First page bad on 3070L Black issue.

[nullskull]

This 3070L is printing the first page/pages poorly. As pictured below the first page for both jobs are smudged with lines running parallel with the paper path. The lines also shift each time and are generally on the one side. The lines are gone either by the next page or more gradually. Usually 5 or so pages. I've cleaned the corona twice and the glass too. I was thinking it could be the drums but because it fades away after the first page I thought it might be something else. What should I look for? My plan was to swap drums next.

You can try swapping the black drum with one of the other colors to see if the problem stays with the drum

Most likely the lubricant has been used up and this compartment is filled with toner.

the lubricant for the transfer belt? Or what do you mean exactly?

I swapped drums and for now there appears to be no problems

[Ziggy]

I would order a drum to have on hand

Lubricant for drum of course.

Do you mean the white powder lubricant?

I've been working on KM production for years and have never had to lubricate the drum . If you ever use lubricate you use part number A50UPP0100 - Setting toner number 2. This is a special yellow toner designed for lubricating the transfer belt and transfer belt cleaner blade. Do not use the toner out of the bottle because it has a small amount of developer mixed with it .

What is the life count on the drum in question?

Good point.
Yellow toner for older models should be safe too as it has no developer powder in it. I mean C220 and such.

I mean this

I always replace the drums as a complete unit, never the parts inside of it when there's a specific problem related to a specific drum colour.

Same, that's why I ask the age of drum
