‘Unable to write to LPT1’, ‘LP T1
already in use’ or ‘MFC is Busy’
error message appears.
Make sure that the machine is on (plugged into the electrical socket and the power
switch turned on) and that it is connected directly to the computer using the
IEEE-1284 bi-directional parallel cable. The cab le must not go through another
peripheral device (suc h as a Zip Drive, External CD-ROM D rive, or Switch box ).
Make sure that the LC D 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 comp uter manufacturer to confirm that the computer’s parall el
port settings in the BIOS are set to support a bi-directional machine; i.e. (Parallel
Port Mode – ECP)
Paper Handling Difficulties
Difficulties Suggestions
The machine does not lo ad 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 stra ight. 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 m ode is not selected in the printer dri ver.
If the LCD shows a Paper Jam message and you still have a problem, see Paper
jams on page 112.
The machine does not feed paper
from the MP tray.
Fan the paper well and put it back firmly.
Make sure that MP tray mode is chosen in the printer driv er.
I 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 applicati on. See your applic ation’s manual for
more information.
I need to know which pa per 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 11.)
There is a paper jam. See Paper jams on page 112.
Print Qualit y Difficulties
Difficulties Suggestions
Printed pages are cur led. Low qual ity thin or thick pa per or not printing o n the recommended side of the
paper could cause this problem. Try turning over the stack of paper in the paper
tray.
Make sure that you choose the Pape r Type that suits the media type you are
using. (See Acceptable paper and other media on page 11.)
Printed pages are smeared. The Paper Type setting may be incorrect for the type of print media you are using,
or the print media may be too thick or have a rough surface. (See Acceptable
paper and other media on page 11 and Basic tab in the Software User’s Guide on
the CD-ROM.)
