the nozzles of the printer might be clogged by dried inks thats why when your printing, its feeding the paper, as if its printing but no inks on the paper. print a nozzle check to see which part or color have clogs, if there are gaps or breaks, do head cleaning untill no more gaps then try printing.

type head and select "clean the print head nozzles"
