    We're getting random clear (?) vertical lines, inboard/outboard on our iGen4. This does not happen during an entire run, just occasionally. In the offset world, I'd call it gear chatter but it's so random, I can't pinpoint it. It seems to happen on our photo-book runs - paper is 90# Mohawk Cover Navajo Smooth 13x26, 243gsm. Help?

    @CPMI you may want to check the contact arc on your fuser roll. As the machine runs the gap changes, so my educated guess would be making the adjustments to your fuser contact arc. 14mm-15mm

    I'm getting a 404 error on my side, so I can't see the photo.

    Can't get the image to upload so I added it as my profile pic. Right click to open in new tab. Hope that works. The pic defaults to horizontal but they are running vertically on machine.

    My guess would be, the wire module, in one of the colours, and not the fuser.
    If you have a PDF, where page 1 is black 50%, page 2 black 25%, page 3 magenta 50%, page 4 magenta 25% an so on with Cyan and Yellow.
    run the file and you can the see, which colour the lines appear in.
    Sorry for my english, hope you can get it :)

    I've seen it (in cyan with mine) where even a new wire mod may only get some of that banding down. My tech adjusted the donor roll speed (slowed it down I think) 'cause the rollers were causing too much vibration in the wires.

    hard to see in the profile pic....

    I agree... run sheets with separated colors to try and isolate it first.
