Ink Supply Station (ISS) Valve Error

Model-Specific Notes: • T-Series (e.g., T1700, T2600): These models often have a modular ISS. The error might pinpoint a specific color's valve. Check for proper seating of the ink tubes leading from the ISS to the carriage. • Z-Series (e.g., Z9+, Z6): The Z-series ISS is typically robust. This error could indicate a more significant issue like a failing pump or a sensor within the ISS that monitors valve position. Expert Insight: When troubleshooting, pay close attention to the specific color or bank of colors that might be affected if the error is intermittent or accompanied by print quality issues. Visually inspect the ink tubes for air bubbles, which could indicate a leak or a valve not sealing properly. If accessible, check the electrical connectors for the valve solenoids. A common issue can be dried ink preventing the valve from fully closing or opening. A service technician might use diagnostic tools to manually cycle the valves and check their response.
