Re: [sane-devel] Need sane docs

Xsane has no networking code in it. Everything you have described so far sounds like a problem in the brother4 backend. I suggest you try the same test using scanimage at the command line, and if it is still slow, compare to the windows driver. If you see a difference, ask Brother about brother4.

Re: [sane-devel] Need sane docs

I doubt a gigabit Ethernet connection will make any significant difference. Data rate from your scanner is dependent on the mechanical speed of the sensor and scan resolution. If you scan a page 8.5 by 11 inches at 600 pixels per inch resolution with 24 bits per pixel, there is about 100

Re: [sane-devel] Need sane docs

"Timed wait" is the final stage when a TCP connection is closed. TCP has the notion of "maximum segment lifetime" - how long a datagram might remain somewhere in the network. Before a connection is completely closed, it remains in the "timed wait" state for twice this maximum segment lifetime.

Re: [sane-devel] Need sane docs

Gene- if your scanner has ethernet connectivity, you don't need to use the net backend or saned. Those are basically adapters that allow you to convert a non-networked scanner into a networked one, by using a saned server as an intermediary. I think you need to see if the brother docs list any

Well, that implies that we are handing control to the brother4 backend, but it is not finding any scanners. Perhaps try the same as root? allan On Tue, May 3, 2016 at 8:06 PM, Gene Heskett wrote: > On Tuesday 03 May 2016 17:54:54 m. allan noah wrote: > >>

We cannot really help you on the brother stuff, since it is closed source, and not produced by us. But, we can suggest that you try the following: comment out every line of dll.conf except for the the brother lines you need, and one other random backend (maybe, fujitsu). Then run:

Greetings all; I just bought a Brother MFC-J6920DW, and installed the brother linux .deb drivers that are "supposed" to let xsane run the scanner. But xsane makes no attempt to access it even if I plug in a USB cable. It did install the name "brother4" in /etc/sane.d/dll.conf, but I can't
