Memorex MEM 48U scanner

I am trying to get this scanner to work. According to this link my scanner should be supported in SANE

http://www.sane-project.org/sane-mfgs.html#Z-MEMOREX

I have SANE installed and it seems to be detecting the scanner properly. Here's the output of a couple of commands:

Code:

yuchai@livingroom:~$ sane-find-scanner



  # sane-find-scanner will now attempt to detect your scanner. If the

  # result is different from what you expected, first make sure your

  # scanner is powered up and properly connected to your computer.



  # No SCSI scanners found. If you expected something different, make sure that

  # you have loaded a SCSI driver for your SCSI adapter.

  # Also you need support for SCSI Generic (sg) in your operating system.

  # If using Linux, try "modprobe sg".



found USB scanner (vendor=0x05d8, product=0x4005, chip=GT-6816) at libusb:002:004

  # Your USB scanner was (probably) detected. It may or may not be supported by

  # SANE. Try scanimage -L and read the backend's manpage.



  # Not checking for parallel port scanners.



  # Most Scanners connected to the parallel port or other proprietary ports

  # can't be detected by this program.



  # You may want to run this program as root to find all devices. Once you

  # found the scanner devices, be sure to adjust access permissions as

  # necessary.

yuchai@livingroom:~$ scanimage -L

device `artec_eplus48u:libusb:002:004' is a Memorex MEM 48U USB flatbed scanner

In my mind this means the device was set up properly in SANE.

When I launch xsane, however, I get an error message:

Failed to open device 'artec_eplus48u:libusb:002:004': Invalid argument

What am I missing here? Thanks in advance for any help you can provide.

I am no expert on scanners or sane, and I had some difficulty getting my scanner to work (an epson). However I looked at your model, and it seems the product (product=0x4005) is not listed in /etc/hotplug/usb/libsane.usermap which I think is necessary. There is a close match, at least in my version of the file, as follows:

# Artec|E+ 48U
libusbscanner 0x0003 0x05d8 0x4003 0x0000 0x0000 0x00 0x00 0x00 0x00 0x00 0x00 0x00000000

The 0x05d8 entry is the vendor, which is correct, but the product is 0x4003 (not 0x4005 as in your case).
Its only a guess really, but it may be worth editing this file to reflect your product entry.

The other thing is that you need to make sure your artec_eplus48u.conf file is correct and contains the path to the firmware file which you need from your installation disc. Read carefully FIRMWARE FILE and CONFIGURATION from here:
http://www.sane-project.org/man/sane...plus48u.5.html

Memorex is not really mentioned, so I guess your scanner is a 'rebadged' Artec

I hope this helps,
tobyl

Thanks tobyl for your help. I was able to get it working. For reference purposes this is what I had to do:

1. Get the firmware file from the Windows installation disk - Artec48.usb
2. Edit /etc/sane.d/artec_eplus48u.conf. Find the Memorex section (usb 0x05d8 0x4005). Change the filepath for the firmware file (option artecFirmwareFile <pathname>/Artec48.usb), and also make sure to add this line:

option ePlusPro 0

Without this line the scanned images look corrupted.

That's it. Here's a link that shows you how to do it as well.

hi, i followed the steps and did it right, i think.
cept when i go to applications>graphics>xsane image scanner,
i get no devices available
but sane-find-scanner shows this

# sane-find-scanner will now attempt to detect your scanner. If the
# result is different from what you expected, first make sure your
# scanner is powered up and properly connected to your computer.

# No SCSI scanners found. If you expected something different, make sure that

but scanimage -L shows this
scanimage -L

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
which came with this software (README, FAQ, manpages).
thanks

i did as noted on here
https://help.ubuntu.com/community/ArtecEplus48uConf

Hi matchstich, could you give some more info,

which distibution and version are you using? (you might like to edit your lq profile)
which kernel? (uname -r)
what is the exact model of your scanner?

Also, did you modify the product id and path to the firmware file (that you copied to your sane.d directory) in the conf file?
Do you get any further running the commands as root?
Can you post the output of lsmod?

Ok, well I am not an Ubuntu user, but I guess if you post in a Slackware forum you must be really stuck, so I will make a couple of suggestions.

First, make sure you know where your sane.d directory is. I guess it is /etc/sane.d as the instructions you followed indicates this

(it also means the artec_eplus48u.conf file on your system is generic, not tailored for Ubuntu, as the default path in the file is given as /usr/share/sane.d/)

You have not edited the file artec_eplus48u.conf correctly.

usb 0x05d8 0x4005 has two entries in this file, and your entry is the second one, so it will probably not get found, so comment out (with #) or remove the first section that refers to this usb 0x05d8 0x4005 string.

Also if it still doesn't work, try the command scanimage -L as root. ( I think you use sudo for that on your distro) - this will test whether there is a permissions problem.

My scanner is different, but I have the sg module loaded, which I noticed you do not. So you may have the support built in to your kernel, otherwise you may wish to try "modprobe sg" as your sane-find-scanner output suggested:

# No SCSI scanners found. If you expected something different, make sure that
# you have loaded a kernel SCSI driver for your SCSI adapter.
# Also you need support for SCSI Generic (sg) in your operating system.
# If using Linux, try "modprobe sg".

This may also require root permissions.

good luck

never could get the scanner to work in 6.06 lts.

upgraded to unbuntu 7.04 followed the directions again.

now it opens but when i click on scan

all i get is a grinding sound like a gear is stuck.

any one have any ideas?

thanks

Is there a lock switch? I read somewhere that you sometimes have to lock and unlock again.

tobyl

ok, i tried that. same problem. grinding sound.
thanks

maybe something is wrong with it. cept it did work before in windows.

question: do i need to download any thing for the mem48 to work?

i searched every where but every one is saying they got it working just by following the directions about putting the firmware from the windows install disc in sane.d.

Hi there - here's my config. I can currently scan images using my scanner.

The relevant section in /etc/sane.d/artec_eplus48u.conf

Quote:

# Since the Memorex Mem48U uses a different product id, we add
# another usb section here.
usb 0x05d8 0x4005
option artecFirmwareFile /usr/share/sane/artec_eplus48u/Artec48.usb
option vendorString "Memorex"
option modelString "MEM 48U"

Make sure that this is the only section that refers to the scanner. I had previously mentioned that "option ePlusPro 0" is needed, but it seems that this is no longer the case. Perhaps it's due to an upgrade to sane, the version I'm using now is 1.0.18

Also verify that the firmware is in the right place and is the correct file. Here's mine (note the file size):

Quote:

yuchai@livingroom:~$ ls -al /usr/share/sane/artec_eplus48u
total 8
drwxr-xr-x 2 root root 24 2007-05-27 01:13 ./

-rw-r--r-- 1 root root 8192 2005-12-17 15:20 Artec48.usb

ok, i went back to the install link. it said something about installing the sane drivers.
that i didn't do. not sure how to do that.

anyhow, i changed the line in etc/

to

# artec_eplus48u - SANE Backend configuration file

i am confused by this. because the directions said to have the following

# Since the Memorex Mem48U uses a different product id, we add
# another usb section here.

to look like this:

# Since the Memorex Mem48U uses a different product id, we add
# another usb section here.

usb 0x05d8 0x4005

#
# Path to the firmware file
# This file comes with the Windows driver
# The scanner won't work without it
#

option artecFirmwareFile /etc/sane.d/Artec48.usb
option ePlusPro 0

but now, when i do

ls -al /usr/share/sane/artec_eplus48u

i get no such file or directory.
