[sane-devel] Brother MFC-610 CLN scanner with network cable

But then I think, that if it works with usb, it should also work with a network cable. No. Reason: Printing on normal printers work in a unidirectional way. A normal printer driver for a normal printer produces the printer-specific data without communication with the actual printer hardware. Then the printer-specific data is sent somehow to the actual printer hardware (e.g. via simple TCP socket if it is a network printer). Scanning requires continuous bi-directional communication of the driver with the actual scanner hardware. Therefore the driver must be prepared to do this communication. If the Brother driver does not support communication via network, it will not work via network.

[sane-devel] Brother MFC-610 CLN scanner with network cable
Dear list I have a combined printer/scanner. It is connected to my home network to a switch using a network cable. After fiddling a bit, I could get the printer working nicely, thanks to nice instructions at http://solutions.brother.com/linux/sol/printer/linux/cups_wrapper_install.html I have then tried to install the scanner but I dont get it working. Maybe because I dont find any instructions or maybe because it is not possible? It seems to be prepared for usb scanners. But then I think, that if it works with usb, it should also work with a network cable. Or can I just forget about making the scanner working. I am using Suse 10.0 and a Brother MFC-610 CLN. Any recommendations would be warmly appreciated. Best regards Martin -- next part -- An HTML attachment was scrubbed...

The Canon LiDE 35/40/50 scanners are now supported in cvs. Thanks for all your work! As far as I know, you use a LiDE 35. So i marked this scanner's support as good. If you think the level of support is different, please change it in genesys.desc. I tested a Canon LiDE 50. To get it running, I had to uncomment its id in genesys.conf. I changed this in CVS. I Also changed the name of the scanners to also show the Canon LiDE 40. Also I used a build number of 7, because the last one in CVS was already 6. The test results for my Canon Lide 50: Generelly: Sometimes I have a dark vertical stripe near the left border (about 1 cm width, over the complete image). This happens in Preview but very seldomly. Also I have vertical stripes, especially in medium-bright areas. Color: 75: Works, images are a bit too bright (over-imposed). Black looks grayish and some brighter colors are nearly white. 150: Sometimes works, most of the time the scan hangs at about 95%. I.e. there is a normal scan but the scan head stops and xsane never displays the image. Also tested with scanimage. When it works, the image looks like at 75 dpi. The problem depends on image width. E.g. at a width of 20 mm, it always works at 150 dpi but not with the full width. Sledomly, I also get a segmentation fault. The log shows that this part is repeated endlessly in case of a freeze: [genesys] genesys_read_ordered_data: using filters: reorder [genesys] genesys_read_ordered_data: frontend requested 32768 bytes [genesys] genesys_read_ordered_data: bytes_to_read=6814665, total_bytes_read=6803082 [genesys] genesys_read_ordered_data: 3 lines left by output [genesys] genesys_read_ordered_data: 3 lines left by input [genesys] genesys_fill_read_buffer: start [genesys] genesys_fill_read_buffer: reading 7723 bytes [genesys] genesys_fill_read_buffer: failed to read 7723 bytes (Invalid argument) [genesys] genesys_read_ordered_data: reordering 0 lines [genesys] genesys_read_ordered_data: completed, 0 bytes read [genesys] sane_read: start [genesys] genesys_read_ordered_data [genesys] genesys_read_ordered_data: dumping current_setup: pixels: 1287 lines: 1765 depth: 8 channels: 3 exposure_time: 5276 xres: 150 yres: 150 half_ccd: yes stagger: 0 max_shift: 0 After the freeze or segmentation fault, the scanner is sometimes not found anymore. Replugging fixes that. 300, 600 dpi: Works (overimposed) in full width. Doesn't work at e.g. width 100 mm (see above). 1200 dpi: Doesn't work in full width (see above). Works at e.g. a width of 20 mm. This is much darker and has vertical stripes (calibration problem?) 2400 dpi: Same as 1200 dpi. In addition, the image is too long (factor 2). I.e., in modes like 1200x2400 dpi the x resolution must be inflated by either just duplicating pixels or, better yet, interpolating them. Gray: 75 dpi: Works, but is over-imposed. 150-600: see color 1200, 2400: see color 1200/2400 Lineart: similar to gray I also did a spot check on color 16 bit and this seems to be less over-imposed. For now, I mark the support of this scanner as minimal. I marked the Canon LiDE 40 as Untested. Can somebody please test this scanner? Thanks again, Henning

Can you give some more information so I can add it to our list of unsupported devices? It's connected to ethernet? Bye, Henning

Dear Henning When I searched like you did on the sane page, I found MFC-620CN at the bottom in the brother2 group. I am sorry that I mistyped the model number. Although I misspelled, I think there might be a misspell in the sane list as well, and that it shoul be MFC-620CLN. In the list it says usb for all scanners, even the supported ones. In the list there is nothing about network cable connections. I am trying to set it up with a network cable, I think it is ethernet (normal Internet cable). I have read the man pages of sane and saned but it did not help me yet. I will ask to Brother like you advised me.

I'll give it another try but wanted to ask first whether it is supposed to work at all. Did anyone manage to get it running? Thanks and best regards, Nick.

I copied this from the brother2 page and they claim the MFC-620CN is supported by brother2. A CLN is not mentioned on their page at all. So I guess I'll add a MFC-620CLN as unsupported? In the list it says usb for all scanners, even the supported ones. In the list there is nothing about network cable connections.

I will ask to Brother like you advised me. The Brother page says: This SANE driver will only work with devices connected through the USB interface.. That's why I listed all of these scanners only as USB. Bye, henning
