This is called banding.
1. Turn down the heat for the platen to 40 +-. this opens up the pores in the materal for the ink. front heater is to dry the ink. you will need to do a test print. You can play with the heat settings based on the material. do you have the banding on the built ion test print? if so it could be print head.
