Recommendation
• Turn the MFC on and off or reset it.
• Make sure your application software is correctly set up to use
the MFC by checking the printer settings in your application
software.
• Make sure that the correct interface type and settings are set
up to match your computer. Be sure to use the RS-422A serial
interface for Macintosh computers and the RS-232C serial
interface for PCs. Refer to “Connecting the Serial Interface
Board (RS100M)” in Chapter 15. (Only for MFC 6550MC/
7550MC)
The MFC received a very complex print job and could not process
part of the page. This may be solved by the following ways.
• If you are using Windows ® 95 or Windows ® 3.1 with the
supplied printer driver, see the “Windows ® Setup Printing
Problems” section.
• Try to reduce the complexity of your document or reduce the
print resolution.
This is a problem usually relating to serial interface settings.
Your computer is not recognizing the printer’s input buffer full
signal. Causes could be the wrong type of serial cable (incorrectly
wired or too long) or incorrect setting of your computer serial
interface.
• Expand the printer memory by installing one of the optional
memory boards (ME1000 or ME2000) .
• Reduce the printer resolution.
• Reduce the complexity of your document and try again.
• Reduce the graphic quality or the number of font sizes within
your application software.
Most laser printers have a restricted area that will not accept
print. Usually these are the first two lines and last two lines,
leaves 62 printable lines. Adjust the top and bottom margins in
your document to allow for this.
