Do DTF Capping Stations Need a Sponge Pad? Tips for InkSonic C13A, Procolored F8 & Prestige A3+ Printers

Question: I watched your video on keeping DTF printers running well, specifically for the InkSonic C13A, Procolored F8, and Prestige A3+. Do I need to have a little pad or sponge inside the capping station seal? Is that necessary?

Answer:

Do You Need a Sponge Inside the Capping Station?

In short, No, the sponge or pad inside the capping station is not necessary.

Let’s break this down for clarity:

What the Sponge (Pad) Does

Traditionally, many Epson-based printers come with a small foam sponge inside the capping station’s rubber seal. This pad helps to:

• Create a better seal against the printhead

• Soak up excess ink during head cleaning

• Keep the nozzle surface moist during idle periods

However, these pads also come with drawbacks, especially in DTF printing environments, where thick pigment inks are used:

• The sponge can become clogged with ink and dried residue over time

• It may block suction during cleaning

• It increases the risk of cross-contamination between colors

Modern Capping Station Designs

Many modern third-party DTF printers, like the InkSonic C13A, Procolored F8, and similar models, have started shipping without that sponge pad. Manufacturers realized that:

• A flat rubber seal often performs better and more consistently

• You can get a more complete vacuum during cleaning without sponge interference

• Maintenance becomes easier—less gunk to clean out

So if your capping station doesn't have a pad inside, that's normal. It may be intentional by design for better performance in DTF applications.

Can You Add One If You Want To?

Yes—if you still prefer to use a pad or your seal is missing something you believe was originally there, you can buy replacement sponge inserts for capping stations. They are available through Amazon, eBay, or printer parts suppliers. Just make sure:

• The sponge is ink-resistant and solvent-safe

• It fits snugly inside the capping cup without sticking out too far

• It doesn't interfere with vacuum pressure during pump operations

A Final Note on Printhead Health

Whether or not you're using a sponge, the most critical part of capping station maintenance is ensuring a tight, even seal and regular cleaning. If the capping station doesn’t seal properly, you’ll start seeing drying nozzles, ink starvation, or clogs, regardless of what’s inside the cup.

Repair Services & DIY Guidance

Handling DTF printer issues—especially around the capping station and ink delivery—often requires direct access to the printer. Due to the physical nature of these problems, we’re unable to provide remote troubleshooting or repair support.

However, we do offer in-person diagnostics and service through our printer repair center (https://bchtechnologies.com/printer-repair-service). Please note that availability is limited and services are provided on a first-come, first-served basis. It may take a few weeks before we’re able to evaluate your machine.

While our prices are not always the most budget-friendly, our services are thorough. That said, we strongly encourage customers to pursue self-help options first.
