HP Designjet Color 3D Printer - Diagnosing loss of extrusion

Occasionally, the printer’s head may experience loss of extrusion. This will be evident by observing one of the following:
  • The head is moving with no material coming out of either tip.
  • The height of the model and support materials are not equal.
  • Sagging structures due to lack of support materials.
  warning:
The head area is hot. Use gloves when working in this area of printer.
  1. From the display panel press Cancel and remove parts from the printer.
  2. Insert a new modeling base.
  3. From Idle, press Maintenance.
  4. Press Machine.
  5. Press Head. The head will move to the center of the chamber and the Z platform will change position. The display will read: Model Drive Motor Stopped.
  6. Determine if there is a model material extrusion problem by pressing Forward (command will be available after head reaches operating temperature). Watch the model tip (right tip) for any extrusion (material purge).
      note:
    You may need to wait up to 30 seconds before extrusion will begin as the tip may need to reach operating temperature.
  7. Press Stop to stop the extrusion.
  8. If material did NOT flow from the model tip, recover from loss of extrusion. If material steadily flowed from the model tip, the model tip is functioning properly.
  9. Test the support material tip by choosing: Select Drive.
  10. Determine if there is a support material extrusion problem by pressing Forward. Watch the support tip (left tip) for any extrusion (material purge).
  11. Press Stop to stop the extrusion.
  12. If material did NOT flow from the support tip, Recover from loss of extrusion. If material steadily flowed from the support tip, the support tip is functioning properly.
  13. Return the printer to the Maintenance state - Press Done, then press Yes when the printer displays Is Material Loaded?
  14. Press Done until back at Idle.
