CLX9201 Tint on white

[Allante666]

HI, CLX9201 has suddenly started printing a faint cyan background (evenly) on all colour prints and copies where it should be white (doesnt happen if in monotone). Changed Cyan toner cart (which was almost empty despite the machine saying 83% full- suspect may have been swapped prior to me seeing it) but has made no difference. Have run all the auto tone settings etc I can find (normally a canon guy so still finding my way round this one) but the tint still remains. Apparently started quite suddenly. transfer rollers etc all nice and clean as is the machine in general although it only does it in colour so Im ruling those out. Any ideas much appreciated!

Check the cleaning blade of the belt.

Check the cleaning blade of the belt.

I havent checked that but if it was the cleaning blade then surely it would do it with all colours not just the cyan?

It is not always true.
The 1.st step is to test the drum simply shifting it with another color. If the color of the background changes, you must replace the cyan drum after the repositioning.
The 2.nd step is to try to clean the cleaning blade group. You should see a quality improvement immediately after the cleaning. If it is the case you find the solution or one solution.

I already tried swapping the drum around but it still stayed the same colour background.
Also, it doesnt do it when it prints in black/white if that helps?

I will try cleaning the wiper blade though and see what happens. I seem to think the itb cleaner just slides out on this.

...it is the reason because I suggested you the check the cleaning blade of the belt.
I did have the same cases but not on this Multifunction: the problem was on the rollers of the developer group.

Cleaned the wiper blade but has made no difference unfortunately, all colour prints still have a light blue caste.

You have to empy from toner the ITB cleaning blade group, not simply "clean". Can you post a sample?

Yes sorry I should have made that clearer, I emptied and cleaned the whole blade assembly, the blade, the hopper, the screw.

Also, is there any way of checking the developer unit? Just spoke to a local tech who says it sounds liek the charge wire/roller. I can get one but dont want ot spend money on it if its not that.
