Hi- I have an MF8170c. The green "recv'd in memory" indicator is lit and I know there are documents que'ed that are waiting to print. I changed a printer cartridge that was I was being prompted to change but still no printing. When I unglug and repower the machine, it prints a horizontally patterned page that looks like linen, with 3 red and 3 green cirles in the upper right third of the page. This is an emergency as I have an out of country meeting that I am leaving for tomorrow and 45 or so pages of docs that need prinitng...HELP PLEASE!! Thanks
