espon c62

I have a espon c62 printer. My problem is the printer prints blank pages. I E. The printer goes through the motion of printing the paper is feed through but the end result is a blank sheet of paper. I have replaced both ink cartages, so I have ink. I receive no errors when printing. I have cleaned the printer heads, aligned the head via the program still prints blank sheets of paper. I have had the printer for about four months had now problems when I first connect it up.
