Re: Cyan stripes on Kyocera TASKalfa 3050ci
Assuming that your document is A4 fed LEF, this is a classic cyan primary charge failure ... the interval will be 37.5mm (I had to do a little manipulating of the thumb sized image to figure out the approximate interval).
=^..^=If you'd like a serious answer to your request:
1) demonstrate that you've read the manual
2) demonstrate that you made some attempt to fix it.
3) if you're going to ask about jams include the jam code.
4) if you're going to ask about an error code include the error code.
5) You are the person onsite. Only you can make observations.

Re: Cyan stripes on Kyocera TASKalfa 3050ci
Yes. Easy. You'll need to remove the toner hopper:
-Open the front door, and remove the waste bottle and it's drawer.
-Remove the (4) toner cartridges.
-Remove the small chrome screw that lets you open up the shutter on the front of the hopper. This will reveal (4) Phillips plastic pieces. For each you press in, and rotate 1/4 turn to unlock. Careful! They break easily.
-Remove screw to open wiring cover, and unplug the hopper.
-Remove three screws in very deep wells.
-Release latches at far right and far left to lift off toner hopper assembly.
You can see the primary charge units now.
Re-assemble in the reverse. Be sure to re-lock those (4) plastic pieces on re-assembly or your waste toner will back up. Be sure to clear the cyan charge counter U930. A color calibration helps improve the copy quality but is not absolutely necessary.
Remember, on the older style primary charge units with a bunny brush type cleaner it's possible to clean the charge rollers with water or glass cleaner. Just make sure they are completely dry before re-installing. New style primary charge units with the helical foamy cleaner cannot be cleaned. If you do, you will get 1mm round dots at 37.5mm intervals. Never clean new style charge rollers.
Have fun. Let us know how you do. =^..^=If you'd like a serious answer to your request:

No need as BC pinned it down but you can swap around cyan drum unit with another one to isolate the fault.A tree is known by its fruit, a man by his deeds. A good deed is never lost, he who sows courtesy, reaps friendship, and he who plants kindness gathers love.

Re: Cyan stripes on Kyocera TASKalfa 3050ci
Hey guys!
This was fun, really - i liked it to work on this machine

The stripes are gone now, but i already ordered the primary charge as replacement because the cyan one i cleaned looked really bad:

Re: Cyan stripes on Kyocera TASKalfa 3050ci
yup utax is a 'rebrand'..
congrats.. you will learn and teach here... I know you will be a +!
curious HOW did you clean the primary charge? what cleaner/supplies/methods did you use? we might be able to give you some tips on the process.Comment

Re: Cyan stripes on Kyocera TASKalfa 3050ci
Yes, and UTAX is located only a few kilometers away from our company base
Thank you, i really appreciate it!
As blackcat said i cleaned it with some glass cleaner and after that with a small amount of water and lint free paper towels - then let it dry

Re: Cyan stripes on Kyocera TASKalfa 3050ci
Good job!
On heavy build up... try IPA and a small section of 'green scrubby pad' I cut one up in 1/2" squares and would use hemostats to hold scrubby pad.
Worked real well on corona wires.. but you had to be gentle.. or get used to stringing corona wire [emoji21][emoji23]

Re: Cyan stripes on Kyocera TASKalfa 3050ci
What happens is that the steel core of the charge roller rusts between the steel and the rubber coating. Then it arcs in that location, accelerating the rusting and consuming the rubber. If you were to cut into the roller you would see a hollow in the rubber, and a spot of rust on the steel core. Earlier versions of this charge roller would get radial arc marks ... like a spider with 12 legs ... then print that pattern onto every page at 37.5mm.

Re: Cyan stripes on Kyocera TASKalfa 3050ci
I would not try that on rubber rollers. You can damage the rubber outer 'skin'. What you did is the best that you can do on a dirty roller.
Do you mean the primary transfer belt (inside the main body of the machine), or the secondary transfer belt (on the door)? The primary transfer belt generally can remain untouched, paper dust is not an issue. The secondary transfer belt is also unaffected by paper dust, but you can watch that the belt remains centered on the pulleys, front to rear. There is a method of shimming the secondary transfer unit when installing a new one so that the belt remains centered. If the paper dust really bothers you you can use a Stretch-N-Dust or Swiffer (dust collecting cloth), but it will have no affect on the machine operation.

ONLY if they are old style charge units ... yes I clean them if I have the hopper unit off.
Do not clean new style charge units, only replace.
This is the difference:

I think the thing that I appreciate the most is that you've been doing some reading, and are using the industry terminology. I'll help everyone that makes a reasonable attempt.
It's gets difficult to understand when I get: "you know ... that black plastic thingy on the right ...", Everything on a copier is a black plastic thingy.
