We are looking for someone that was some guidance on this issue. Everything, nozzle checks, clean encoder strip, clean wiper blade, perfect humidity) is passing the test but we are still having lines or banding in our dtf prints. We have been working with Ricoh but they are at a loss.

We also have that Service Manual available for download on the site

If the nozzle tests are good, and the banding only happens a few prints into the production run, then that indicates an possible damper issue, or ink flow issue of some sort.
Inspect the ink lines for air bubbles , or any signs of air contamination.
post some pics of the issue , and your nozzle test so we can take a look.
I have an Anajet MP5I here at the shop that is running beautifully, I jsut need a stepper motor for the maintenance station. There good systems, and the Ricoh heads are great.
I di have some spare used Ricoh heads if your interested, 1 was used for colors only not white, and might still be good. The has never had ink in it, and appears to be in good shape, was used for testing purposes only.
I'll send them BOTH to you for $200 plus shipping.
Kristi,
How many prints into the run are you getting before you start seeing the banding (1 shirt,2 shirts...etc?)
And what color is banding?
Can you post some pics?
