<EM>> After running out of options for trying to understand the interface, I
|
|
</EM><BR>
|
|
<EM>> decided to pull my scanner to pieces earlier this evening. Canon had done
|
|
</EM><BR>
|
|
<EM>> a good job with one-piece moulded plastic and unnecessary amounts of glue,
|
|
</EM><BR>
|
|
<EM>> but I got the glass off and removed the PCB cover without breaking
|
|
</EM><BR>
|
|
<EM>> anything. And yes, they've gone out of their way to cut corners.
|
|
</EM><BR>
|
|
<EM>>
|
|
</EM><BR>
|
|
<EM>> Findings:
|
|
</EM><BR>
|
|
<EM>>
|
|
</EM><BR>
|
|
<EM>> (1) LM9830 chip, courtesy of National Semiconductor (note: parallel port
|
|
</EM><BR>
|
|
<EM>> chip).
|
|
</EM><BR>
|
|
<EM>>
|
|
</EM><BR>
|
|
<EM>> (2) GL640 USB-to-parallel convertor. Docs are fairly inpenetrable, though
|
|
</EM><BR>
|
|
<EM>> I hoped someone here might have come across this chip before: it's a
|
|
</EM><BR>
|
|
<EM>> standard one used in printers, IIRC. Anyway, here's the link:
|
|
</EM><BR>
|
|
<EM>>
|
|
</EM><BR>
|
|
<EM>> <A HREF="http://www.genesyslogic.com/gl640ucb.htm">http://www.genesyslogic.com/gl640ucb.htm</A>
|
|
</EM><BR>
|
|
<EM>>
|
|
</EM><BR>
|
|
<EM>> (3) One other large chip (an SBT, SB61H1024AS-12), which looks like RAM,
|
|
</EM><BR>
|
|
<EM>> plus other small ones (I've noted numbers and taken photos of the PCB for
|
|
</EM><BR>
|
|
<EM>> posterity).
|
|
</EM><BR>
|
|
<EM>>
|
|
</EM><BR>
|
|
<EM>> So it looks like we're dealing with a parallel port scanner with a USB
|
|
</EM><BR>
|
|
<EM>> interface tacked on. Any suggestions as to where to start...?
|
|
</EM><BR>
|
|
<P>Look at the following project.
|
|
<BR>
|
|
<P><A HREF="http://hp4200-backend.sourceforge.net/">http://hp4200-backend.sourceforge.net/</A>
|
|
<BR>
|
|
<P>It does not use the exact same USB-EPP bridge, but they might be very
|
|
<BR>
|
|
similar, or perhaps, identical in function.
|
|
<BR>
|
|
<P>Good luck!
|
|
<BR>
