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 print job.
Use the Remote Printer Console (RPC) program.
Question
I can not print 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 print 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.
