PVC Banner printing on HP Latex 365

Hello, We're trying to print a 5m PVC Banner, it starts ok but after about a metre it starts banding, we've tried 3 different types (all passed for latex use) and same results on all. We're just using the Generic PVC banner profile, tried adjusting the inter-pass delay, temperature and mode with no improvements. Printing fine on regular white vinyl and we've printing on the same material before with no problems. Any suggestions? Thanks

Hi @kingkahlua14364, First of all, check the Magenta yellow PHs. What is the PH status? Clean the PH with distilled water manually and install it again. Check if the Maintenance Cartridge is cleaning properly. Check the nozzles print status and if there are missing nozzles replace the PH. If all these do not fix the issue, I suggest contacting your support representative for advanced troubleshooting.
