I am currently working on hp laserjet 700 mfp m775 . The output shows unwanted mixed colors and bands .I changed the ITB ,Toner cartridges and updated the firmware to that effect but still problem persist. Since I initially suspected the DC controller I also disconnected all cables on DC Controller and reseated them back ,still no luck. Anyone here to assist please, though am considering replacing both ITB and DC controller. Attached is the output obtained from printer  .WhatsApp Image 2022-10-13 at 2.17.21 PM.jpegWhatsApp Image 2022-10-13 at 2.17.20 PM.jpeg
