Ricoh Aficio 401 400 400 http://www.ricoh-europe.com/product/copier/core.htm?category=bw&product=a401 us-ascii B hpijs I used the existing magicfilter filter for HP LaserJet 4, but changed resolution from 600 to 300. I have only made it print in 300dpi, and the marigins need adjustment. Printing mechanism is specified as "Dry Electrostatic Transfer System"
