SUGGESTIONS
Check the following:
• The MFC is plugged in and the power switch turned On. (See the
Quick Setup Guide on page 7.)
• The toner cartridge and drum unit are installed properly. (See
Replacing the drum unit on page 22-34.)
• The interface cable is securely connected between the MFC and
computer. (See the Quick Setup Guide.)
• Check to see if LCD is showing an error message. (See Error
messages on page 22-1.)
Reset the MFC or turn it off and then on again. Check the primary
settings in your application software to make sure it is set up to work with
your MFC.
Your computer is not recognizing the printer's input buffer full signal.
Please make sure to connect the MFC cable correctly.
Reduce the printing resolution. Reduce the complexity of your
document and try again. Reduce the graphic quality or the number of
font sizes within your application software.
Most laser printers have a restricted area that will not accept print.
Usually these are the first two lines and last two lines, leaves 62
printable lines. Adjust the top and bottom margins in your document to
allow for this.
Make sure the Brother TWAIN driver is selected as the primary source.
