With the TMA slide adaptor on the Scanjet 4570c does not work properly when : scan source = TMA negatives<br>--> [hp5590] Top X (0) + pixels X (4292) exceedes max X 169<br>xscanimage reports: Failed to start scanner: Invalid argument<br>
<br>In fact with the TMA adaptor in place even choosing: scan source = flatbed after you did a source=TMA<br>causes the carriage to ram into the stop. You have to power cycle the scanner to be able to get a source=TMA to properly work. <br>
So avoid source=TMA, choosing source=flatbed even with the TMA adaptor plugged in will work fine.<br><br>Evidently there is some problem with the source = TMA.<br><br>source=flatbed<br>line art, color, and gray = working<br>
resolution 100 to 2400 = working<br><br>source=TMA negatives or TMA slide<br>fails in all modes, ramming the carriage against the stop <br>
<br>I will use VMware + wireshark again to monitor my WinXP virtual
session and see what protocol is being exchanged when source = TMA. It
maybe that I can fix the driver, but I suspect it will be more
extensive changes. Let me look at what it takes to fix it. If it
gets too involved I will submit the current patch with the caveat
source=TMA fails, and work on fixing support for TMA later.<br><font color="#888888">
