I'm running Ubuntu 64-bit and I just installed a printer, the Epson Stylus NX110. Whenever I try to scan or print my computer powers off. There doesn't seem to be anything left over in my logs, (but that isn't saying much, because if something is left it probably doesn't have time to disk sync before the power off.)

I also attempted to scan within a Virtual Machine running Windows XP. Same issue.

This is probably a hardware issue from the symptoms. But it's really strange. What does Superuser say? Bad Motherboard? Bad Power Supply? Bad USB Drivers under Linux?

Here is some information about my system:

I know you said there was nothing in the logs, but which logs? Does dmesg show anything at that time? and where did you load the driver from - in other words, what driver is it? – Beel Apr 19 '11 at 18:18
The specific logs I've checked are /var/log/kern.1 /var/log/dmesg.1.gz /var/log/syslog.1 /var/log/messages.1. The driver used is the built-in it automatically installed, cups prompted me for a file, I used the one for Stylus NX115. – OmnipotentEntity Apr 20 '11 at 3:16
Have you tried reinstalling the driver? Here is a link I found that might help, although I have not used it myself: – Beel Apr 20 '11 at 5:18
Defective printer? – Justin Pearce May 4 '11 at 18:17
This is a possibility, but it works under MacOSX 10.5 on a different computer. It's also a possibility that it's an issue with my motherboard's USB controller or something like that. – OmnipotentEntity May 6 '11 at 15:15

First thing I'd try (if you're not already) is using a mains powered USB hub. Maybe the printer is pulling just enough power to knock your Motherboard or PSU over the edge.

I found that not all my USB ports on all my computers are the same. It matters very much WHICH USB socket (& port) is being used. If you have a modern USB connection, it gets worse, with USB3, etc.

I assume you've checked that it is not a cable, nor the scanner's problem?

AFAIK most printers have a self-test mode,independent of any connections anywhere else. We assume you've check that the scanner-printer is ok.

Generally I have two Linux systems on my computers. Usually only Win7 or Linux crashes. I've yet to discover how I can have two Win7 op systems on the one hard disk.
