I don't think this is true. I am running the latest bleeding edge
backend from
with my HP 7400c and I first thought that it had been corrected. But it
turned out to be true only after a reboot and subsequent scans performed
after the lamp had cooled off had the old problem: scanner stops halfway
through in a horrible noise which you have to stop by pulling the plug.
After switching it on again it pauses for 90 sec. before doing a correct
scan and so it does at all following scans - pausing 90 sec. that is. It
is only back to normal after a reboot.
