Scanner fails to work with hpaio: I/O Error

[ygriffin]

Hello!

I'm trying to scan with simple-scan document scanner, but it fails. It's weird though. When I start up the scanner and immediately hit the scan button, it succeeds and scans one page. The next page always fails. It also fails if I do not press the scan button immediately. An popup appears:

Code: Select all

Failed to scan
Unable to connect to scanner

I can scan with Gimp if I use airscan. If I use hpiao I get the message:

Code: Select all

Failed to open device 'hpaio:/usb/Deskjet_3630_series?serial=CN7414H46X0659': Error during device I/O.

Don't know where to go from here ... Any help appreciated as it would be great to use simple-scan ...

Here some information about the setup:

I figured that I can start simple-scan from the command line with:

Code: Select all

simple-scan airscan:e0:HP

In this case it works.

Also when I start simple scan, I just figured out now, there is a selection option for the eSCL driver. It works like this.

Two things:

1) It is very slow ... I had it working with a linux mint installation and it was much faster ... don't know now which driver was used in mint.

2) how can I select the working "driver" as default?

Can you try Xsane? It probably gives you two scanners to choose, which of one is valid, you have try both.
