Had MPC3300 at a customers today that was not laying any Yellow toner onto the prints. I was fortuanate that the customer had a few of this model on site to swap parts and i found the bias wire for the Yellow itb transfer roller had corroded and snapped. Just thought i would pass this on as it might save someone spending on a complete itb assy. I have enclosed pics and have pulled the wire further away for clear pictures but initially it did not look to be a broken wire until i pushed it with my finger.
