If you mean the paper looks dirty, try a cleaner sheet. "Removes toner, dirt
and dust from the paper path to improve print quality."
I've still got a few sheets in a package opened Aug 1996. Switched to full
time color ink jet printers in 1997.
Seems to me that turning pages to print on the back was a problem along with
heat that curled the pages. No experience with recent laser printers. --
