We have recently bought a second hand OKI C5200 Colour Laser Printer and even though the black and white print seems to be great the clour is coming out with coloured streaks, what would you recommend?


One or more of the drums may be defective. Swap the black with another color and print a document. If that color printed the charectors ok, then continue the test with the other drums each taking a turn in the Black drum position until you find the bad drum.

Hi,

There are 3 parts to the imaging process that could cause your issue. You have the toner (x4), the imaging drum unit (Q3964A) and the fuser unit. If you are getting streaks from all colors, one or more these parts are the issue.

Let's start with the easy stuff:

Open the cover as if you were replacing toner where you can "visually" inspect the toner and imaging drum. Pull the drum out and pull back the "plastic shutter" on the top, this will expose a green drum CAUTION! Too much exposure to light and touching it can cause damage. Just take a quick look trying to see if any of the lines on your page match any marks on the drum. Check the bottom half of the unit as well there should be a white section across the bottom, expect that as well.

Next look at the toner, if you can look at any other color but black it will help you look for the streak marks a lot easeier. If you couldn't see any streaks on the drum on toner cartridges, it's time to look at the fuser unit. Power the machine down and turn it around, unplug it then fold down the blue clips and CAUTION! the fuser heats the toner to the page so if it's been used recently it may be hot. once the clips are down, just pull straight back and look for the streak marks.

Sorry for the book, but I hope it helps.

Internal test page fine, external prints black in blue


before you print, you have to check your options.

For example, if you want to print black and white, when you select PRINT from the menu, you click on PROPERTIES to the right side or bottom side, depending on which windows you use, then select grayscale/black and white, etc in the options that will follow to correctly use your ink, you can always REMOVE the ink from your printer as you only want to print black and white or non color pages.

I hope this helps you.

Vertical streaks


The toner forms small lumps and get stuck on the doctor blade of the cartridge. Where there are the lumps it blocks the toner from getting on the roller. Removing the doctor blade and cleaning it with a soft cloth and alcohol can solve your problem.
