Scanner Operation

English Hardware
1

Hello, I have a Brother MFC-J432W Multifunction. I downloaded the correct drivers from brother and it prints perfectly. The problem is it wont scan, using simple scan it shows the correct printer model but that’s as far as it goes, any ideas?

Thankyou.:\

Is this scanner connected via USB or network-attached?

For my USB-connected Brother DCP-7055 scanner, I had to add a udev rule (/etc/udev/rules.d/50-brother.rules) before I could scan

# Brother DCP-7055
ATTR{idVendor}=="04f9", ATTR{idProduct}=="0248", MODE="0664", GROUP="lp", ENV{libsane_matched}="yes"

and of course be a member of the ‘lp’ group.

If you haven’t done so already, you might want to review the following

Thankyou for your reply, i am fairly new to this so please excuse my lack of knowledge. I tried what you said but it still won’t scan, not a problem as i really only need the printer anyway. Thanks for your help.

  1. You didn’t answer my first question about how it is attached. (Network scanning takes additional steps.) Please answer that question.

  2. I’m unclear as to what you tried. Are you sure you downloaded and installed the correct scanner driver? Please confirm with

rpm -qa|grep brscan

If you’ve tried various commands or configuration, ideally you should cut and paste them (and any output) here, enclosed within

...[/CO..] tags like I have.

The udev rule I quoted was specific to my model - it would need to be adjusted with the relevant product ID for your device. That can be got with with your multifunction device attached using

lsusb



3. Some other things to check: This model uses the 'brother4' backend. For it to be active, /etc/sane.d/dll.conf should contain an uncommented 'brother4' entry.

I have a problem similar to several other threads on this list but
different enough to open new thread. The scanner works sometimes but
mostly gets an Invalid Argument error on startup with xsane, Skanlite
and the scanimage command. See results below:

/etc/udev/rules/55-libsane.rules.

CODE

Brother MFC-J6710DW

ATTR(idVendor)==“04f9”, ATTR{idProduct)==“0263”, MODE=“0664”,
GROUP-“lp”, ENV(libsane_matched)=“yes”

Errors:

CODE

@linux-x5b8:~> scanimage -L
device `brother4:bus3;dev5’ is a Brother MFC-J6710DW USB scanner
finemanruss@linux-x5b8:~> scanimage -T
scanimage: rounded value of br-x from 297 to 296.973
scanimage: rounded value of br-y from 420 to 419.962
scanimage: sane_start: Invalid argument

Example: xsane reconizes the scanner, setup looks good, Press Scan
button in Xsane GUI.

CODE

“Failed to start scanner: Invalid argument” then I close the error
message

The entry in /Udev/rules.d is where the brother install document says to
put it. (BRSCAN4)

Skanlite gets “Invalid Argument” error in preview mode.

This device with the above setting in rules and same applications all
worked in opebSUSE12.3.

Any ideas what to look at?

Help or pointers will be really welcomed.

Hi upscope

You are better off starting a new thread of your own when reporting issues with specific hardware. This is not the same the the OP reports.

One thing you might like to try is deleting ~/.sane then attempt to scan again.

Your advice got me going after several attempts:

  1. rename .scan folder - Still failed
  2. moved folder to trash , it created one one but still failed.
  3. copied folder from a 12.3 backup, and compared to 13.1 folder, ran
    using working 12.3 folder - still failed.
  4. turned off computer and printer/scanner, restarted. (have tried this
    many times before)
  5. reset all preference in Xsane, saved them, ran Xsane - it worked.
  6. saved drc file.
  7. logged in and out - scanner still working.

since I am behind in my work with the scanner, will try again tomorrow
morning after reboot.

Again thanks for your help. It it works in AM I will post a solved
message

Glad to have put you on the right path. Yes, it seems some of the default xsane parameters are not so ‘sane’ for some hardware. At least you’re up and running again. :slight_smile:
