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.

Based on my experience on toshiba models, is very fagile,do not simply touch unrelated parts,haha.
Anyhow, problem solved after replaced whole led unit, below is the problem led, nothing wrong with the k print head surface...

Interesting fault, I would appreciate if anyone has an explanation of how does the K drum was charged and LED ON to cause that line. Thanks for letting us know the fix.
Defects are simple, our mind is complicated
I think the faulty print head keep beaming/charging the drum causing the solid black line...This may be why the line stick on the 2nd transfer roller.
PS: Without the harness holding jig, we can tide up the connector & flat cable using tape, can be take out easily. But when install back the led unit, one person very hard to get it done since the hole not big, luckily customer willing to help pushing in the led unit while I get the connectors pass the hole
Yes disassembly takes a while but is not difficult. It really does take two persons to get the wiring routed back through the slots.
If I were to make a guess, I'd say that the circuitry that controls the black LED is turning ON a group of LEDs continuously. It's the only explanation. =^..^=

We have had a dead pixel on the LED array of one of these once but not a stuck on one.
The deformity presented itself during setup though.
