Not free from dust, but completely silent in standby

A beautiful print: very small, attractive design, functional software for network and toner save mode, fast duplex.
However, the product description in two important ways is wrong:
1. "The guard and the built-in paper tray to prevent dust from getting on the paper and in the interior of the printer." No, that's not true. The paper tray is open to the rear and rises when setting the paper size in the paper tray on A4 (the likely most common setting) open the back of the printer!
2. "Noise emission in standby Overall I prefer 1 Star or More for false advertised dust. As you can about it span a piece of household foil is not so in the viewing area.
