Introduction

Sane provides a library and a command-line tool to use scanners under GNU/Linux.

Step 1: Check if sane supports your scanner

Check if sane supports your scanner

Step 2: Installation

Template:Codeline is available in the Template:Codeline repository so:

# pacman -S sane

Step 3: Configuration

Users that need to use a scanner should be part of the group Template:Codeline. Use Template:Codeline to add a user to a group:

# gpasswd -a username scanner
Note: You need to logout/login for this to take effect.

Now you can try to see if sane recognizes your scanner

$ scanimage -L

If that fails, check that your scanner is plugged into the computer. You also might have to unplug/plug your scanner for Template:Filename to recognize your scanner.

for HP hardware

For HP hardware you may also need to install the Template:Codeline package which is in the Template:Codeline repository:

# pacman -S hplip

Step 4: Firmware

Note: This section is only needed if you need to upload firmware to your scanner.

Get the firmware

Note: If you don't have an install CD, you might find the required software on the scanner manufacturer's website.

Extract the file from your scanner install CD

Firmwares usually have the Template:Codeline extension.

But it may also be in:

Install the firmware

Firstly you need to put the firmware someplace safe, it is recommended to put it in a subdirectory of Template:Filename.

Then you need to tell sane where the firmware is:

If the backend of your scanner is not part of the sane package (such as hpaio.conf which is part of hplip), you need to uncomment the relevant entry in /etc/sane.d/dll.d/hplip.

Step 5: Install some frontend(s)

XSane provides a GTK-based frontend to Sane. It is available in the Template:Codeline repository.

# pacman -S xsane

Other frontends exist, to find them you can:

Troubleshooting

Invalid argument

If you get an "Invalid argument" error with xsane or another sane front-end you probably need a firmware. See above for details.

Permission problem

If you see your scanner only when doing Template:Codeline you might get it working by adding your user to Template:Codeline group.

# gpasswd -a username lp

This is reported to work on HP all-in-one models (e.g., PSC 1315 and PSC 2355).

DBus problem

If you get following problem:

arguments to dbus_connection_send() were incorrect, assertion "connection != NULL" failed in file dbus-connection.c

Add Template:Codeline to groups Template:Codeline and Template:Codeline:

# gpasswd -a dbus lp
# gpasswd -a dbus scanner
