CHAPTER 6 TROUBLESHOOTING
CHAPTER 6 –11
Printing
Question Recommendation
The printer prints unexpectedly
or it prints garbage.
•
Turn on and off the printer or reset the printer.
•
Make sure your application software is correctly set
up to use this printer by checking the printer
settings in your application software.
•
Check the printer emulation settings. If you can use
the supplied RPC program, use it to change the
settings as required. Also, you can print the current
setting list from the RPC program or Printer
Control Panel. (For HL-730/730Plus series Only)
•
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
in Chapter 4. (For HL-730/730Plus
The printer cannot print full
pages of a document. An error
message “Print Overrun”
occurs.
The printer 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 “Setting up the
Printer for Windows” section.
•
Try to reduce the complexity of your document or
reduce the print resolution.
The printer prints the first
couple of pages correctly, then
some pages have text missing.
(For HL-730/730Plus series
Only)
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 incorrect
serial cable (incorrectly wired or too long) or incorrect
setting of your computer serial interface.
The printer cannot print full
pages of a document. A
"Memory Full" error message
occurs.
(For HL-730/730Plus series
Only)
•
Expand the printer memory by installing one of the
optional memory boards.
•
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.
My headers or footers appear
when I view my document on
screen but do not show up when
I print them.
Most laser printers have a restricted area that cannot be
printed on. Usually the first two lines and last two lines
of text cannot print (leaving 62 printable lines). Adjust
the top and bottom margins in your document to allow
for this.
