In other words
replave most of the electronics in the printer until
the fault appears to go way. Without knowing what as actually
fialed, without knowing why it was cured,
And this is suypposed to be a sensible method of
fixing soemthing???
For the intended target audience, for their tradeoffs? Yes, actually,
it is. They are mostly service-orgnaization staff, many of them
comparatively poorly trained, and are - or at least should be -
optimizing not for least parts replaced or some such, but for least
time until the customer has a working printer again.
Right. I always think of it as the difference between a service manual and
a repair manual - the latter's more about actually fixing the fault, and
the former's aimed more at minimizing downtime for the customer.
