Purchased Envy Photo 7155 since it had a tray for 4x6 size. Went to put in card stock in top tray which indicates 4x6 and will not accept for printing. It tells me to load paper in the tray. It is in the tray.
It is possible, though again assumed, that the photo tray is ONLY to be used for photo paper. This sounds silly - your Index paper is the same size. Nonetheless, if the photo tray can sense photo paper and it does not like Not-photo paper, you cannot just fool the printer.
What to do?
Remove other paper from main tray, load Index card paper into the main tray, snug the bars to the sides, set the type/size on the printer control panel and in your printing software / application.
