mp 5500,mp6500,mp 7500 board question

[fshead]

hi
i have a down mp5500 with a sc672 that i just bought a complete controller unit"complete metal case all boards
and memory from someones parts machine.im told that this is interchangeable between all 3 models and mp6000 to mp8000.IS this correct?
just as an aside how is the mp5500 different vs the mp7500?
meaning if i put a set of mp7500 boards in a mp5500 is it a 75cpm machine?
thnx

SC 672 is usually a loose or dirty connection on the cable to the display panel. Depending on the machine model, it could also be the IPU board if the signal from the controller to the panel goes through the IPU.

thnx
i have had the control panel connector sc 672 code and got the machine running by pulling and cleaning connectors
but this one i feel is the control board..
i pretty much bought a whole set of boards from someone as i only have 2 mp6500 in the field..
I cant chance taking out a customers main copier,as i dont think they would be happy wth me..

I had a machine yesterday that I first thought was the control board. After swapping with another machine the problem did not move. Turned out to be the IPU board.

thnx..i have two full sets of boards making my way on monday..
when you get the 672 codes does your machine cycle up and warm up?
wasnt sure if anything can be deciphered by that..
trust me im hoping IPU brd as hytec wants big dollars to repair controller brd..
and advance exchange is almost $1000...............
always felt this model has some quirky things.

Operation panel on those models also goes through the VIB board located at the right end of the scanner assembly. That would be the first board to try as it is most likely the least expensive. It could also be the cable between the VIB and the operation panel.

If you do not have the birth certificate or a recent non-default print, clearing the NVram causes major headaches as it sets everything back to factory defaults before specifics for the laser unit and a few others have been done. Even with the BC or non-d, it is time consuming to reenter everything. As for the SC 555, it is a fusing error.

hi
thnx
i know the sc555 code,wasnt sure if the code carried over from the "donor" controller i swapped..
i usually power up wth door open,fuser puller out and top paper tray pulled just in case a wire is nicked or a staple
sitting inside..i usually scan the BC onto the document server but if the harddrive is toast i guess
i just lost it..the donor nvram from the same model,what outside of setting up the dev and drum,and web will
i have to reset or at least watch out for?
