Have 1 in our office. Seems like the imaging unit just failed.
Also the transfer roller doesn't always get cleaned off.
attaching some samples.
It was also not adding black toner (did a motor test and you could hear a grinding type noise from the black unit. Like the auger was locked up or something).
I've added a toner holder with the motor on it and the tubing. The streaking was taking place before that then got way worse.
