| The printhead could be out of focus. Check to see if anything is bent where the printhead lowers down onto the drum. |

| To properly adjust the printhead you need to get the shims from KIP. They are very thin and do a fine tune adjustment. Good Luck. |

| I always adjust with the shims. When you start turning screws it is hard to get them back where they belong. |
