In every DTF printer, the capping station is a crucial component. It is located at the bottom of the printhead and maintains contact with the printer’s nozzle via a spring mechanism.
During the printing process, when the printhead moves over the capping station, the pad is compressed, forming a completely sealed passage between the nozzle surface and the capping station’s rubber ring. This sealed passage is essential because it ensures that all ink and potential clogs are effectively cleared during printhead cleaning.
The lower end of the dtf capping station is connected to the waste ink pump. When the waste ink pump operates, it creates a suction force that quickly pulls ink out of the printhead, clearing any blockages in the nozzles. This process is vital for maintaining the cleanliness and proper functioning of the printhead, making the dtf capping an indispensable part of every DTF printer.
Comparing the Two Main Types of DTF Capping
There are two main types of capping station available on the market: Small Nozzle Plastic Capping and Large Nozzle Steel Mesh Capping. The primary differences between these two types lie in their size and material.
The Small Nozzle Plastic DTF Capping is sized to closely match the length of the printhead’s nozzles, which means that any misalignment due to imprecise assembly, thermal expansion, or mechanical vibration could lead to a leak in the sealed space, thereby affecting the effectiveness of the printhead cleaning.
On the other hand, the Large Nozzle Steel Mesh Capping Statio is about 2 millimeters larger in length and width compared to the small nozzle pad. This extra size ensures that even if the printhead or dtf capping is slightly misaligned, the larger pad can still fully cover the nozzles, maintaining the seal. This is one of the reasons why the large nozzle steel mesh dtf capping is more commonly recommended.
DTF Capping Compatibility with Different Printer Model
The compatibility of cappings is another important factor to consider. Currently, 4720 and 3200 printheads are widely used in most DTF printer, and both of these printheads can use the two types of dtf capping mentioned above.
However, the XP600 printhead has unique requirements and is not compatible with these cappings, requiring a specific pad instead.
Differences Between DTF Capping for Various Printheads
When choosing the right dtf capping for your DTF printer, it’s essential to consider the specific printhead model, as different printheads have varying requirements.
Below is a comparison of the dtf capping stations for the Epson TX800, XP600, and I3200 printheads:
| Feature | Epson TX800 Printhead | Epson XP600 Printhead | Epson I3200 Printhead |
|---|---|---|---|
| Sponge Size | Medium | Small | Large |
| Mounting Position | Standard mounting holes, specific to TX800 | Standard mounting holes, specific to XP600 | Custom mounting holes, designed for I3200 |
| Movement Mechanism | Push-pull mechanism | Push-pull mechanism | Lift (up-down) mechanism |
| Material | High-density foam | High-density foam | Advanced multi-layered foam with high absorbency |
| Material Compatibility | Compatible with standard materials | Compatible with standard materials | Compatible with a wide range of materials, including high-viscosity inks |
Key Takeaways:
- The Epson TX800 and XP600 printheads use similar high-density foam print head cappings with standard mounting holes and a push-pull mechanism. However, the XP600 uses a smaller sponge size, which may affect its capacity and cleaning efficiency.
- The Epson I3200 printhead, on the other hand, requires a larger sponge and uses advanced multi-layered foam with higher absorbency.
- This printhead is also designed with a custom lift (up-down) mechanism and mounting holes, making it compatible with a broader range of materials, including high-viscosity inks.
Common Issues with DTF Capping
DTF capping may encounter several common issues during use, which can affect their functionality. Thermal expansion and contraction, as well as mechanical vibration, can cause misalignment of the capping station or printhead carriage, leading to a poor seal.
The rubber ring of the dtf cappping may also suffer from aging or wear over time, impacting its sealing performance.
A particularly common issue during white ink printing is large areas of nozzles not ejecting ink when printing test strips. This problem is often related to an improper seal between the dtf capping and the printhead.
If the rubber ring of the dtf capping does not fully encompass the four rows of nozzles on the printhead surface, large areas of nozzles may fail to eject ink.
Typically, minor clogs present as thin lines (referred to as “broken needles”) can be resolved by cleaning the printhead or soaking it. However, if a large section fails to eject ink, such as 1/3 of a channel or a 1-centimeter-wide horizontal section, it is usually due to an air leak in the dtf capping.
How to Detect This Issue: After cleaning the capping, when the printhead comes back into contact with the wet capping station, observe the area around the nozzle surface to check for any traces of the capping’s rubber ring.
Ensure that the rubber ring completely encompasses the four rows of nozzles without pressing on the nozzles themselves. If the rubber ring presses on the nozzles, it can cause large sections of nozzles to fail to eject ink.
This type of clog is referred to as a “false clog,” meaning the printhead still ejects ink during printing, but the test strip shows that the nozzles cannot be cleaned properly.
How to Identify DTF Capping Issues
One simple way to identify capping issues is through tactile inspection. If you feel that the capping surface is no longer smooth or has tears or bumps, it may be a sign that the capping is damaged.
Additionally, if cleaning fluid poured onto the dtf capping fails to be absorbed and quickly leaks out, this indicates that the capping station may need to be replaced.
Cleaning and Maintenance of DTF Capping
To extend the life of an DTF capping, regular cleaning is essential. When the printhead is clogged, you can pour some cleaning solution, warm water, or purified water onto the capping station, and then place the printhead on the capping to soak (a process known as “soaking the printhead”).
If the dtf capping cannot retain the cleaning solution, it may be time to replace the capping.
How to Replace the Waste DTF Station: Epson I3200 Printhead Example
Regular replacement of the waste capping is crucial for maintaining optimal print quality and preventing ink overflow in your DTF printer. Below is a step-by-step guide on how to replace the waste dtf capping in an Epson I3200 printhead:
Step-by-Step Guide:
- Turn Off the Printer and Unplug It:
- Safety first. Ensure the printer is completely powered off and unplugged from any power source to avoid any electrical hazards.
- Access the Printhead Assembly:
- Open the printer cover to access the printhead assembly. Locate the I3200 printhead, which will be secured by custom mounting holes.
- Remove the Old Waste DTF Capping:
- Carefully locate the waste capping near the printhead. It should be connected to the waste ink pump via a tube. Gently disconnect the tube and remove the old dtf capping. Be mindful of any ink spillage, and use gloves to handle the capping station.
- Prepare the New DTF Capping:
- Take the new, large-sized capping made of advanced multi-layered foam, and ensure it is compatible with the I3200 printhead’s mounting mechanism. Check that the custom mounting holes align correctly.
- Install the New Capping:
- Secure the new capping into the mounting position, ensuring a snug fit. Reconnect the waste ink tube to the new pad.
- Reassemble the Printer:
- Once the new ink pad is in place, carefully reassemble the printhead assembly and close the printer cover.
- Run a Test Print:
- Plug the printer back in and turn it on. Run a test print to ensure the new dtf capping is functioning correctly and that the printhead is properly cleaned.
- Reset the DTF Capping Counter:
- If your printer has an capping counter, you may need to reset it after replacing the capping. This can typically be done through the printer’s maintenance settings or by using a specific reset tool.
By following these steps, you can ensure that your Epson I3200 printhead remains in top working condition, avoiding issues like ink overflow and maintaining optimal print quality.
