3. Press Select. The printer automatically exits the operator panel
menus and prints the partial page.
Note: If the Print Buffer operation is selected while the printer is not
in the Waiting state, the printer automatically exits the operator panel
menus, but no page is printed.
Note: The system administrator can disable the Print Buffer function
by turning the Print Buffer Control setting Off. Print Buffer is not
displayed when Print Buffer Control is set to Off.

Activating Hex Trace Debug Mode

The Hex Trace menu function puts the printer in a mode that is used
to isolate print job problems. Each byte of information contained in
the job is printed in both hexadecimal and character formats.
Therefore, all emulation commands (PCL 5, PS 2, PJL, and so on)
are printed rather than processed, as is normally done.
To activate hex trace mode, select Hex Trace from the UTILITIES
MENU.
To exit hex trace mode, select Reset Printer from the JOB MENU or
turn the printer off.
