I recently got an umax scanner that was going to trash.
The stepper motor controller chip seems to have burnt.
It's a TI, but that's quite all I know about the reference.
I mailed the umax support, but got no reply, I don't
think they care that much.
Anyone has an umax astra 2000P (maybe other refs have
the same board) and could tell me the IC ref of U3 on
the main board marked:
HAIO M/B 2000P (+SHUTTLE) REV:B P/No: 5100011-0003 9913

Cheers,
François.
