‘Unable to write to LPT1’, ‘LPT1 
already in use’ or ‘MFC is Busy’ 
error message appears.

Make sure that the machine is on (plugged into the AC power outlet and the power 
switch turned on) and that it is connected directly to the computer using the 
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).

Make sure that the LCD does not show an error message.

Make sure no other device drivers, which also communicate through the parallel 
port, are running automatically when you turn on 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 Setup Group)

Check with your 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)

Suggestions

The machine does not load paper.

The LCD shows 

No Paper

 or a 

Paper Jam message. 

„

If there is no paper, 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 MP tray mode is not chosen in the printer driver.

„

If the LCD shows Paper Jam message and you still have a problem, see 

Paper jams

 on page 122.

The machine does not feed paper 
from the MP tray.

„

Fan the paper well and put it back in the tray firmly.

„

Make sure that MP tray mode is chosen in the printer driver.

Need to know how to load 
envelopes.

You can load envelopes from the MP tray. Your application 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 application. See your application’s manual for 
more information.

Need to know which paper is good 
to use.

You can use plain paper, recycled paper, envelopes, transparencies and labels 
that are made for laser machines. (For details, see 

Acceptable paper and other 

media

 on page 12.)

There is a paper jam.

See 

Paper jams

 on page 122.
