Banding Along Short Edge

[garethmrn]

Hi All,

Recently replaced a few items on a KM C3080 and am getting these issues, wondering if anyone has any ideas as to why?

Replaced Drums, Coronas and Transfer Belt /H

Any help would be appreciated.image005.jpgimage004.jpgimage003.jpgimage002.jpgimage001.jpg

No gradations of yellow?

The bands in the feed direction look like dirty primary charge coronas ... can't tell which from your images.

It would be helpful to have these images for diagnosis:

Its hard to tell what your problem is with these pictures. A description of the problem along with pictures would help

Have tried these but they don't seem to be showing the issue, I have scanned and attached them, also attached a scan of the Orange where it showing up quite a lot, they are darker bands about 2inches wide with a 5.5inch gap between, they are not fixed moved around sometimes, however some instance they are pretty much in the same place.

Definitely magenta drum. The interval for the drums is 188mm (5 1/2" + 2" = 7 1/2" = 190.4mm). You can also see it in the Henry Ford blue.

You should be able to swap drum locations and watch the color change. =^..^=

Run a test print 43 and that will print out a half tone and a full density of each color plus other colors . then you may be able to isolate it to one color.
