My printer was working fine using back feed for a borderless image to be printed on matte photo paper.  It stopped feeding - error message is that there is no paper.  

so, I want to feed from cassette.  I spsecified plain paper to get it to feed from cassette.  When I select borderless it auto sets it to back feed - which is not working.  

How can I get the back feed to work

or

how can I get the borderless print to print from paper in cassette?
