I support the recommended change of not SETTING the 'broken'
bit whenever the device 'knows' that the condition to be resolved
depends ONLY upon 'normal human intervention...' and NOT in
need of 'extraordinary (service) intervention...'. In other words, I
recommend that the 'broken' bit(s) remain, but by definition that
they are only SET when the device 'knows' (because of its
intrinsic error handling capabilities) that 'something beyond
normal human intervention...' is required to resolve the problem
(eg: service rep, key operator, etc). The 'broken' bit therefore
acts as a simple indicator of problem 'severity'.
I think this fits in with HP's approach as well, since they set the
broken bit for "Marker Supply Missing" which may be a more serious kind
of condition and require a more skilled person to fix.
