Menu Item Values and Functions of the Menu Items
Serial Buffer Disabled
Auto*
3K to maximum size allowed
Your printer has a variable buffer size that can be changed from the
operator panel. You can configure the size of the input port buffers to meet
your system needs. The maximum size available for modification depends
on the amount of memory in your printer, the size of the other link buffers,
and if the Resource Save setting is On or Off. To maximize the range for
the Serial Buffer size, you can disable or reduce the size of the parallel,
network, Infrared, Fax, and LocalTalk buffers. The Auto setting indicates
the printer selects the buffer size based on the total memory available.
Changing the Serial Buffer setting automatically resets the printer.
Job Buffering Off*
On
The Job Buffering menu item does not display if the formatted hard disk
is defective, is Read/Write or Write protected, or if the Job Buffer Size is set
to Disabled. 61 Defective Disk displays during printer power on. See 61
Defective Disk on page 189 for more information. Also, see Job Buffer Size
on page 93.
Job buffering lets you delay processing of a print job. The job is temporarily
stored on an optional hard disk before being printed. This usually frees the
host computer during the actual printing of a print job.
If Job Buffering is set On, print jobs are buffered to the hard disk. If Job
Buffering is set Off, the print jobs are not buffered.
Changing the Job Buffering setting automatically resets the printer.

RS-422 Polarity Normal*

If you select RS-422 for the serial communication configuration, you can
then select Normal or Reverse polarity.
