Brother MFCL3750 now refuses to scan

Post by appalbarry »

Brother MFCL3750CDW Digital Colour All-in-One Multifunction Centre.
This worked great using the approved Brother driver package when purchased and installed in the summer, then a few weeks ago stopped scanning. I've reinstalled everything, and have tried the suggested fixes shown here and still nothing. Printing is fine, but no scanning.

I'm running:
Host: Barry-Desktop Kernel: 5.4.0-47-generic x86_64 bits: 64 compiler: gcc v: 7.5.0
Desktop: Cinnamon 4.4.8 wm: muffin dm: LightDM Distro: Linux Mint 19.3 Tricia
base: Ubuntu 18.04 bionic


Looking at the captures below I see:

Could the missing brother2 and brother1 files be the issue?

Here are the full captures:

No scanners were identified. If you were expecting something different,
check that the scanner is plugged in, turned on and detected by the
sane-find-scanner tool (if appropriate). Please read the documentation

[dll] init: initializing backend `brother4'
[dll] init: backend `brother4' is version 1.0.1
That looks normal. libsane-brother4.so.1 is found and initialized. libsane-brother4.so.1 comes in the brscan4 Brother package, which is the one for your device.

libsane-brother2 is in the Brother brscan2 package, which is not the one for your device. I do not know why it is being searched for.

My best suggestion is to comment out brother2 in /etc/saned/dll.conf.

Re: Brother MFCL3750 now refuses to scan

Hi Brian,
I liked that but it didn't solve the problem. This is all over my pay grade.

I did see two more issues that might be causing this? Something about v4l and pint not loading.

Code: Select all

[dll] load: couldn't open `/usr/lib/sane/libsane-pint.so.1' (No such file or directory)
[dll] load: couldn't find backend `pint' (No such file or directory)
Here's the whole output:

Re: Brother MFCL3750 now refuses to scan

Post by brian_p »

I did see two more issues that might be causing this? Something about v4l and pint not loading.
I imagine commenting those two out would see the complaints disappear but not lead to scanning.

Your device has an AirPrint service. I would set it up with driverless printing and scanning.
