Cleaning, calibration, and update procedures depend on the scanner model and workflow. Use the manual and resources for the exact part number.
Follow model-specific instructions
Power down or disconnect the device when the manufacturer directs. Use only the recommended cleaning materials and method; do not apply liquids, abrasives, or generic sheets without confirming they suit the model. Calibrate only when the documentation or support procedure calls for it.
Protect the established workflow
A driver, firmware, SDK, operating-system, or application change can affect capture and output. Check versions, licensing, and compatibility, preserve the known configuration, and validate the workflow with representative documents before deploying a change.
If streaking, feed errors, or unexpected output continues, record the model, operating system, application, error message, and steps already taken. Maintenance can help, but it does not guarantee a particular result or service life.
