Question:
I've been struggling with white ink clogs in my DTF printer and have tried different unclogging methods without much success. Is it worth replacing the printhead, or should I cut my losses and buy a new printer-possibly going with a CISS machine next time?
Answer:
Why White Ink Clogs Easily
White ink is notoriously more difficult to manage than CMYK inks. It contains heavier pigments (often titanium dioxide), which settle faster and tend to form blockages in the printhead nozzles. Without consistent circulation and regular use, clogs can build up quickly, sometimes leading to permanent damage in the printhead.
Repair vs. Replacement Considerations
-
Repairing Your Current Printer
-
In many cases, resolving this type of issue involves more than just the printhead. A technician may also need to service or replace the mainboard and cables that deliver signals to the head.
-
At BCH, for example, a mainboard repair typically costs around $75. On top of that, you would likely need a new printhead and cable.
-
If your model is something like the Epson ET-8550, there are ways to source a brand-new printhead, making repair a more viable option.

-
When Replacement Makes More Sense
-
If your printer model is older or parts are no longer available, replacing the unit may be the better financial decision.
-
Factoring in both the cost of parts and labor, repairs can sometimes approach or even exceed the cost of a new machine.
-
-
Considering a CISS (Continuous Ink Supply System) Machine
-
A CISS setup is designed to provide more stable ink delivery, and for DTF use, it can help maintain better ink flow.
-
However, even with a CISS system, white ink maintenance is unavoidable. You'll still need to agitate ink regularly, run scheduled cleanings, and possibly install circulation systems to minimize clogging.

Recommendation
If your printer model allows sourcing a brand-new OEM printhead and you are otherwise satisfied with the machine, repairing it could still be worthwhile. On the other hand, if your printhead is unavailable or the costs add up too close to buying a new unit, investing in a new printer (especially one designed for DTF with robust white ink management) may save you future headaches.
Addressing printer issues can be a complicated affair because of the hands-on nature of the problems. That's why we can't provide remote troubleshooting, suggestions, or detailed repair support. We do, however, offer an in-person evaluation and repair service (https://bchtechnologies.com/printer-repair-service). Due to high demand, our service is first-come, first-served, and it may take a few weeks before we can examine your printer. We can repair either the entire printer or specific components with clear instructions on how to proceed. That said, our rates are not always the most economical, so we also recommend exploring self-help options. A good place to start is our YouTube channel homepage (https://youtube.com/@bchtechnologies), where you can search for videos using the search function next to "About." This is the fastest way to find guidance, and YouTube may also suggest helpful videos from other creators.
Thank you again for contacting us. We truly appreciate your support and hope this explanation helps you weigh the decision between repairing your DTF printer or moving on to a new one.
