H550 AE Rev.: 007 kortho KGJ X-series

8-19

Fig. 8.24 Ink reservoir with prime bulb attached.

5. Hold clean paper tissues or a waste container in front of the printhead to collect ink.

6. Squeeze the prime bulb completely just one time to prime the printhead. Prime in bursts of about

three to five seconds to remove any air bubbles out of the ink system.

7. Repeat priming until ink squirts from all the nozzles.

8. Remove the prime (gently, to avoid a pressure wave within the ink tubes) from the fitting of the ink

reservoir to stop priming the printhead.

9. Let the ink run of the front plate and clean the frontplate carefully without touching the nozzleplate

of the printhead. Use some solvent, the type that is compatible with the ink – no other liquids, if

necessary.

10. Rotate the printhead housing back to the print position.

11. The printer is now ready to print.

Why is my Kortho Printer not printing on request?
- T
  Tim MurphyAug 20, 2025
  The Kortho printer might not be printing because the system is in pause mode (the red indicator is lit, and a warning is displayed on the screen). Another reason could be that the number of prints has reached the value set in print count, indicated by the green status LED flashing on the coding unit and the status screen showing the print count. Also, the print request sensor or cable could be defective or not sensing the product/mark. Finally, the system might be in error mode, indicated by the orange LED on the screen and an active general alarm output.

What to do if Kortho GraphicJet X control unit does not power up?

  Dr. Wesley ThomasAug 22, 2025
  If the Kortho Printer control unit does not power up, check the following: ensure the mains voltage is present, the power cable is properly connected to the control unit and is not damaged, and the ON-OFF switch is in the I position. Also, check the fuses in the power entry module (X01) and on the power supply board, making sure the LEDs beside the fuses on the power supply board are lit. Verify that the internal mains wiring and the 48VDC and processor board wiring are connected properly. Ensure the backlight cable of the user interface panel and the user interface panel-flat cable are properly connected and undamaged. If there is a burning smell, contact your local dealer. Remember to disconnect the power cable (X1) from the mains power supply first.
