Samsung C8385ND printing quality

[thomfish]

Hi.

I have printing quality issue with Samsung C8385ND.
I printed Pattern 1 and attached it.
Can you help me identify the problem please?

As you can see from the picture it printed belts (wider lines) in various colors. I printed it again and the picture is the same (line in the same place)

I change

Imaging Units
Transfer Belt
Fuser.

Please help me solve this problem. What should I check? It seems to be very easy to identify the problem for technician.

I am sorry for my English.

I hope you can help me.

Thanks in advance

Please use any M C Y and Black test charts. RGB makes it a bit more difficult. Magenta has a problem, Black too. I don't know what else to suggest here.

Never apologise for communicating in another language. I can't speak yours and I think its awesome you put yourself out to get support.

Possibly this will help? The T2 roller T2 roller.pdf. At the least clean it with isopropyl alcohol?

Also check the laser light path.
We had an MFP here have a cricket crawl into the LSU and cause lines! Worth a check.

Hello

Problem has been solved. I removed LSU Unit and clean it. I found smears on the glass or path (not sure which word suit best).

Thank you Gazzahos for your suggestion.
