Linux network scanner sane1/17/2024 ![]() ![]() It is free for personal use and written mostly in PHP. This would require the use of SANE-AirScan on the Linux client. There is also now a way to share a Windows scanner over the eSCL protocol. SANE-AirScan also supports the WSD protocol. Given the lack of difference in the way I configured the two laptops, I can only assume that the problem I was having on my first laptop (HP EliteBook Folio 1040 G3 Notebook PC) is a hardware problem. On Linux there are two different back-ends for SANE to support eSCL SANE-AirScan SANE-eSCL. It works perfectly well with scanimage -L and simple-scan. I have tested the SANE backend with the same scanner and an older laptop (Dell Latitude E6500). It looks like the problem doesn't come from a lack of support after all. Important update: works on another laptop It would have been less confusing if it was never detected. then attach the created file - journallogs - as an attachment to the bugzilla ticket. this way (if there is only one journactl process) kill pidof journalctl. trigger an action ( discovery or scanning) kill the journalctl process, f.e. I'm just a bit surprised with the behavior of scanimage -L in this case. It can be done this way: start capturing journal logs at background: journalctl -f > journallogs &. It really looks like the issue is just that the scanner is unsupported (see in particular). Update: searching the mailing list and commit history I am in the market for an upgrade to a color laser multifunction (print/scan/fax) Stack Exchange Network Stack Exchange network consists of 182 Q&A communities including Stack Overflow, the largest, most trusted online community for developers to learn, share their knowledge, and build their careers. It detects the scanner only the first time after plugging / restarting, including across modes (normal then sudo or sudo then normal). Scanimage -L behaves the same in normal and sudo mode. Try scanimage -L and read the backend's manpage. # Your USB scanner was (probably) detected. The scanner is always visible with sane-find-scanner (in normal mode or in sudo mode): found USB scanner (vendor=0x04e8, product=0x3441 ) at libusb:001:005 The scanner is always visible with lsusb: Bus 001 Device 006: ID 04e8:3441 Samsung Electronics Co., Ltd TLP 1.0 -īut this doesn't help actually. I thought it may be the same issue as in so I disabled USB autosuspend using TLP, I can see that it has been taken into account: $ tlp-stat -u I have tried using simple-scan to scan a document but I get a similar experience (I can see the scanner only if I just plug it in without testing the connection with scanimage -L but in any case, the application doesn't manage to scan even just a page). I only have to unplug and replug the USB connection to see it again (only once). Interestingly, the first time I run this command, I can see my scanner (and my webcam): $ scanimage -Lĭevice `xerox_mfp:libusb:001:012' is a Samsung Samsung SCX-3200 Series multi-function peripheralĭevice `v4l:/dev/video0' is a Noname HP HD Camera virtual deviceīut the next time I run it, I only see my webcam: $ scanimage -L I installed SANE backend ( = true on NixOS) and tested if my scanner is detected by running scanimage -L (as suggested here ). ![]()
