Issues printing on Epson Display Trans with Epson 9900

[hacimd]

Has anyone else has had issues printing on the Display Trans II Backlight Media?  I'm getting getting banding in the dark areas of my print. I've ran nozzle checks and have been getting perfect test prints. I'm printing with a Epson 99900 printer, using matte black mode.  I'm using the most current ICC profiles- 'Display Media Backlight' and 'Display Media Backlight Plus'.  I have also tried using the 'Enhanced Matte Epson Profile'.  No luck so far, any other suggestions?  Thanks

Do you have high speed on? If so I would try one with it turned off. Does Display Trans Media require matte black? I usually print with glossy black on a Epson 7600.

To me, that does not appear to be banding. I would inspect the original file to see if those artifacts are there.

I assumed that I should print on this material using the matte black ink?  I didn't think to try printing using the photo black. I'll turn off the high speed and give it a try.

It might not be banding, but the artifacts are not found in the file.

It looks like head strikes to me. What media type settings have you got in place? Actual media type choice, media thickness, platen gap, suction level, etc...

+2.  It's head striking and the resultant temporary output issue.  If it's near the end of the roll, it could be media memory, too.

On the Canon iPF8400 you get those kind of results if the tension is incorrect.  Changing the head gap doesn't help.  I have no idea about the Epson 9900, but with the Canon large format printers when you create a custom media configuration there is a step where the printer will automatically test for the correct tension and embed that setting in the profile for the associated media.  If there is something similar for the Epson printers you might give that a try.
