hp office jet pro 8710 not picking up cardstock

[AMSAFETY]

I bought this printer in April of this year (2016) and have been using it to print certificates on cardstock paper with no problems. All of a sudden my printer started printing off-centered as if it thinks the paper is two inches over. I have done the alignment and "clean printhead" option, I have also restarted, filled up the tray, fanned the papers out and opened the ink cartridge area to find absolutely no jammed paper. The same certificate will print perfectly on normal paper but now will not print on cardstock. (Weight of cardstock is only 176g/m3). NOTE: I have also tried printing on photo paper with the same off-centered result. Any help would be greatly appreciated!

The troubleshooting steps in the document here may help resolve card stock slipping in your Officejet Pro 8710 printer.  Clean the paper rollers as shown in step two and three of the section on "Printer does not pick up paper from input tray".

I cleaned the print head and was able to print 5 documents before it started printing off-centered again. Just did another round of cleaning and this time did the back rollers too, did a test print and it is still printing off. I am now trying the hard reset but seems like I may need to have it serviced.

I would not expect the hard reset to address this particular issue of the rollers not properly picking thick stock.  You can contact HP Support as described in Step 5 of the document I referenced above:
