 Troubleshooting

175

It has not been possible to reach the working pressure in the IDs system. The IDS pumps ink towards the 

bag inside the intermediate tanks which push the ink out of through the ink tubes.

The pressurization value (in either of the two side) in normal working conditions is between 5.2-5.6 psi. 

If this value is not reached within 60 seconds of starting the pumps, the error is triggered.

A.

Air leakage from any of the systems on either side of the printer.

B.

Air pumps not working

C.

Relief valves not closed.

D.

Air pressure sensors not working correctly

1.

Across the ISM, start the air pumps of both sides (diagnostics 4.15.5 and 4.15.6) and check for pos-

sible air leaks (tubes broken or pinched, air pressurization bottles not correctly closed, tubes not cor-

rectly connected. Repair as required

2.

While the air pumps are pumping air though the system, check they are all working correctly. 

Replace any pumps that are faulty  page 610.

3.

Operate the relief valves with diagnostics 4.15.7 and ensure the correct operation, replace the 

valves if they do not work  page 618.

4.

Leave the pumps running from the previous test, and check the increment of pressure with diagnostics 

4.15.8. If there is no air leak and pressure does not raise, replace the ISS board.

the ink system is set as not purged and requires the purging procedure or the purging procedure has not 

been completed.

There two things that are used to trigger the error. The ISM normally is set as purged and the TRS is set 

as purged, the error is displayed when any of the two system are not set as purged.

ISM as purged is set after diagnostics utilities 0.1 Purge ISM and 0.2 fill Intermediate tanks are completed 

successfully. This as purged is set after diagnostics utility 0.3 Purge Printer tubes is completed successfully. 

The two parts can be reset by an unsuccessful refill utilities or by setting the printer for transportation and 

accepting transportation at low temperatures.

A.

Purge not performed.

B.

Purge performed but not finished

C.

Purge completed via manual procedures.
