Ends up the not so reputable fellow that sold me the machine had converted all of the drums now color from black drums. I'm able to get the color drums to go with the black cartridge in though sometimes getting a t11 error. I posted in the FB riso forum and a kind person posted a pic of the board at the front of the drum set for color I checked the drums that I have and indeed they seem to be set for color though do not read the color cartridge and do read the black.
Below is pic set for color
Is that correct?
Any thoughts as to why it would not be working?
