I'm not familiar with this model but have you ran the cleaning mode if it has one?

Replace the magenta image unit. Yellow image unit also and for the white streaks have the glass that cover the laser cleaned.

It might not be the rollers but the image drum. A bad image drum will sometimes cause streaks on print outs. If you look at the right side of the image drum you will probably see a streak that matches what is being left on your paper. Be careful not to touch the image drum as it will cause fingerprint on your printouts! Of course if the image drum is bad it will need replacing and fingerprints won't matter.

Remove all of your toners and clean them off. Replace each one and make sure they are well setted in the unit before going to the next one. Make sure the carosel turns smoothly and nothing is hanging up on the sides. Reboot the whole printer and let it settle for 5 mins before printing. toners come lose sometimes when you turn carosel around. Hope this helps you these printers are a ***** to deal with ,but when they are right there great.

Sounds like some of the magenta toner is left behind on the drum. The only way to fix it is to get a new cartridge.

I took the scanner apart. Then using a dampened eyeglass cleaning cloth, I gently cleaned the 3 internal mirrors.
No more yellow streak! :)

Streaks can be caused by a number of things
The fuser
The ETB
The toner cartridge
The firmware
The printer needs a cleaning.
The slot in the printer.
Incorrect Media.

Try cleaning the printer, use a lint-free cloth for the ETB, DO NOT touch the belt with your fingers, the oil from fingers will often make things worse.
Always use a lint-free cloth, if you ever encounter dirt inside the printer, dampen the cloth.

Calibrate the printer.
From the printer's control panel menu
Configure Device-> Print Quality-> Calibrate now.
