The 6515 can't do transparencies, in fact the 6515 is rather limited in what it supports, the official RML guide is only one page.
Glossy Cardstock or Labels would be the nearest thing in what is supported.
I am trying to print a flyer using the workcentre 6515. I am printing on doubled sided coated silk paper 150gsm and the printing is blotchy. Is this a setting problem or a paper problem or both?
My paper supllier has suggest this
Yes you really need to change the paper settings.
We have found that the 'transparent' setting can help, this feeds the paper through slower and not as hot.
It is usually just a setting with this paper.
How do I do that there isn't a transparent paper option
