(1) Log into the “Service” mode.
(2) Using the Ink Pump, empty all remaining INK from the ink jet.
(3) Turn the Ink Pump off or deactivate the ink jet.
(4) Remove the White Meniscus Filter from the Pump Box.
(5) Place the Pump Box Tubing previously connected to the top of the White Meniscus Filter and insert the same tubing directly into the Luer Fitting (the location the White Meniscus Filter was screwed into).
(6) Disconnect the Pump Box Tubing connecting to the Meniscus Needle Valve.
(7) Insert the Pump Box Thumb Screw into the Pump Box Tubing previously connecting to the Meniscus Needle Valve.
(8) Remove the Brown Meniscus Filter and small tubing located on the exhaust port of the Meniscus Pump.
(9) Attach a 12 inch or longer silicone tubing to the exhaust port of the Meniscus Pump and place the other end into an empty Ink/Flush bottle.
(10) Remove the Head Cover.
(11) Carefully disconnect the soft Meniscus Tubing from either the Vacuum Tank Nipple (located near the leg of the Vacuum Tank) or from the Meniscus Sensor (location P1).
(12) Attach a 12 inch or longer silicone tubing to the Vacuum Tank Nipple or to the existing Tubing previously connecting to the Meniscus Sensor and place the other end into a clean bottle of Acetone.
(13) Go to the “Settings” Tab located within the GT Editor and ensure the “Meniscus Setting” is at 16MB (for GT64s) or 7MB (for GT72s).
(14) Go to the “Pneumatics” Tab located within the GT Editor.
(15) Right click over the Meniscus Pump Icon (large rectangle) located at the top-left portion of the screen/animation and select “On”.
(16) Right click over the Meniscus Solenoid Icon (small rectangle) located at the top-left portion of the screen/animation and to the right of the Meniscus Pump Icon then select “On”.
(17) Carefully disconnect the Ink jet from the Slide Mount or pull the entire mount off of the rail.
(18) Rotate the Head 90 Degrees so the Solenoids are facing down
(19) Allow time for the Acetone to enter the Vacuum Tank and exit through the exhaust port of the Meniscus Pump until the evacuating fluid is completely clear.
*Trouble Shooting if there is no Acetone entering the Vacuum Tank:
- Ensure the “Backplane Active” and “Active” bar/buttons are not selected or “pushed down”.
- Confirm the White Meniscus Filter and the Brown Meniscus Filter have been
- Check that both the Meniscus Pump and Meniscus Solenoid are “On” and the Meniscus Setting is at 16MB (for GT64s) or 7MB (for GT72s).
- Confirm that all of the connections are correctly located and there are no leaks or kinks in any of the
- Touch the Meniscus Pump while it’s “On” to feel if the Pump is vibrating and that the Meniscus Solenoid is hot while “On”.
- Turn both the Meniscus Pump and Meniscus Solenoid off and on then
- Exit the “Pneumatics” screen then retry manually turning the Meniscus Pump and Meniscus Solenoid “On”.
- Confirm the GT-Editor still has communication with the inkjet; check the power, the Switch, Rip Cables, reset the GT-Editor, Reset the Base Unit, or turn off the Base Unit then reseat the Firepulse Cards after 30 seconds before another
- Refer to the pictures located at the bottom of this
*Part Replacement if there is no Acetone entering the Vacuum Tank and after unsuccessful trouble shooting:
- Replace the Meniscus Pump as it may be weak and require
- Replace the Meniscus Solenoid as it may be sticking and require
(20) After confirming the Vacuum Tank and Meniscus Lines are clear of ink, pull the tubing out of the clean Acetone bottle and allow air to be pumped through the Vacuum Tank and Meniscus Line for a minimum of 30 minutes.
(21) Ensure the Meniscus Line and Tubes are clear of all fluid then turn off the Base Unit while 2
reconnecting all of the original tubes – Do not reattach the White or Brown Meniscus Filters yet.
(22) Carefully place the Ink jet back into the upright position of the Slide Mount or to the rail.
(23) Turn the Base Unit back on and reintroduce Ink into the ink jet.
(24) Test the printer to ensure the system still functions properly.
(25) Wait a minimum of 6-8 hours of active use before reattaching the White or Brown Meniscus filters – this helps prevent the Meniscus Filters from clogging if residual Acetone is still in the Meniscus Lines or Tubes.
