Hi. I have a Konica Minolta C350 Bizhub that will leave a blank strip
about 1/2" wide across the page (from top to bottom) at random when I
print. It will print fine without problems one time, then the next it
may print 70 pages fine and then leave blank strips on the next three
out of 10 pages. There seems to be no consistency on when it occurs
or where on the page it occurs. I've replaced the black imaging unit
and the image transfer belt, but it continues. Does anyone have any
suggestions on what is causing the problem.
