If you are having difficulty with your machine
If you think there is a problem with your MFC or the way your faxes
look, make a copy first. If the copy looks good, the problem is
probably not your MFC. Check the chart below and follow the
troubleshooting tips.

Printing or Receiving Faxes
Condensed print and white
streaks across the page or the

can make a copy using the Black Start key to see if the same problem
occurs. If the copy looks bad, call Brother Customer Service at
