If you have a TRIOS 3 scanner, please see this article instead. If you are not sure what type of scanner you have, see here.

Calibration of the scanner guarantees that the scanner will have high accuracy and ensures that your scanned image will display correctly and with correct coloring on screen and in print. You need to calibrate the scanner regularly, especially after heavy usage, to avoid decreased scan quality. See here to learn when you need to calibrate the scanner.

Initiating TRIOS 4 Calibration: Quick Start Guide

From a reminder message in the software. If 20 or more scans are done with one of the TRIOS 4 scanner tips, a pop-up will appear.

Manually from the Scanner Management page in Unite Settings.
- Open Unite and go to More > Settings > TRIOS > Scanner Management > Calibrate.

Calibration can also be done when you have started scanning a case by clicking Tools on the scanning page and then Calibration.

Regardless of the starting point, you will see a pop-up window with instructions for calibration once it has been initiated.

TRIOS 4 Calibration Kit Components: Essentials for Accuracy

TRIOS 4 scanning tips:

TRIOS 4 is equipped with smart scanning tips with the "number (#) of use" counter for an optimal scanning experience. All new tips delivered with your TRIOS 4 system are calibrated already, so you can start using them right after sterilization.

Any new scanner tips bought as spare accessories need to be calibrated before the first use.

Each smart scanning tip can be used for scanning up to 20 times before recalibration will be needed. The individual number of the tip and the number of scans taken with the tip is shown on the Scanner Management page in Unite Settings (More > Settings > TRIOS > Scanner Management):

TRIOS 4 Scanner Calibration Process: Detailed Steps

Attach the scanning tip to the scanner facing downwards; make sure that the front glass of the scanner tube and the scanner tip mirror are clean and sterilized.
Mount the Calibration Adapter onto the scanner tip.
Remove the protective plastic sleeve from the Calibration Target.
Insert the Calibration Target into the Adapter with the color side (side A) facing up and click Calibrate:

After calibration on side A has finished (approximately 10-15 seconds), remove the Color Calibration Target and turn it over so that the grey side (side B) faces up.
Insert the Target back into the Color Calibration Adapter and press Next:

This step takes up to 30-50 seconds.
Once the calibration is complete (approximately 30-50 seconds), the software will prompt you with a message where you should click Next. If needed, the calibration process should be repeated for other scan tips.

Remove the Calibration Target and Adapter from the scanner and put the Target back into the protective sleeve:
