I tested by creating 5 solid color boxes: Yellow, Magenta, Cyan, Black, and a four color black made up of all 4 colors. When I print this test sheet, vertical white stripes appear in the magenta, black and 4 color black. when I print in grey scale none appear.
How can I fix this? do I need to replace a part? The usage menu says my K, C, M and Y drums are all just about ready to replace. Is it the drum or something else?
I suspect you created your colour blocks in Paint which does not give true colours. However the streaks will be certainly created by a worn out drum/s and as you say they are all near to being changed so that would confirm that. An expensive exercise awaits.
Drums.

What is the stats % of drums if low under 50% change them, soon as you add non Gen you throw a spanner in any attempt to fault find, fix is possible toner more than likely drum/drums, do a print of each colour and change drums as indicated by failure in its colour to print, check transport belt is OK and led heads are clean

Just replaced the color toner cartridges in the c5100N, two OKI (cyan and yellow) and one non-OKI (magenta). Now it appears that registration is completely off.
When printing an image, there is a band of yellow at the top about 6mm high, and a band of purple (not cyan) at the bottom about 6mm high. It seems that the yellow printing LED array is printing offset. I've verified this with a typical test page that shows yellow blipped up by several mm.
What the hell happened ? How can I fix it ?
Thanks -
Dean.

Drums are all at 34%. Please don't tell me that the drums only have a 50% lifetime on them, because that would just suck royally. When you say the problem is most likely drums, in what way ? What could have gone wrong ?
I was able to more or less fix the problem ... It took several iterations of ColorMenu->Adjust Registration followed by Maintenence Menu->Menu Reset, but it was finally able to pull the registration back into line.
I got worried at one point - after it was "fixed" the printer was powered off. Upon powerup again, registration was off by several centimeters ! Another round of the above finally "fixed" it again, but I haven't powered it down again.
It was a cheap printer. Maybe this is why ...

I was thinking about the band of yellow being caused by cleaning blade wearing on drum, drums are garenteed by oki if over 50 %, under that one is on their own ie purchase new if having problems with them
If you can fix problem doing colour calibration then faulty drum is not likely the issue.
Cant stress how many problems are caused by non gen consumables in machines, highly dont recommend their use.

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.
