Hello anmc1974,
I searched the Support page and found this article that may help you with this issue.
I have blank birthday cards on mild gloss cards that are smearing ink.
I have tried different settings on cardstock and all others. I have bought non gloss cards and it still smears.
The problem isn't from printing directly rom the computer as I have tried that, and then tried to print from a copy, the result is the same. Can anyone advise what I can do?
