1). The new e4508LP uses the heat of the fuser to decolorize the blue toner to clear. The seperate RD30 erasing device is still available and presents a few advantages.
2). The MSRP does not include the seperate RD30 erasing device nor is it needed.
3). Not yet available.
4). Not yet available but probably.
5). Not yet available.
6). Regular 20 lb bond paper works fine. 28 lb bond paper will produce a better erase.
7). 45 cpm is the speed of black only. 35 cpm is the speed of the erase function as extra heat needs to penetrate the sheet of paper to get a good quality erase.
