Message appears.
1. Make sure the DCP is on (plugged into the AC power outlet) and
turned the power switch on. and that it is connected directly to the
computer using the bundled IEEE-1284 bi-directional parallel cable.
The cable must not go through another peripheral device (such as a
Zip Drive, External CD-ROM Drive, or Switch box).
2. Make sure the DCP is not displaying an error message on the LCD
Display.
3. Make sure no other device drivers, which also communicate through
the parallel port, are running automatically when you boot up the
computer (such as, drivers for Zip Drives, External CD-ROM Drive,
etc.) Suggested areas to check: (Load=, Run=command lines in the
win.ini file or the Statup Group)
4. Check with you computer manufacturer to confirm that the computer’s
parallel port settings in the BIOS are set to support a bi-directional
machine; i.e. (Parallel Port Mode – ECP)
“MFC is Busy” Error Message
appears.
“MFC Connect Failure” If the DCP is not connected to your PC and you have loaded the Brother
software, the PC will show ‘MFC Connect Failure’ each time you restart
Windows®. You can ignore this message or you can turn it off as follows.
Double-click “\tool\WarnOFF.REG” from the supplied CD-ROM.
The Scan key on the DCP’s control panel will not work unless you restart
your PC with the DCP connected. To turn it back on, Double-click
“\tool\WarnON.REG” from the supplied CD-ROM.
Paper Handling Difficulties
The DCP does not load paper.
The LCD shows Check
Paper or Paper Jam.
Check to see if the Check Paper or Paper Jam message appears on
the LCD. If it is empty, load a new stack of paper into the paper tray. If
there is paper in the paper tray, make sure it is straight. If the paper is
curled, you should straighten it. Sometimes it is helpful to remove the
paper, turn the stack over and put it back into the paper tray. Reduce the
amount of paper in the paper tray, and then try again. Check that the
manual feed mode or MP tray or MP mode is not selected in the printer
driver.
The DCP does not feed paper
from the manual feed tray.
Reinsert the paper firmly, load one sheet at a time. Make sure that
manual feed mode or MP mode is selected in the printer driver.
How can I load envelopes? You can load envelopes from the manual feed or MP tray. Your
application software must be set up to print the envelope size you are
using. This is usually done in the Page Setup or Document Setup menu
of your software. Refer to your software application manual.
What paper can I use? You can use plain paper, envelopes, transparencies and labels that are
made for laser machines. (For information on paper you can use, see
Printer operation keys on page 6-16.)
How can I clear paper jams? See Paper jams on page 14-5.
