IR1600 bad copies on the front end

[buttalasso]

Hi everybody, I had seen the machine in object that has a problem on the copy: every page has the front side with a several irregular black lines. I've stopped the paper between the fuser and the drum and the defect was just in the drum.
I've checked the drum and the development, but I didn't seen anything abnormal.

I suppose that it could be the drum.

Is there anyone that could help me?

Thank you in advance

sounds like you already answered your question. These small machines the drum life isn't that long

23k copies is enough for a drum?

Look at the distance between the recurring marks. Create a cylinder that size in circumference, and it will usually lead you to the culprit. Also note that some developers seem to build up a deposit of toner that is deeper than the rest of the toner on the mag roller, and this will create recurring marks as well. Clean the mag roller off with a clean dry rag, and remove the toner buildup off of the mag roller...

Thank you everybody. The problem was fixed by the change of the drum
