I wonder if 'vuescan' supports brother better, i just today bought it for my old hp 5370c which is detected by sane but it has never been able to handle it correctly. Vuescan demo is also on slackbuilds.

I tried these commands by replacing them with brother4:bus2;dev3 since im using USB, and both give me 37 bytes files each and output the following in terminal:

Code:
scanimage: rounded value of br-x from 215.9 to 215.88
scanimage: rounded value of br-y from 355.6 to 355.567
I don't know what that means. Also, not sure this matters, but i'm logged in as root in Slackware, as opposed to just a regular user in Ubuntu. So, i do not get the root warning prompt from XSane to "Continue at your own risk" in Ubuntu.

Vuescan does list MFC-J870DW as supported on their website. Ubuntu has Simple Scan too, but i think that is based off XSane.

Hello,

I just purchased a Brother MFCJ-870DW All-In-One but I am about to return it. I have the same problem described in this chain:

Slackware 14.1 (linux 3.10.17)
sane 1.0.24-x86_64-1
brscan4-0.4.2-3.x86_64

I choose the Brother printer because Brother has had good linux support in the past. I use the USB connection. The printer and FAX printer drivers installed OK and work fine.

The scanner driver installs OK, but doesn't appear to work. From either an ordinary user, or root:

cher:/home/mradtke scanimage -L
device `brother4:bus1;dev1' is a Brother MFC-J870DW USB scanner
cher:/home/mradtke

cher:/home/mradtke scanimage >piggy
scanimage: rounded value of br-x from 215.9 to 215.88
scanimage: rounded value of br-y from 355.6 to 355.567
cher:/home/mradtke

In the second case, scanimage just quits. No error message. The
output file contains:

cher:/home/mradtke cat piggy
P6
# SANE data follows
1680 2322
255
cher:/home/mradtke

I tried the wired ethernet connection with the same results.

I tried a different computer with slackware 14.0, 32 bit, with the 32 bit drivers and got same results.

I too only have the 24-bit color[Fast] option. After reading this chain, I tried scanning with the True Grey option and it works fine.

Do you have any advice on how to proceed, or should I just return the printer?

Thanks,
Mike
