[SOLVED] Failed to start scanner: Invalid argument HPc6380

[theAdmiral]

I am trying to scan with an All-in-One HP c6380. I get the message:

Failed to start scanner: Invalid argument

when I press the scan button in the GUI. Could anybody help me decipher this, please?

Thanks

Hello,
Some commands to check with

# scanimage -L
# hp-setup
if you type hp- TAB TAB ,, there maybe others helping commands
May want to install sane / xsane

May need to look at the properties of command

I tried these. Sorry, but they didn't work. My programs hplip and sane/xsane are already installed. Other options listed did not prove helpful.

Does scanimage -L show the scanner?

If not, does it show the scanner when you run as root?

[theAdmiral]

[root@localhost Desktop]# scanimage -L
device `v4l:/dev/video0' is a Noname HP Webcam virtual device
[root@localhost Desktop]#

I got a message saying that the message is too short, so blahblahblah.

[smr54]

Ok, it isn't seeing your scanner. Note that it's only listing a video device, not a scanner.

Did you get the same result as root?

If so, I would try manually adding it with hp-setup. I would use the command line--if it's on the network, at, say, 192.168.1.10 then

hp-setup -i 192.168.1.10

If that succeeds, then I would try scanimage -L again and see if it lists the machine.

But, the printer is not on the network.

[smr54]

In that case, if it's a USB connection, run

lsusb

This will give you the bus and device number, and you need the leading 0's. For example, if you get something like

Bus 001 Device 001: ID 1234:1234 you'd use

hp-setup -i 001::001

(It might also work with just hp-setup -i -a with the a standing for automatic)

If it's a parallel port then

hp-setup -i -a -x /dev/parport0 (or whatever the device is).


ID xxxx:xxxx

I was unable to complete the suggestion. See link below for results, please.

Looks as if you were't root when you tried. It has to be done as root, or at least with root privilege.

I would remove the printer from cups if it's in there, and try again.

[theAdmiral]

I don't understand what that had to do with scanning. What was that supposed to accomplish? I tried running xsane again and running a scan, I got the same error message.

[scott32746]

Are you able to do any of the other functions ?

[theAdmiral]

I presume you are talking about printer functions, and the answer is yes.

[smr54]

The answer to your quite reasonable question is that hplip's drivers seem to help with getting scanning to work as well. I've never looked deeply into the reasons, just found that for me, at least, when scanning didn't work, reinstalling the printer with hplip fixed it.

[theAdmiral]

So, when you reinstall, do you uninstall everything and reinstall from scratch?
