Problemas con scanner Benq 4300.

Postby sabrinalacolo on Fri Jan 24, 2014 8:50 pm

Hola a todos!

Les escribo para solicitar ayuda con la instalación de un scanner.
Hace poco instalé Linux Mint Debian Edition en esta PC. Antes utilizaba otra distribución de Linux, basada en Ubuntu y el scanner funcionaba sin inconvenientes.

El asunto es que en LMDE no lo reconoce, habiendo consultado entonces varias respuestas a problemas similares, por lo que comento en detalle todo lo que hice.
Se trata de un scanner marca BENQ 4300.

Al comienzo me tiraba un fallo que decía algo así: "Fallo al abrir dispositivo. snapscan libusb 005.002. Argumento no válido".

Busqué por Google y encontré que podía ser el firmware, así que lo conseguí (tengo el CD de instalación y logreé rescatar el .bin), cambié los archivos como se indicaba, y ahora el mensaje es:
"Fallo al abrir dispositivo. snapscan:libusb:005:002. Error durante E/S de dispositivo".

Si intento abrir el programa XSane por consola, me devuelve estos mensajes:

user@user ~ $ xsane
Fontconfig warning: "/etc/fonts/conf.d/53-monospace-lcd-filter.conf", line 10: Having multiple values in <test> isn't supported and may not work as expected

user@user ~ $ sudo xsane

Fontconfig warning: "/etc/fonts/conf.d/53-monospace-lcd-filter.conf", line 10: Having multiple values in <test> isn't supported and may not work as expected

user@user ~ $ sudo simple-scan
Fontconfig warning: "/etc/fonts/conf.d/53-monospace-lcd-filter.conf", line 10: Having multiple values in <test> isn't supported and may not work as expected

** (simple-scan:3728): WARNING **: scanner.vala:801: Unable to get open device: Error during device I/O


El scanner Benq es reconocido como FlatbedScanner 23 (en la anterior distribución que tenía lo reconocía así y funcionaba):


user@user ~ $ 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 kernel SCSI driver for your SCSI adapter.

En la carpeta --> /usr/share/sane/firmware --> ahí puse el firmware para el modelo del scanner Benq 4300.

luego en etc/sane.d/snapscan.conf edité lo que marco en negrita:



#------------------------------ General -----------------------------------

# Change to the fully qualified filename of your firmware file, if
# firmware upload is needed by the scanner
firmware /usr/share/sane/firmware/20B0V113.bin --> le quité las ## y agregué el .bin del firmware que antes guardé en la otra carpeta.

# If not automatically found you may manually specify a device name.

# For USB scanners also specify bus=usb, e.g.
# /dev/usb/scanner0 bus=usb --->> probé poniéndote y quitándole la# que tenía adelante.

# For SCSI scanners specify the generic device, e.g. /dev/sg0 on Linux.
# /dev/sg0

¿Alguno podrá guiarme para que el scanner funcione?

Desde ya muchísimas gracias,
