5.7.5 How to Update the Print Positioning Parameter
I think that might be what you need to do. The Black is not fiing at the correct position.
Or perhaps the CW and CCW Alignment, But I'd try the print position first.
Ditto. this will align your black with your color heads. Them you need to tweek the print position parameter so that there is not any white gap between the color and black. There are not any set parameters for the printer you just make small adjustments in them until they line up. Each printer can be different slightly.Hi. based on you test print you need to set the head tilt before doing any thing else. the color and the black heads are not lined up. see page 125 5.4.5 to set head tilt . you must follow the set up step by step.
