You need to pull the print head from the MFP and do some basic cleaning....Emujo

yeah man, toner and dev powder can lay on top of the PH. The cleaning wand may not move it all. Pull the IU's and shine your flashlight down through the slit that lets the PH unit hit the drum. Doing so will allow you to physically see if any debris is preventing the proper imaging. Did you replace or at least pull the transfer belt unit to see of maybe the cyan transfer roller is causing the problem? Good luck brother
