Motorola DS6707 User Manual

Imaging Preferences 5 - 21

Select the number of significant bits per pixel (BPP) to use when capturing a signature. Select 1 BPP for a black 
and white image, 4 BPP to assign 1 of 16 levels of grey to each pixel, or 8 BPP to assign 1 of 256 levels of grey to 
each pixel.

The digital imager scanner ignores these settings for JPEG file formats, which only support 8 BPP.

The digital imager scanner ignores 1 BPP for TIFF file formats, which only support 4 BPP and 8 BPP. 
1 BPP is coerced to 4 BPP for TIFF file formats.
