FS-C5025N blue streak on the edge

[spree]

Hi,
I have a problem with Kyocera FS-C5025N.
On the absolutely left edge there is a blue streak from upside down through whole page.
I removed blue toner, developer and tried to remove drum and I only little lift up the drum, after that the streak is only from first half of the page and dissapeaing to the left edge.
The tried drum cleaning mode and it doesnt helped.
Service manual saying it can be bad drum cleaning blade and to replace it, bad transfer unit or transfer cleaning unit, or try to clean corona charge wire.
Scanned example is here:

I will appreciate any suggestions.
Thanks.

the transfer belts come with new cleaning units. So it's probably best to change both of those at the same time. Another thing I always do anytime I get CQ issues on these is clean the LED print heads, and not by just running the little cleaning rod back and forth. I actually pop them out of the drum unit and clean them with alcohol. You'd be surprised how often that might be your problem on these machines.

I guessed it's a bad drum cleaning blade and I should to change drum unit.
Don't you give it much chance?

Being that you are getting a cyan streak, I would suspect the cyan drum unit.

A dirty print head should give you faded print for that color in a strip going from lead to trail edge.

A worn transfer belt would affect all colors.

A worn transfer belt cleaner would leave multicolor streak or grey streak.

And if it will be cyan developer it will be faded print also?
But that streak have really strong contrast on that page with all colors, so probably bad cleaning blade on cyan drum unit.

OK,
I tried to clean charge corona wire and it helped me, but after that the new problem has come - left side mainly on all colors is faded.
I then initialize developer refreshing and color calibration, but it won't help me.
Here are the two examples:

Take every thing back out and make sure they a seated properly when you replace them, also you can swap the drums around to see if the 1st fault is the drum. eg, move it to the magenta and if the line follows bingo! you know its the drum
