Do these "blue lines" appear from every tray using portrait paper? Are the trays centered correctly?

Cyan iu failed.

Make sure to use the print head cleaning tool when you change an IU too, on ALL 4.

You should also do a gradation adjust, but 99.9% of customers give you a blank stare when you say that...

Also remove the carrier thats tracked from this failed iu off the tops of the ones to the right of it before it destroyes the drums in those too.

It's probably your cyan image unit. Time to get a new one. That is were I would start. And as mentioned me sure to use the cleaning tool to clean the print heads AND the lamps (if the print heads are at 6 o clock the lamps are at 5 o clock)
