Epson surecolor S40 vertical banding

[datoshway]

Been having this issue with my S40 for a few months now more noticeable on vibrant colors. They are somewhat evenly spaced. I’ve tried heavy cleanings, manual cleaning, replaced the damper pad. Not sure what else’s could be going on. Any help is greatly appreciated!

It this all on the same roll of media or do you get it on others?
I can't say I've seen this happen on our S80 (yet) after ~5 years of printing.
Have you tried to run a media calibration? It should adjust both axes of print.

Check your heat settings. I just had a print come out looking like that on our s80 and it appeared to be because of a high heat setting + using overprints

If your pre-heat is too high for that type of media, and roller pressure is high as well, then it would cause this. Don't run pre-heat higher then 30, I run it off for some of my media's. Give that a try.

I would try a low pre-heat AND a high pre-heat. If the temperature and material are causing waviness, you should be able to see it laying just barely "not flat" as it comes onto the platen and can adjust accordingly.

Running something unidirectional would be another quick test if you're normally bidirectional and are fighting wavy material.
