Hi,
You must replace the color drum cartridges (image unit ) as per video from http://www.support.xerox.com/support/phaser-7100/video/enus.html?contentId=122252.
Good luck!

I get strange stripes when printing color pages. If i print black/white everything looks good.
What needs to be cleaned or replaced? I already tried cleaning the laser lenses with the cleaning tool.
