Who is the "customer" for the image manufacturer?

I received a call from an old trading company (O's distributor) after a long time.
It was a business inquiry,
He said, "An equipment manufacturer delivered a system using Company C's image processing equipment to a customer. However, he left on a business trip for another matter without setting up the system. The customer requested support for the start-up work, but could your company handle it?
The question was, "Can your company handle it?
I had never touched Company C's equipment, and I was not about to pick up a chestnut from the fire by starting up an image processing system that had been handled by another company.... If there was a guarantee that the system would start up, I wouldn't mind doing it, since it was only a matter of man-hours, but it seemed that the experiments were left to the contractor, and I was suspicious just by listening to them.
In this case, it is true that there is a problem with the equipment manufacturer who did not start up the equipment properly, but I also feel that there is a problem with the customer who is just watching with their fingers crossed.
(1) The end users themselves do not make a decision on whether the equipment is usable or not at the stage of introduction. If they had been able to do so, the system would have gone into operation immediately after delivery.
(2) Even considering future operations, image inspections will be difficult unless the "field" is willing to do something about it on their own.
There seem to be two types of "imaging."
(1) Imaging equipment set up by the equipment manufacturer with the equipment manufacturer as the customer. Since handling is also a set, the result is for a specific sample.
(2) End-users are the customers, and the end-users themselves set up the image processing equipment. High versatility is required because the use of the equipment is indefinite. In addition, it must be "usable" because end-users can configure it themselves.
I think FI is a rare image processing system that is targeted at end-users (and "onsite" users). Since the end-users themselves conduct their own preliminary evaluations, it is unlikely that they will not be able to set up the equipment after it is completed (by themselves).
