(Solved) Top stacker available for 8000?

[oxident]

Hi!

I'm a little bit confused. The official HP datasheet lists the Top Stacker (CZ320A) as an available accessory for every Pagewide XL starting with the 4500. But on some dealer's sites, it isn't listed for the 8000.

Does anyone know if the 8000 can also be equipped with a Top Stacker?

EDIT: Finally got a response from my dealer. Top stacker is available but as it limits the speed to 12 A1/D pages per minute, it's rather useless for the 8000s.
