Scanner Calibration Tips

What Are These Best Practices For?

These best practices are to ensure you get the best scans for your inspections and specifically for:

• Contex: A2 and R44
• Microtek: A0

Why Use this Feature?

Not properly following these tips can lead to the calibration failing. Unclean scanners, damaged calibration sheets, and failing to calibrate according to usage may cause issues with image stitching, which can cause the calibration to fail.

When To Use It

• When image stitching occurs.
• For camera alignment issues.

Expert Tips

• If calibration fails, redo the calibration but ensure the marker placement is correct.
• Use the white microfiber fabric and isopropyl alcohol cleaner to clean:
– Scanner glass
– White rollers on the R44
– White panel on the A2

• Calibration sheet needs to be:
– Preserved away from light
– Kept in original packaging to be undamaged
– Void of any creasing, tearing, or fading
– Replaced annually

• Calibration frequency is based on scanner usage:
– If the scanner is running extensively from morning to night, perform weekly
– If the scanner is running a few times per day, perform monthly
