26. Avoid pressing down on the carriage SECTION (00:08:55) Post-Replacement Procedure
27. Turn the printer back on
28. Wait for idle status
29. Perform an ink fill for at least 10 seconds
30. Cancel the fill process
31. Perform two consecutive head cleanings SECTION (00:09:40) Final Verification
32. Load film back onto the printer bed
33. Align media guides
34. Close the cover
35. Open DTF Station Pilot
36. Perform a nozzle check SECTION (00:10:30)

• Dampers regulate ink flow, filter contaminants, and eliminate air bubbles before ink reaches the print head
• Faulty dampers can cause inconsistent spraying, missing nozzles, or banding
• Do not test dampers frequently, as repeated removal causes wear
• Test dampers only when symptoms persist after standard maintenance
• Always rule out other causes before replacing dampers
• Sudden loss of nozzles in one channel
• Banding that appears during printing
• One color channel completely missing while others print normally
• Multiple head cleanings do not improve nozzle patterns
• Nozzle patterns remain unchanged after each cleaning
• All channels missing at once
• Issues caused by print head dryness or wear
• Ink starvation unrelated to individual channels
• If all channels are missing, consult other troubleshooting guides or contact a DTF Station technician
• Dampers on the same print head are interrelated
• A missing cyan channel may be caused by magenta or black damper pressure
• Missing black on the far right or white on the far left may indicate capping station misalignment
• Verify the capping station is centered before testing dampers
• Never grip a damper by the belly or transparent membrane
• Always hold dampers by the outer plastic frame only
• Squeezing the belly will cause ink spillage and internal damage
• Do not press down on the carriage
• Pressing downward can alter carriage height
• Handle print head ribbon cables with extreme care
• Do not pinch, pull, or bend cables forcefully
• If cable damage is visible, photograph it and contact DTF Station before continuing
• Place paper towels around the printer bed
• Cover areas near the print head and cable connections
• This prevents ink from spreading during damper removal
• Inserting the syringe damages the internal gasket
• Aim to pull at least 5 ml of ink
• The damper belly should compress under suction
• Proper damper: airtight pressure with smooth ink flow
• Faulty damper: foamy ink, excessive air, or no belly compression
• Some air inside the damper is normal and required for ink flow
• Do not attempt to remove all air
• Pushing too hard can affect print head height
• Both white dampers are connected to the same ink system
• If both white dampers are not airtight, the issue may not be the dampers
• Record video evidence and contact DTF Station before replacing
• Use scissors to slide the tube outward if needed
• Cut close to the damper edge to preserve tube length
• Inspect tube end for wear
• Trim the tube cleanly and straight if needed
• Uneven cuts can introduce air leaks
• Tube extensions are included if extra length is needed
• New dampers can be defective
• Always test before reinstalling
• Any ink leaking from the damper indicates gasket wear
• Even minor leaks justify replacement
• Wipe the gasket area and retest to confirm
• If the print head was exposed for over 30 minutes, ink fill may take up to 30 seconds
• If nozzle pattern is 90% or better, resume printing
• If not, perform additional head cleanings or ink fills as needed
• Monitor prints closely after damper replacement
• Contact DTF Station if issues persist
