I have a MF4890DW all-in-one laser printer. When I need to scan a document, I use "remote scanning" and initiate the scan from my Mac using the "MF Toolbox" software. The scanned copies always come out dull - many times not capturing anything writtem with a blue or even black ink pen (for example my signature in a document). How do I change the scan settings to increase the density of the output? I use the black/white or grey scale mode for scan and not the color mode. The main reason is that the color mode generates a much bigger file than black/white.
Thanks.
