Solution to Ink City After Removing Eco Solvent Ink from Printer Machine

Greetings,

Question: 
I cleaned old eco-solvent ink from my printer's tanks, dampers, and lines. After flushing and cleaning it, I attempted to prime the dampers, but no ink would flow. I checked the halter top to see if it was open, but nothing moved. I also removed the damper's line, yet no ink is running out. Did I ruin the tanks while cleaning them? How do I fix this and go back to ordinary ink?

No Ink Flow (Common Causes and Solutions)
 
Divide and Conquer the System
The initial move is to segment each area of the ink supply framework to pinpoint where the impediment might be happening.

• Tanks: Check that the ink tanks are vented correctly. If the vent is closed or clogged, it can create a vacuum that stops ink flow. You can test this by blowing gently into the vent or ensuring the vent hole is opened completely.
• Lines: Try disconnecting the ink lines from the dampers and seeing if you can manually draw ink through the lines with a syringe. If ink does flow freely, the problem lies further down.
• If the ink isn't getting to the dampers, they could be clogged. Soak your dampers in a cleaning solution that works for your ink type, and try to make sure you can use a syringe.

Check for Residual Clogs
Eco-solvent inks are thicker and may leave residue even after a flush process. This gunk can solidify and prevent the normal flow of ink.

• Re-Flush the System: Using dye or pigment inks, use a high-quality cleaning solution compatible with eco-solvent. Iterate the solution through the tanks, lines, and dampers to ensure any remaining screening material is dissolved.
• Inspect and Clean Filters: Certain printers utilize in-built filters as part of the ink supply system. Inspect these filters and clean or replace them as necessary.

Test Ink Flow from the Tanks
Once the vent is open, you can disconnect the ink line straight from the tank and use a syringe to carefully pull the ink out. If no ink comes out, the tank's outlet may be blocked or damaged.

• Please check the outlet valves for clogs or damage. If cleaning damaged them, they might need to be replaced.
• Re-prime the Tank: When you refill the tank with regular ink, suck it in and out using the syringe again to ensure the flow is adequate.

Inspect the Pump System
If your printer has a pump to help with ink flow, please ensure it works properly.
Pump Maintenance: Clean the pump and verify it isn't blocked by dried ink or cleaning solution residue. Replace any worn-out or damaged parts.
 
Reassemble and Test
After you have inspected and cleaned all parts:

• Reconnect ink lines to dampers and use a syringe to prime manually.
• Please perform a nozzle check to ensure the ink flows and prints correctly.

Did the Tanks Get Damaged During Cleaning?
Cleaning alone seems unlikely to ruin the tanks unless strong chemicals are involved or the tanks are handled roughly. But if the tanks' seals or valves were damaged during the cleaning, they might need to be replaced to work correctly.
