-up Output Bin supports simplex (one-sided) jobs only.
Sending a duplex job when the Face-up Output Bin is open causes all jobs
to stop printing. Canceling a Print Job Situation 1: The printer is online and you want to cancel the job that is
currently printing. 26    Infoprint 21: User’s Guide
