When I print large banner after 1 or 2 yards my colors start fading and I get banding. If I pause machine and wait a minute everything goes back to normal. I am asuming this has to do something with dumpers. I have SC-545 EX. I saw on ebay people selling large dumpers. I am wondering if larger dumper will fix this issue. Did you guys tried larger dumpers? Or I am having problems with something else?
