Troubleshooting

•

Insert the syringe in the purging port (next to the ink pressure sensor) for the color selected, and 

slowly push the ink until it clearly reaches the purge bags. 

•

If you see a bubble of air within the syringe, do NOT push it within the tube, refill the syringe if 

needed, after first remove the bubble of air from the syringe (need to first disconnect the needle 

from the purging port). 

•

Remove the syringe from the purge port with a cloth around the needle to prevent spills. 

10.

Start the printer in diagnostic mode. 

11.

Check the 6 main ink electro-valve, by running the test 4.6 ISS Electro valves. In case you do not ear 

the ‘click click’ coming from the corresponding electrovalve that you are testing, tap vigorously on the 

body of the electrovalve with a tool such as a screwdriver (do NOT tap on the tube at the front of the 

electrovalve, else you might create an ink leakage). 

12.

Remove the 3 Printheads. 

Make sure to insert the syringe far enough into the port. In order to insert the ink correctly, the 

tip of the syringe must engage a small spring inside the port.

If you apply too much force to the syringe, you may damage the ink system. If there seems 

to be too much resistance, stop pushing the ink with the syringe and try to identify possible problems.

Never look away from the syringe. If you need to look at the purge bags or something else 

in the room, set down the syringe first. The ink system components are easily broken.
