This section lists some of the most common printer problems.

Check that the printer is connected to a working power outlet, 
turned on and ready (on line).

Check that the printer has plenty of paper. Some printers will not 
start printing when there are just two or three sheets of paper left in 
the tray.

Make sure the printer cable is firmly attached to the computer and 
the printer.

Run the printer’s self-test to check for any problem with the printer 
itself.

Make sure you installed the proper printer drivers as shown in 

 or in the instructions that came 

with the printer.

You may have connected the printer while the computer is on. 
Disable Sleep mode, turn off the computer, and turn off the printer. 
Turn the printer back on, make sure it is online, and then turn the 
computer back on.

Try printing another file. For example, you could create and attempt 
to print a short test file using Notepad. If a Notepad file prints 
correctly, the problem may be in your original file.

If you cannot resolve the problem, contact the printer’s 
manufacturer.

Many programs display information on the screen differently from 
the way they print it. See if your program has a print preview mode. 
This mode lets you see your work exactly as it will print. Contact 
the software manufacturer for more information.
