• Code: 22.05.01:83 ... 22.05.07:83
• Description: Ink pressure sensor X not calibrated. Run IDS diagnostic. If the problem persists, call your support representative.
• Causes: a. Ink pressure sensor not calibrated b. Ink pressure sensor broken
• Remedy: 1. Check that the ink cartridge is in the right position, with nothing on it. 2. Run the "Ink pressure sensor calibration" diagnostic. 3. Compare the values returned with the ink sensor board label values. 4. If the values are different, set label values, otherwise run the "Automatic electrovalves and ink pressure sensor check" diagnostic to stabilize pressure, and go back to step 1. 5. If this fails, change the ink sensor board and recalibrate it.

• Code: 22.06.00:06
• Description: General ink leakage. contact your support representative.
• Causes: a. A genuine ink leakage b. A false ink leakage c. False ink leakage detection
• Remedy: 1. Check the ink sump to identify leakage color. 2. Check the faulty ink line, paying attention to the ink pressure sensor, ink four-way valve, electrovalves, tubes, and fitting. 3. Replace the leaking part. 4. Clean the system. 5. Run the ink system leakage diagnostic, to check that it is fixed and clear the error.

• Code: 22.07.01:01, 22.07.02:01
• Description: ISS PCA0X Adc Ads7828e not responding. Reboot the printer and run subsystem diagnostics. If the problem persists, call your support representative.
• Causes: Internal ISS PCA malfunction
• Remedy: 1. Check LED status lights. 2. Check ISS PCA connections. 3. Replace ISS PCA.

• Code: 22.07.01:04, 22.07.02:04
• Description: ISS PCA0X GpioExpander not responding. Reboot the printer and run subsystem diagnostics. If the problem persists, call your support representative.
• Causes:
• Remedy: 1. Check the ISS PCA LEDs. 2. Check connections. 3. Replace the ISS PCA.

• Code: 22.10.01:30, 22.10.02:30
• Description: APS air pressure out of range 0X. Run IDS diagnostic. If problem persists, call your support representative.
• Causes: Air pressure sensor valves have been detected as out of the expected measurement range. Expected pressure between -0.2 and 7 psi; for the system error to be triggered the condition must be repeated for 1 minute.
• Remedy: 1. Check the connections of the air tube to the air pressure sensor in the ISS board. 2. Disconnect the tubes and perform a visual inspection of the system, in case of doubt blow into the tube to ensure there is no blockage towards the relief valve. 3. Replace the ink system main board.

• Code: 22.10.01:31
• Description: APS pressurize error 01. Run IDS diagnostic. If problem persists, call your support representative. The air system is unable to pressurize to the expected working pressure, which, depending on the actual working cycle, could be 5.2–5.6 psi (normal working pressure) or 3.6–4 psi (during refilling the non-refilled side is pressurized to prevent backwards refill).
• Causes: a. Air tube disconnected from the air system b. Air pump failure (pump or ISS PCA failure) c. Air pressure bottle leak d. Air tube leak (tube damaged) e. Air relief valve failure f. Intermediate tank leak g. Air sensor failure, leading to ISS main board failure h. Intermediate tank supports failure
• Remedy: 1. Review all air tube connections and ensure that there is no disconnection (tubes from pumps and relief valve to tap, tubes from tap to intermediate tanks). 2. Perform the front and rear air pumps diagnostic procedures. See Table 5-10 Ink delivery system. 3. If the pumps do not work, check pump connections and verify pin integrity. 4. If connections are correct, connecting to another working port and start the pump. 5. If the pump works with another port, replace the ink system main board. 6. If the pump fails, replace the air pump. See ISM pump and relief valve. 7. Check that the pressure bottle cap is tight and there is no leakage. 8. Pressurize the system and check for any failed tube. Leave the pumps on test with diagnostic procedure , the pump will operate until 6 psi is reached. 9. Check relief valve is closed and air is not escaping from it when pressurizing. Swap the relief valve from the other side to verify that it is the relief valve that is failing. If the relief valve fails, replace it. See ISM pump and relief valve. 10. Swap all intermediate tanks and ensure that there is no leak. If a leak is detected, swap the intermediate tanks again one by one until the leak is discovered. Replace the intermediate tank as appropriate and force-fill intermediate tanks. See ISM intermediate tank. 11. Swap air pressure sensor tube connections to the PCA and display values if required. If the sensors do not have similar behavior, replace the ISS PCA. See ISS PCA. 12. Try to adjust tubes and check connections, clean if required. 13. If necessary, replace the ink circuit module. See ISM ink circuit module.
