DC250 white marks

[ihsaan]

I've been having trouble for a while with white marks down the side of my prints so today I tried to troubleshoot. Firstly I've replaced the black drum as the machine said "change charge corotron". and was hoping the marks would go away but it didnt. I've done the following so far in trying to troubleshoot:

1. Moved all the colour drums around
2. Cleaned the excess toner in the machine around the area where the drums are
3. Cleaned the fuser with a soft brush and cloth (did not open it)

But the problem still persists. The strange thing though is that when I print on bond paper the issue goes away and it prints 100%. It only happens on gloss. I've tried 130gsm. 200gsm and 300gsm are their respective media type setting. The 200gsm looks improved compared to the 128 and 300 but far from perfect.

Looks like the IBT either has some oil on it (from touching it) or the Fuser needs to be replaced. Try the later first.
