Using the MFP menus Serial Use these menu items to change printer settings affecting jobs sent to the MFP through an optional serial port. Menu item PCL SmartSwitch PS SmartSwitch NPA Mode Serial Buffer Purpose Values and descriptions Configures the MFP so it On* automatically switches to PCL emulation when a print job received Off through the serial port requires it, regardless of the default printer language. On-The MFP examines the data at the serial interface and selects PCL emulation if the data indicates that is the required printer language. Off-The MFP does not examine the incoming data. The MFP uses PostScript emulation to process the job if PS SmartSwitch is On, or uses the default printer language specified in the Setup Menu if PS SmartSwitch is Off. Configures the MFP so it On* automatically switches to PostScript emulation when a print job received Off through the serial port requires it, regardless of the default printer language. On-The MFP examines the data at the serial interface and selects PostScript emulation if the data indicates that is the required printer language. Off-The MFP does not examine the incoming data. The MFP uses PCL emulation to process the job if PCL SmartSwitch is On, or uses the default printer language specified in the Setup Menu if PCL SmartSwitch is Off. Specifies whether the MFP performs the special processing required for bidirectional communication, following the conventions defined in the Network Printing Alliance (NPA) Protocol. Note: Changing this menu item automatically resets the MFP. It is reset to configure memory, and any permanent resources, such as fonts or macros, are lost. On Off Auto* The MFP performs NPA processing. If data is not in NPA format, it is rejected as bad data. The MFP does not perform NPA processing. The MFP examines the data to determine the format and then processes it appropriately. 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 Auto* The MFP disables job buffering. Any jobs already buffered on the hard disk are printed before normal processing of incoming jobs resumes. 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. Network/Ports 40

Using the MFP menus
Serial <x>
Use these menu items to change printer settings affecting jobs sent to the MFP through an optional serial port.
Menu item
Purpose
Values and descriptions
PCL
SmartSwitch
Configures the MFP so it
automatically switches to PCL
emulation when a print job received
through the serial port requires it,
regardless of the default printer
language.
On*
Off
On–The MFP examines the data at
the serial interface and selects PCL
emulation if the data indicates that is
the required printer language.
Off–The MFP does not examine the
incoming data. The MFP uses
PostScript emulation to process the
job if PS SmartSwitch is On, or uses
the default printer language specified
in the
Setup Menu
if PS SmartSwitch
is Off.
PS SmartSwitch
Configures the MFP so it
automatically switches to PostScript
emulation when a print job received
through the serial port requires it,
regardless of the default printer
language.
On*
Off
On–The MFP examines the data at
the serial interface and selects
PostScript emulation if the data
indicates that is the required printer
language.
Off–The MFP does not examine the
incoming data. The MFP uses PCL
emulation to process the job if PCL
SmartSwitch is On, or uses the default
printer language specified in the
Setup
Menu
if PCL SmartSwitch is Off.
NPA Mode
Specifies whether the MFP
performs the special processing
required for bidirectional
communication, following the
conventions defined in the Network
Printing Alliance (NPA) Protocol.
Note:
Changing this menu item
automatically resets the MFP. It is
reset to configure memory, and any
permanent resources, such as fonts
or macros, are lost.
On
The MFP performs NPA processing. If
data is not in NPA format, it is rejected
as bad data.
Off
The MFP does not perform NPA
processing.
Auto*
The MFP examines the data to
determine the format and then
processes it appropriately.
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.
