The scanner was repaired, then broke again then after much fighting with the scanner manufacturer, was repaired correctly.
That sounds like a PITA! Unfortunately with trade equipment there are few people who can service/repair them, and it’s often the case that only the manufacturer can provide servicing. At my old job we had equipment that would break down and the closest serviceperson isn’t in our city so we would have to wait 2 weeks or more (usually) for it to be fixed. The serviceman I’m thinking of though was very good at his job and always eager to see the equipment working properly, but he was always very busy and in-demand.
