Hello all, what could be the cause for these vertical lines?

Call a trained technician for that machine, whatever it is.

Something having to do with the Cyan PCDU. Dirty shield glass or doctor blade.

Is there a laser slit glass cleaning tool inside the front door? Use it on all colors but concentrate mainly on cyan.

Thank you, this was it! It was something simple. I even took out the transfer belt which was unnecessary.
