IT8 Calibration - Target Bounding Box Skewed

[BobF]

I'm trying to calibrate my scanner, a V750. I'm using v6.6.2r5 and a 4x5 transparency target. I have the reference file downloaded. I launch the IT8 calibration process and it does a prescan. Then it does another scan at some zoomed in level. The target bounding box is skewed on screen but because the view is zoomed in, there's no way to adjust it. When the reference file is located, the software, predictably, informs me that the bounding box is not aligned properly, to hit Cancel, go back and realign the box. I do this. I launch the calibration utility again and the same thing happens. In this second, zoomed in view, the box is skewed. Because the view is zoomed in, I can't adjust the box. This is an infinite error loop.

Please advise.

Dear customer,

Did you place the target in the middle of the scan area?

Please also try rotating the target 90°.

kind regards,
