Half way into the printing some banding appears and it seams some printheads don't work. We exchanged 3 printheads, all tests and diagnostic images are excellent / then the printer works fine with 1 or 2 prints and they same is happening again. All cartridges ok all diagnostic ok. all aligned and cleaned numerous times. Now we don't know what else we can do.

Many thanks for any hints
