Pro Tips from Experts

This error is often related to the 0x00C1000B (Ink System Failure) error. Ensure the printer has been level and not tilted, as this can introduce air into the lines. For T1600/T2600, check the waste ink system for blockages, as this can indirectly affect priming. Running a few printhead cleaning cycles can sometimes force out air bubbles.
