If the transparencies have streaks, this could be due to condensed wax 
from the toner making its way onto the fuser assembly rollers during the 
fusing process. Try cleaning the fuser rollers using the following 
process:

1 Saturate a corner of a lint-free, static-free wipe with isopropyl 

alcohol.

2 Open the alternate path door (the small door) at the back of the 

printer.

3 Place the printer into calibration mode by opening and then closing 

the large door at the rear of the printer, or by pulling a drawer open, 
and then quickly closing it.

4 While the printer is calibrating, the fuser rollers are rolling. Place the 

wipe up against each roller in turn, keeping it in place for 5 to 10 
seconds.
