I had this with a different CIS scanner. In that case the problem was
that the USB socket (an unpowered hub) provided enough power to run the

CIS machines don't have separate bulbs, they have a series of tricolor

Hello - Apparently I have the problem named in the subject. The scanner
works, but I just get a black scan. Where can I get a bulb?
