Using MFP menus
Serial Buffer Configures the size of the serial
input buffer.
Note: Changing the Serial Buffer
menu item automatically resets the
MFP. Any permanent resources,
such as fonts or macros, are lost.
Disabled The MFP disables job buffering. Any
jobs already buffered on the hard disk
are printed before normal processing
of incoming jobs resumes.
Auto* The MFP automatically calculates the
Serial Buffer size (recommended
setting).
3K to maximum
size allowed
(1K increments)
The user specifies the Serial Buffer
size. The maximum size depends on
the amount of memory in the MFP, the
size of the other link buffers, and
whether Resource Save is set to On or
Off. To maximize the range for the
Serial Buffer size, disable or reduce
the size of the parallel and USB
buffers.
Job Buffering This menu item only appears when
a formatted hard disk is installed.
Temporarily stores jobs on the MFP
hard disk before printing.
Note: Changing the Job Buffering
menu item automatically resets the
MFP. It is reset to configure memory,
and any permanent resources, such
as fonts or macros, are lost.
Off* Does not buffer print jobs to the hard
disk.
On Buffers print jobs to the hard disk.
Auto Buffers print jobs only if the MFP is
busy processing data from another
input port.
Serial Protocol Selects the hardware and software
handshaking values for the serial
interface.
DTR* Hardware handshaking.
DTR/DSR Hardware handshaking.
XON/XOFF Software handshaking.
XON/XOFF/DTR Combined hardware and software
handshaking.
XONXOFF/DTRDSR Combined hardware and software
handshaking.
Robust XON Determines whether the MFP
communicates availability to the
computer.
This menu item only applies to the
serial port if Serial Protocol is set to
XON/XOFF.
Off* The MFP waits to receive data from
the computer.
On The MFP sends a continuous stream
of XONs to the host computer to
indicate that the serial port is ready to
receive more data.
