Why do you need a Power supply? Neither codes deal with that. The 6751 is dealing with your scanner CCD which is located under the big glass on the right side that large black item. It could be bad or needs a alignment, the second deals with the Black image unit and or toner for black using 3rd party????? or OEM toners. Replace both he black image unit and black toner using OEM not 3rd party. As for jamming where does it jam? When was the last time the draw rollers where clean and or replaced? When was the last time the machine was cleaned, Gradation? and Registration? test done. Image units toned up? High end copier likes this needs to be keep up!!!!!
As for the imprints replace the FUSER UNIT (HOT PART) What color Ink bleeds replace that color image unit.
The CCD is bad raise the document feeder. under the big glass to your left is the CCD assy. Unless you know which screws to remove you remove the wrong ones and all your images will forever be messed up. so recommend a tech come out and replaced it. have open close the front door to reset the code
