No, in this case, the error will repeat until I send a "request sense"
command to the scanner. The "suggest retry" is absolutely valid. But
my sense handler, right now, can't tell and reports success, so the
backend doesn't know it should first request sense and then retry.
Of course, I can just guess and always retry. But that is far from
efficient, especially since there is a 60-second timeout involved.
