Using MFP menus
PS SmartSwitch
Configures the MFP so it
automatically switches to
PostScript emulation when a print
job received through the USB port
requires it, regardless of the default
printer language.
On*
The MFP examines data on the USB
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 once
the menus are exited. 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.
USB Buffer
Configures the size of the USB input
buffer.
Note:
Changing the USB Buffer
menu item automatically resets the
MFP. Any permanent resources,
such as fonts or macros, are lost.
Disabled
Job buffering is disabled. Any jobs
already buffered on the hard disk are
printed before normal processing of
incoming jobs resumes.
Auto*
The MFP automatically calculates the
USB Buffer size (recommended
setting).
3K to maximum size
allowed
(1K increments)
The user specifies the USB 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 USB
Buffer size, disable or reduce the size
of the parallel, serial, and network
buffers.
Job Buffering
This menu item is shown only 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.
