The following scans help evaluate the digitization quality of transparent and reflective originals (KODAK IT8.7/2 Q-60 R2/E3A color targets). The scanning parameters were selected according to the driver’s three main modes: without color correction (Color Settings: None), with an ICM profile (Color Settings: Canon ColorGear), and with automatic tone correction (Color Settings: Recommended).

I want to draw your attention to the fact that you’ll only get good scans if you’ve turned on automatic lamp calibration before each scan operation in the driver’s settings:

This item is off by default and leads to over-bright images after the scanner has worked for some time – the parameters of the mercury lamp change noticeably as it gets warmer.

To end this section of the review I want to show you a scan of volumetric objects – a few soft-tip pens. This scan helps evaluate the scanner’s depth resolution.
