Building a Factory Acceptance Checklist for a Printer
Is a video of a running printer a full acceptance test?

Agree a factory acceptance checklist before shipment and link it to the purchased configuration. It should document visible condition, functional checks and the specified sample output.
Define what is being accepted Identify the model, serial number, included accessories and software scope. Record agreed checks with the supplier and avoid substituting unrelated demonstration footage. State who reviews the evidence and how exceptions are resolved.
Keep a usable handover record Save check results, sample files, photographs and the final packing list. Confirm unresolved items in writing. Acceptance evidence should help installation and support later, not simply mark a sales milestone.
