What This Error Means

The integrated scanner (if present) failed its internal calibration process. This can result in poor scan quality, inaccurate color reproduction, or the inability to scan documents.

Step-by-Step Troubleshooting Guide

1
Ensure the scanner glass and the white calibration strip (usually located on the underside of the scanner lid) are perfectly clean and free of dust, smudges, or debris.
2
Close the scanner lid completely. Ensure there are no documents on the scanner glass.
3
From the printer's control panel, navigate to the scanner settings and initiate a manual scanner calibration if available.
4
If the error persists, turn off the printer, unplug it, wait 30 seconds, then restart.

Pro Tips from Experts

Model-Specific Notes: • T-Series (e.g., T830 MFP, T2600 MFP): These integrated scanners often have a dedicated calibration routine in the service menu. Ensure the white reference strip is not discolored or damaged. • Z-Series (e.g., Z9+dr with integrated scanner): Check for firmware updates specifically for the scanner module. Expert Insight: Use a lux meter to check ambient light levels around the scanner; excessive or fluctuating light can interfere with calibration. Inspect the scanner lamp for proper illumination during calibration. If accessible, check the scanner's internal cables for proper seating. Sometimes, a full NVRAM reset (if documented in the service manual) can clear persistent calibration data issues, but this should be done with caution as it resets other settings.
