I used to have a 2700 and it definately was write-white, The HE-NE laser
in mine was cranky and if it failed to start you would get all black pages
It also meant that it was poor at drawing narrow (1 pixel) black lines.

It had an amazing fuser section that had no rollers (Fused entirely with
infrared) A side effect of this was that the fused toner was always shiny
