This error indicates a problem with the service station assembly, which is responsible for printhead cleaning, capping, and spitting. A faulty service station can lead to print quality issues or prevent the printer from operating.
- 1
Open the top cover and carefully inspect the service station (usually on the right side) for any paper scraps, dried ink, or foreign objects.
- 2
Gently try to move the parts of the service station (e.g., wipers, caps) if accessible, to ensure they are not stuck. Do not force them.
- 3
Turn off the printer, unplug it, wait 5 minutes, then plug it back in and power it on.
Model-Specific Notes: • T-Series (e.g., T930, T1530): These models have a more complex service station. Ensure the printhead cleaning fluid reservoir isn't overfilled or leaking. Check the wiper blades for wear. • Z-Series (e.g., Z6100, Z6600): The service station on these models can accumulate significant ink residue. A thorough cleaning, especially of the capping stations and wipers, is often necessary. Expert Insight: Use a flashlight to inspect the service station thoroughly. Look for excessive dried ink, especially on the printhead caps and wiper blades. Clean with a lint-free cloth and distilled water or printhead cleaning solution. Check the service station motor's connections. Sometimes, manually moving the carriage over the service station (with the printer off) can help identify if the service station is physically stuck. If the motor is faulty, the entire service station assembly usually needs replacement.

A maintenance area on the right side of the printer where the printheads are capped and cleaned when not in use. It prevents ink from drying in the nozzles.
A maintenance routine where the printer fires ink through all printhead nozzles into the service station to clear potential clogs and keep nozzles fresh.
The mechanism that moves the printheads back and forth across the media during printing. It rides on a guide rail and is driven by the scan-axis motor via a belt.
The built-in blade mechanism that automatically cuts media after each print job or at specified intervals.
A calibration process that ensures all printheads are precisely aligned relative to each other for accurate color registration and sharp output.
