So it looks like samsung stopped making this laser printer toner (have this printer for years already always used original toner) cant find original anywhere online now so purchased a compatible toner which claimed to be good for this model number however after few days it started printing double, like if page has only three sentences on top and rest is blank it will partially show on bottom of page couple of lines that was printed on top, any ideas how to fix this? is it the toner causing this? Thanks
