Best Way to Connect Dampers to a CISS on the Epson XP-15000 (Nipple Conversion Guide)

Question: How can I connect dampers to a CISS when doing a nipple conversion on my Epson XP-15000? What parts and steps are required?

A customer asked how to properly attach dampers to a Continuous Ink Supply System (CISS) when planning a nipple-style manifold conversion on an Epson XP-15000. They also linked to the V3 Top-Load White Ink Dampers designed for nipple intake systems.

Answer

For your question regarding converting an Epson XP-15000 to use nipple-style dampers with a CISS, here is the most reliable and recommended process:

Understanding the Conversion

The XP-15000 originally uses standard clip-in dampers and a factory manifold. To use nipple-intake dampers-like the V3 top-load models you linked-you must replace the manifold entirely because the OEM version does not have nipple-style ports. These upgraded dampers are designed for direct tubing connection, which is ideal for CISS or DTF/DTG setups.

Required Steps and Components

1. Remove the Original Manifold

You will need to open the printhead assembly and remove the original manifold. This is the plastic ink distribution block attached to the bottom of the printhead.

2. Waterproof the Printhead Electronics

This is the most important step for long-term reliability in DTF/DTG conversions.

Inside the manifold housing are exposed electronic contacts and circuits. When switching to a damper and nipple system (especially if you will run white ink later), any micro-leak or condensation can cause shorts.

To protect these components:

• Use electronic-safe silicone sealant (RTV-neutral cure silicone is best).

• Coat the exposed internal electronics around the manifold mounting area.

• Allow it to fully cure before installing the new manifold.

This waterproofing step is essential, and skipping it is a leading cause of failed conversions.

3. Install the Nipple-Version Manifold

After waterproofing, replace the original manifold with a compatible nipple-intake manifold designed for your XP-15000.

This provides the ports required for the nipple dampers to slide on securely.

4. Attach Nipple-Style Dampers

Once the new manifold is installed:

• Push the V3 top-load dampers onto each nipple port.

• Ensure each one fits tightly with no wiggle.

• Prime dampers properly to remove air.

These are the dampers you referenced:

5. Connect the Dampers to the CISS Tanks

Once the dampers are mounted, simply connect:

• 3mm ID tubing → from the CISS tank outlets

• To the nipples on the dampers

In most cases, the following is needed:

• A CISS tank with individual outlet valves

• Soft silicone tubing

• Clamps (optional but recommended)

• Reset chips or chipless firmware (depending on your setup)

With everything sealed, the system becomes compatible with continuous ink feeding.

Important Notes

• This is a moderate to advanced modification.

• Waterproofing is critical for preventing printhead damage.

• If using white ink later, consider additional circulation/stirring.

• Always perform a pressure test before running the printer.

Addressing printer issues can be tricky because most solutions require hands-on adjustments and real-world testing. Because of this, we aren't able to offer remote troubleshooting or repair guidance. However, we do provide an in-person evaluation and repair service through our local diagnostic facility-details are available on our printer repair service page (https://bchtechnologies.com/printer-repair-service). Demand is high, so intake is on a first-come, first-served basis and may involve a waiting period. Our services allow repairs for whole printers or specific components with clear instructions, though they may not always be the most budget-friendly. For many users, self-help remains the best route. We recommend searching YouTube-including our own channel at BCH Technologies (https://youtube.com/@bchtechnologies)-using the search icon next to "About." With nine years of videos, even we can't recall them all, but YouTube's search will often suggest exactly what you need, including related content from other creators.
