Finally, past midnight, the Mustek scanner seems to be responding. Now the<br>
|
|
problem is that the image quality leaves quite a lot to be desired -<br>
|
|
whenever I use color mode, the image looks gray with lines running<br>
|
|
perpendicular to the direction of the scan ( horizontal lines, if you will)<br>
|
|
<p>
|
|
To get it to work so far, I did the following:<br>
|
|
<p>
|
|
( I am on Linux 2.0.30 using an ncr 810 card )<br>
|
|
<p>
|
|
Edited the ncr53c8xx.c with the guideline "to fix errors, eliminate the<br>
|
|
error checking!" : <br>
|
|
<p>
|
|
1. I was getting "extraneous data discarded" error, so I just commented<br>
|
|
out the error checking somewhere near the line 4509. The entire block<br>
|
|
beginning "if (cp->xerr_status != XE_OK)". I don't have a clear idea of<br>
|
|
what this does, I imagine it's necessary for something... <br>
|
|
<p>
|
|
2. I was getting another error "ncr dead?". For this, I changed line 5323<br>
|
|
from "if (np->latetime>10)" to "if(np->latetime>100". Once again I'm not<br>
|
|
sure what this did. I was guessing that 10 was in seconds, but it seems<br>
|
|
like after the change to 100 it completes scans that take way more than<br>
|
|
100 seconds. This 100 sends was picked completely out of the blue, but it<br>
|
|
seems to improve things...<br>
|
|
<p>
|
|
Now if only comebody could help me fix this image quality problem...<br>
|
|
<p>
|
|
Any comments would be highly apreciated. If this doesn't work ( SANE, that<br>
|
|
is ) I will officially declare Mustek Paragon 800SP ( == 8000SP ) a total<br>
|
|
piece of crap that only works on Windows 95 and only with their card.<br>
|
|
<p>
|
|
Thanks in advance for any help,<br>
|
