Hello paperjam,
I searched our knowledge base and found this article with trouble shooting step for blotchy or mottled prints. If you are still having issues after trying these steps, I suggest that you call into our support department for assistance @ 1-800-835-6100.
Sorry for the cryptic subject. I have a 6027 WorkCenter that has lately been printing rather rough on the right side of the print. Not sure how to describe it other than it's like someone took a clogged spray can of white paint and sprayed the right side of the print. Please see the attached photo. laskoemail@gmail.com. Any help is appreciated. Thank you.Messed up Prints
