Description

What Is a DTF Printhead Cap Top?

The cap top (also called a capping station) is the part of a DTF printer that:

• Seals the printhead when it’s not in use

• Keeps the nozzles moist to prevent drying or clogging

• Sucks ink during cleaning cycles (through the pump)

It’s like a “garage” for the printhead — keeping it clean, lubricated, and protected.

🔧 Functions of the Cap Top:

1. Sealing the printhead to prevent air from drying out the nozzles.

2. Drawing ink during head cleaning using suction.

3. Helping maintain vacuum pressure so ink flows properly.

4. Preventing cross-contamination between ink colors.

🚨 When Should You Replace the Cap Top?

Signs it’s time to replace:

• Ink is not being drawn during cleaning

• Nozzle checks show missing lines despite cleanings

• Ink leakage or dried ink around the printhead

• You hear the pump running but no ink is moving

You should typically replace the cap top every 3–6 months, depending on use and ink type.

✅ Tips for Maintenance:

• Run head cleanings regularly, especially if the printer sits idle.

• Use proper DTF cleaning solution to flush the cap top.

• Always match the cap top size and type to your printhead model (e.g. Epson i3200, DX5, XP600, etc.).
