 |
|
Hello,
I've got an USB AiO device - HP Photosmart C5280. This printer is connected via USB to my server/NAS.
I have successfully configured CUPS and printing works over LAN on any computer.
However I cannot get scanner to work. It is detected by server:
| Code: | # scanimage -L
device `hpaio:/usb/Photosmart_C5200_series?serial=MY75FBC17F04XQ' is a Hewlett-Packard Photosmart_C5200_series all-in-one |
I use saned daemon to share it over network, however I tried xinetd as well, with the same results.
When I try to scan anything from server using `scanimage > test.jpg` command, it scans the page and saves it as JPEG image. This is great and means scanner is working properly.
So, let's switch to client. It has all backends disabled except 'net' and just single IP address is specified in its configuration. It detects the scanner as well:
| Code: | $ scanimage -L
device `net:192.168.1.2:hpaio:/usb/Photosmart_C5200_series?serial=MY75FBC17F04XQ' is a Hewlett-Packard Photosmart_C5200_series all-in-one |
When I try to scan anything, scanner seems to work as well. However when it goes to the end it freezes. It seems like data is not being send back from saned server to the client.
There is nothing in client logs. Just after some time I/O error shows in the console. In server logs found only this:

I have tried SaneTwain as well under Windows as client with the exact results.
Am I doomed to scan from server's CLI only?
