We have an almost new Canon IR 2535 at a customer's site with a bolded/blurred text that shows up in one area only on the second side of the copy when duplexing. We've seen something similar on a new machines just out of the box with the bolded/blurred area in a different area of the copy (different pattern too) only this time it has occurred on the 1st side of the copy when even just doing a Test Page Print. We've tried different paper and sometimes it helps and sometimes not. With winter starting to melt some snow, the humidity has slightly increased and that also seems to help, but the problem is still there. Has anyone had this problem and if so, do you have a final fix for it as we have talked with numerous techs. and no one has come up with a solution. Please see attachments.
