What is the heck happened ? Magenta went crazy !

A poorly or not grounded head can print fine a lot of the time. The "echo" I'm talking about builds over time and once it hits a certain point, you start seeing stuff like this. Try Ordway Sign Supply in southern California. If it's available, they should be able to get it. Part number 1000006531.

Any reason why this would be magenta only ?

It appears, as you suspected, that the magenta, or light magenta, can't tell which without a nozzle test, is in a free fire mode. This is almost alway a ribbon cable issue. I would suggest you reseat both ends of all the trailing cables (from the mainboard to the carriage board) and all the head cables. Examine the position of each cable first to see if it is seated squarely in the connector, as this can help you see if that's the issue. Then, as you remove each cable, examine the traces on the end of each cable and look for any damage or corrosion, and clean if necessary by lightly burnishing with an eraser. Reseat carefully and squarely in the connector.

I did manage to fix the ( Ghosting issues ) by replaceing the longtail cables ! But now my issues is I'm missing my light Magenta channel completely , When I do a print test its completely gone ! I pulled ink from the cap top and did 2 cleaning and its still gone . I'm not sure where to go from here?


Changed board on top of head and its all good now.
