OT:scanning with scanimage and gocr

[Ryan Mann]

Hello.  I realize that this is off topic for this list, but 
people ask all kinds of Linux questions on this list, so I 
figured that it would be OK for me to ask this.  Has anybody 
successfully used Scanimage and Gocr to scan and read a 
printed document?  I  was trying to do this yesterday, but 
Gocr prints a  little bit of the document and some garbage. 
As an example of what happens, I'll tell you the steps that 
I go through then show you the result.
The commands are below.
scanimage --resolution=300 >test.pnm
gocr -i test.pnm -f ASCII
Heres what I get with the document.
(PICTURE)c(PICTURE) o ? E x T I o x B u (?) (?) (PICTURE)E T 
I (?) l

_r (?)(?)_ _ n(?)_(?)_ (?)  m(?)(?)(?)n (?).nn(?) ,_,n

What am I doing wrong?  I'm using Linux version 2.6.11.8 and 
Sane version 1.0.13.  Thanks for your help.

Hello,
I have also had very little success with this, and recieved similar results. 
I have also tried ocrad and also got the same. I don't know if it is the way 
the image is got, or if it is the OCR software that is the problem. I would 
also like to know if anyone can do successful OCR.
