Buyers should compare the documented capacity with their own typical job size rather than treating a large tray as evidence of long-term reliability.

It also matters when evaluating the feeder, because its 70-page capacity is a loading specification rather than a tested throughput or durability result.

Job structure therefore belongs alongside the page total when discussing the rated interval. A generic 30,000-page statement loses that context.
