I used my Epson 3810 to scan and print an article from a magazine, but the scanned print-out was so poor I couldn't read the text. So I tried to copy the article directly, but now the Epson 3810 won't function as a copy machine, nor will it print out anything from my computer. It will now only act as a scanner and will only print out scanned material. (With very poor quality!) What went wrong?
