Konica C550 Smudge Marks

[BrentV]

I am trying to print a newsletter on 11x17 doublesided glossy 80 lb xerox paper on a Konica Minolta C550. It has worked in the past but this time I am getting major smudge marks longwise on the paper. The smudge marks for the most part go the length of the paper and are varied in color but mostly black. They are not terrible dark but fairly light. Any suggestions other than some major replacements. I have about 150,000 total prints on this copier and it was bought brand new. Brent

Make sure you are setting the copier to the proper thick paper mode. You can also set the machine to quality, instead of speed for fuser settings in the tech mode. It sounds like you have toner not fusing to the paper and its transfering to the next sheet.

There was a guide sheet modification for this prob. prob happening coz of the static charge on paper guide (after transfer roller) atracting toner on it and comes on backside of the paper.
