As scanners of the second generation, these devices were offered as daylight scanners in three versions with recording drums (cassettes) of different sizes.
The length was around 2340 mm; the weight about 670 kg.

 

The operator could not see the image while adjusting the color corrections to assess the effect of the color corrections (the image was not yet scanned or saved). So, the operator needed a lot of experience to adjust color corrections because the result was only visible when the image was printed.
The scanner can change the scale of an image during scanning, i.e. generally enlarging was used.

The scan line is temporarily stored, read out with the next rotation and, after being color-corrected, exposed to film mounted within the cassette.

 

So it is a scanner-recorder (popularly called "scanner"). It wasn't until the early 1980s that separate scanner and recorder devices came onto the market with the DC 3000 series.
