HPLIP

HP PSC 2175, Ubuntu Hardy, I/O error scanning

Asked by Kevin Safford

Neither Xsane nor hplip recognise the scanner. When I try to scan there is a long pause, and then I get the message about I/O problems that others have reported. I have installed the latest hplip from sourceforge, and uninstalled and reinstalled Xsane, to no avail.

I installed Ubuntu last Friday (dual-boot with XP), and the scanner still works on XP, so no hardware problem. On Ubuntu, I can print but not scan. I've spent a long time trawling the forums, but nothing I've tried has worked. I'd really like to lose XP, but I need my scanner - can anyone help?

Output from hp-check -t follow. 2 warning - one about PDF printer not being installed through hplip, and one about SIP not installed or version not found. I guess I can ignore the first, but what about the second? What is SIP and how would I get it?

Thanks in advance

Kevin,

Run:

sudo tail -f /var/log/syslog

and then in another terminal run xsane, when you get the error go back to the syslog and post all of the output.

Thanks!

Okay that looks okay. Are you printing through a usb hub?

No, direct through a USB port at the back of the box.

hplip found the scanner today, and xsane is working.

I have no idea why this is; the only changes that I have made to printers are:

1. To give a desktop (non-privileged) user the right to manage printers.
2. To replace an almost-empty colour print cartridge.

I've installed all the latest updates as they come along, but I don't remember seeing anything printer-related in them.

Thank you Aaron, for the time you spent looking at my problem and giving me advice. It's a shame we didn't get to the bottom of it, but I'm happy it's working now, and am closing this problem. (And it scans really fast compared to how it ran under Windows.)

My joy was short-lived; it didn't survive a restart of the computer. I made no configuration changes to the printer setup, but now have exactly the same problem if I try to scan: a window appears telling me it is looking for a device, there is a long delay and eventually I get an I/O error message.

That looks okay. I've tested the PSC 2170 on an Ubuntu system and it does scan okay. This tells me that there is either a hardware or software install problem. Can you test on a windows system to be sure it's scanning okay?

Thanks.

Hi Aaron

Last time I tried (a couple of weeks ago), it scanned OK on Windows - see original post. I suspect it's an installation problem. I'm now getting printer-related errors when I try to run Wine. What would I need to do to uninstall completely and do a clean reinstall?

Hi Aaron

Yes, I can confirm that the scanner still works under XP. I'm running it from the same box - just booted into Windows. Useful exercise doing that - it reminded me how much I like the HP scanner, and how painful it is using Windows.

When I installed Ubuntu, I had the printer connected, and Ubuntu it picked up automatically, before hplip was installed. Could something be lurking in one of the cups configuration directories, that's preventing hplip from working properly? I don't know my way around the system well enough to know where to start looking yet - any pointers gratefully received.

Thanks

Kevin

Now solved (hopefully for good this time). Today update manager updated a string of packages, and following a reboot, Xsane launches OK.

Some more information:

I had to boot into Windows today, after which the scanner again failed to work when I booted back into Linux. I could get it to work only by powering off the scanner, and then powering it on again.

I hope this is useful to anyone with the same problem.
