MFC 4550/6550MC/7550MC
OP-US-5.0
Maintenance
• Check
that
the
DOS
application
software
interface
settings
match
those
of
your
printer:
for
example,
if
you
are
using
a
parallel
printer
cable,
you
would
probably
set
your
DOS
software
printer
port
to
LPT1.
• Check
for
an
error
message
on
the
LCD.
• If
you
are
using
the
RS100M
serial
interface
board,
make
sure
the
RS-232C
serial
interface
is
selected
with
the
slide
switch.
Make
sure
the
interface
settings
are
correctly
set
up
with
the
proper
DIP
switches.
Make
sure
the
serial
parameters
for
baud
rates,
parity
and
stop
bits
match
those
in
your
application
software
and
the
MFC.
This
is
an
indication
that
your
application
printer
emulation
setting
and
the
MFC’S
printer
emulation
do
not
match.
Check
your
application
software
to
make
sure
you
selected
the
correct
printer
driver.
The
MFC
emulates
HP
LaserJet
IIP.
Try
setting
the
MFC
to
HP
emulation
in
Remote
Printer
Console
and
then
select
the
HP
LaserJet
IIP
printer
in
your
application
software.
This
is
common
problem
with
database
software
and
spreadsheet
software
when
they
are
not
correctly
set
up.
The
data
has
been
sent
to
the
printer
but
the
printer
did
not
receive
the
Page
Eject
command.
Press
the
FF/Cont
Key
to
eject
the
page.
Then
ask
your
software
supplier
how
to
add
a
Page
Eject
(or
Form
Feed)
command
to
the
end
of
your
job.
Use
the
Remote
Printer
Console
(RPC)
program.
Question
I
can
not
from
my
application
software.
The
MFC
prints,
but
it
prints
incorrect
information.
Sometimes
it
prints
a
couple
of
characters
and
then
ejects
the
page,
etc.
The
MFC
prints
the
first
part
of
my
document
but
does
not
the
last
page.
(The
LCD
shows
REMAINED DATA.)
How can I change the
User settings or default
settings on the MFC?
Recommendation
Question
I can not print from my
application software.
Recommendation
• Make sure you installed the Macintosh printer driver in the
System Folder and selected it with Chooser.
• Check the PORT selection within the Chooser: it should
match the port to which you physically attached the printer
cable.
• The serial slide switch on the optional interface board should
be in the Apple (RS-422A) position.
• Check the printer cable type: you can not use a LocalTalk
or straight-through cable. See Chapter 15 for details on
different types of printer cables.
