Print speed is too slow. Try changing the printer driver setting. The highest resolution needs longer data
processing, sending and printing time. Try the other quality settings in the printer
driver Advanced tab. Also, click Color Settings, and make sure you uncheck
Color Enhancement.
Turn the borderless feature off. Borderless printing is slower than normal printing.

Color Enhancement is not working
correctly. If the image data is not full color in your application (such as 256 color), Color

Enhancement feature.
Photo paper does not feed
properly. When you print on Brother photo paper, make sure you always load one additional
sheet of photo paper first before loading the paper you want to print on.
Clean the paper pick - up roller. (See Cleaning the paper pick-up roller on page 89.)
Machine feeds multiple pages. Make sure the paper is loaded correctly in the paper tray. (See Loading paper and
other print media on page 9.)
Check that more than two types of paper are not loaded in the paper tray at any
one time.
Printed pages are not stacked
neatly. Make sure you are using the paper support flap. (See Loading paper and other
print media on page 9.)
Machine does not print from Adobe
