We got a new SP540V about a month ago. Ever since, we've been having problems printing cyan, whether a gradient or a 100% C fill- we get long & thin areas where the color density drops out regardless of what media or profile used. We just sold our SP300, which has the same ink system & had zero problems during the entire 2 yrs of ownership. Roland techs are blaming everything you could imagine except the printer itself (I'm suspicious.) Anyone had this problem? If so, any resolution?
