In this video, I continue our DTF conversion series by showing you how to properly get ink into your printer, prime the ink lines, and fill the dampers without heavy modifications. This approach is ideal if you want to keep your printer as close to stock as possible while still running DTF ink reliably.

I’ll walk you through:

How to fill ink tanks using OEM bottles as funnels

How to identify and trim bottle tabs so one bottle works for all colors

How to verify smooth ink flow before connecting to the dampers

How to park the printhead correctly on the capping station

How to use the waste line and syringe to gently prime ink (with pressure control)

Why keeping pressure under 10 kPa matters

How pressure readings tell you if your capping station is sealing properly

When and why to run printhead cleaning (and when not to)

How to force ink into stubborn dampers safely using a syringe method

How to deal with air bubbles and confirm a fully filled damper

This process is not about fully filling the dampers all at once—it’s about helping the printer start correctly, clearing minor clogs, and making subsequent cleanings more effective.

I also explain:

Why clogged dampers behave differently

How to reuse EcoTank tubes instead of buying expensive model-specific tubing

What solid ink bars in the dampers actually indicate

If you’re new to DTF or struggling with ink not reaching the printhead, this video will save you time, ink, and frustration.
