    Pro C651ex speckling on itb transfers to non coated stock

    Replaced ITB and Bias roller, pm'd the ptr and cleaning station. There is a vast improvment in quality, but the speckling still remains. The specks can be seen on the itb itself...

    I spoke to a Canon color production tech and he says secondary transfer is to blame. What I need to know is how/where do I make adjustments to the secondary transfer setting. I understand you can make changes for each paper type in the paper library, but is there an sp to change it for the machine.

    If they are running off the paper library that will over ride any changes made in sp mode. You can make changes in advanced operator section of paper library. Also I'm only getting about 150k out of developer on these before they start to dump. I would look at changes those as well.
