Hi, i succeeded to enable raw scanning on my HP Deskjet 4615 with this patch. The solution seems to be pretty generic, but there might be good (as opposed to "good") reasons it is disabled by default. Maybe it gives unexpected results with some hardware. Also, it gets a bit "quick and dirty" in the function that calculates line sizes (i had to disable the "given" values in favour of the "guessed" (and more correct) ones), but at least it works fine for me.

I have a Deskjet 3520 All-in-one and no matter what I do, scans always arrive with JPEG artifacts. For example, with hp-scan, when I disable compression, I get the following error message: "error: Unable to set option compression to value None" When running XSane, in the advanced settings menu, I get JPEG as only compression option. Manually setting the compression to "none" in the drc file has no positive effect either. In any case, scans arrive with severe JPEG artifacts. Used hplip version is 3.13.10 on Kubuntu 13.10. I've attached the output of hp-check.
