Model-Specific Notes: • T-Series (e.g., T920, T1500): The alignment sensor is typically integrated into the carriage assembly. Ensure the printheads are correctly latched. • Z-Series (e.g., Z6610, Z6810): These printers use very precise alignment. Check for any ink residue on the sensor or the platen area where alignment patterns are printed. Expert Insight: A dirty sensor is the most frequent cause. Ensure the cleaning is thorough but gentle. If the error persists, remove all printheads and then reinstall them, ensuring they are fully seated. Check the trailing cable for any damage or kinks, as it carries the sensor's data. If the sensor is physically damaged or the error remains after cleaning and reseating, the carriage assembly (which includes the sensor) or the main PCA may need replacement.
