How to Convert a CISS System with Dampers and Printhead Holders for Epson Printers

Question:

I'm upgrading my CISS (Continuous Ink Supply System) from a setup by Highly Flavored to a new version. What dampers and printhead holders should I buy to make this conversion work?

Answer:

Understanding the Conversion: Mesh to Nipple System

From your description, it seems you’re transitioning from a mesh-type damper system to a “nipple” configuration, which is typically more reliable and serviceable. We carry a dedicated solution for this: the ET-8550 Printhead Upgrade Kit - PNC (Printhead Nipple Conversion)

This kit is designed for converting printheads to accept damper-style ink delivery, which is typically required when using external CISS systems or converting to bulk ink solutions. It replaces the mesh inlet system with nipple-style ports that connect directly to dampers or ink lines.

Damper Compatibility – Two Mounting Styles

Epson printers use two common styles for damper attachment to the printhead:

1. Cartridge-Type Attachment (Hook Style)

   • These dampers use a hook or latch mechanism similar to traditional ink cartridges.

   • They plug into a board located at the back of the printhead and may require a compatible head holder for secure installation.

2. Square Seal-Type Attachment (Around the Ink Intake)

   • This is a common setup for modified or advanced systems.

   • The V2 damper style

Depending on the mounting style your current CISS uses (from Highly Flavored), you’ll want to choose the appropriate damper type and printhead holder. If you're unsure, we suggest removing your existing dampers and checking how they interface with the printhead—either through a square seal or cartridge-style hook.

A Note on Printer Upgrades and Modifications

Upgrading to nipple-style dampers offers several benefits:

• Easier flushing and priming.

• Lower risk of air leaks.

• Better compatibility with aftermarket inks.

However, these conversions often require mechanical modifications and careful alignment. Be cautious to avoid damaging printhead contacts or causing ink starvation from improper damper seating.

Addressing printer issues can be a complicated affair due to the hands-on nature of the problems. So, we're not able to provide remote troubleshooting, suggestions, or support for printer repairs. We offer an in-person evaluation and repair service via our local diagnostic facility (https://bchtechnologies.com/printer-repair-service). Given the high demand, we operate on a first-come, first-served basis. So, it might take a few weeks before we can get your printer to drop it off. Our services are structured to repair either a whole printer or specific parts, with clear instructions on how to proceed. However, we acknowledge that our rates aren't the most economical. Thus, we highly recommend that you resort to self-help via online research. You can start by checking out YouTube or visiting our YouTube channel's homepage (https://youtube.com/@bchtechnologies). Look for specific videos using the search icon next to "About" on the right-hand side of the menu bar. I receive dozens of queries every day asking about videos for specific topics. Having created videos over the past nine years, it's challenging to remember every single one. Therefore, using YouTube's search function would be most efficient. Plus, YouTube might suggest relevant videos from other channels that could assist you.

Thank you again for reaching out and trusting us with your technical questions. Your commitment to upgrading and maintaining your printer is impressive, and we’re glad to support you on that journey!
