From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:0.9.7) Gecko/20011221 Description of problem: When scanning using the Epson backend, colour scans come out in greyscale only. This is with xsane, xscanimage and scanimage. Version-Release number of selected component (if applicable): How reproducible: Always Steps to Reproduce: 1. Scan a colour image 2. 3. Actual Results: The image comes out greyscale Expected Results: The image should scan in colour Additional info: I'm using an Epson GT7000 SCSI scanner, connected to a Tekram DC-395UW SCSI controller. Kernel is 2.4.17, with Kurt Garloff's Tekram driver patch. This same setup (an earlier kernel, with the same patch) worked fine on RH7.1 on the same machine. When I upgraded to 7.2, it refused to scan in colour. Using the SANE_DEBUG_EPSON environment variable didn't provide any useful information that I could see.
Please try this: SANE_DEBUG_EPSON=128 SANE_DEBUG_SANEI_SCSI=128 scanimage -L and attach the output.

Thanks. Reported upstream.
Problem solved. It *is* scanning in colour, it's just that the test image I was scanning was very close to grey. The slight blueish tint in the original image was being lost (presumably due to the limitations of the scanner), and the resulting image came out grey. When I tried it with a "normal" colour image, it works fine. Sorry for the false alarm...
