New 8570 here. Tried card stock four times. It jammed every time.
The jam was near the first of the rollers (I pulled tray 1 out and reached in and pulled the jammed card stock off the rollers, reinserted tray 1 and printing was OK except for card stock.
Can you tell me where I can make thickness adjustments?
I would advise you to read the Paper and Paper tray specifications
You must configure the paper tray for the specific paper type, weight and orientation
Additionally make sure the driver is as well configured accordingly to the printer.
Until the time one is not operating in the publishing company, then the possibilities of getting puzzled is high as a lot of choices of business cardstock are available in you need to.
