A:Answer Hello Leimamo. Paper can be loaded in the lower paper cassette of the WF-4820. Unfortunately, the printer does not have a rear paper feed specifically for thicker paper. However, the thickest paper supported is Epson Premium Photo Paper Glossy which weighs 79 lb. For cardstock, we recommend using paper that weighs around 44 lb, as similar Epson paper has been tested to work. You can try a cardstock that falls in that range, but your results can vary, as these recommendations are for Epson paper only. Regards, Syd - The Epson Team.
