I'm running an Xante CL30, I've been having problems with the Yellow. Colors seem fine when printing spot colors, but when printing pictures they are heavy in the yellow channel. I have talked to Tech Support, we adjusted that channel down, no effect. Switch Image Led bar, No effect. New Drum, no effect. Replaced the High Voltage Power Supply, no effect. Has anyone ever seen this problem? And are there other repair options beside shipping to Mobile?
