- FIX THESE GTX PROBLEMS FAST:
- Random dropouts despite normal test prints
- Air in white ink tubes that won’t go away
- Ink not flowing after head replacement
- White ink circulation failure
It was working fine in the morning, but suddenly white ink stops printing - Air begins to enter the tubes
- No improvement even after cleaning
- Upper tubes backflow or air cannot be cleared
- White ink becomes extremely faint or patchy
👉 In many cases, the cause is air lock or poor ink circulation
■ Print Quality Issues
- Test prints look fine, but actual prints are faded
- Lines appear uneven or broken
- Certain channels stop printing completely
- Prints look fine at first, but rapidly deteriorate after a few minutes
👉 Often caused by ink supply issues, not the print head
■ Print Head / Damper Issues
- No improvement even after replacing the print head
- Ink does not flow even when suction is applied
- Clogging occurs near the damper area
- Air remains trapped inside the print head
👉 In many cases, the issue is not the print head itself
■ Capping / Maintenance Issues
- Ink leaks when pressing the cap
- No proper suction pressure
- Cleaning does not draw ink properly
- Waste ink flows, but print quality does not improve
👉 Capping unit deterioration is a very common cause
■ Filter / Tube Blockages
- Ink stops midway through the system
- Replacing filters may temporarily resolve the issue
- Solidified white ink is found inside tubes
- Direct connection temporarily improves flow
👉 Often overlooked, but a critical point
■ Unknown Issues (Surprisingly Common)
- No improvement regardless of what you try
- Symptoms change from day to day
- Fixed once, but the problem returns
- No clear solution even from the manufacturer
👉 Most cases are actually combined (multiple) issues
💡 Common Struggles Among GTX Users
- Unable to identify the root cause
- No clear or correct procedure available
- Information is too fragmented
- Repair costs are too high
- Especially difficult for second-hand machine owners
If even ONE of these symptoms sounds familiar,
this guide will greatly improve your ability to identify the true cause of the problem.
Rather than guessing or trying random fixes, you will learn a structured approach to troubleshooting GTX issues.At the same time, you’ll develop a deeper understanding of the machine’s structure and behavior.
