looks like you need to clean /replace carona wires and grid

[gregoryk]

make a hard stop before paper passes throught fuser i think you have fuser problem

as davidj7 said, first check cc assy, also clean ptretransfer corona in drum cartridge.

try to test print internal pattern to isolate problem.
if test print is with same problem, you have to concentrate
on xerographic process either on drum, developer, ibt or fuser.
