Hi @printseychelles17062, If the ink supply is out of warranty we recommend that you change the light cyan ink supply and replace the printhead. If it is under warranty, please contact your support representative.

#1 Experiencing the exact same issue with LC printhead. Replacement lasted for one print and back to banding... If you figure it out let me know!

We have had this issue in the past. If you know how, trying aligning the primer. It has worked for us.
