"Original HP testing on Canon's prototype showed the print engine to
be very unreliable with an MPBF (mean pages between failures) of only
250 pages. The original engine required a complete redesign."

No chyba ze to oznacza zaciecie co 250 stron ... niezly wynik :-)

Swoja droga - ze im sie nie chcialo opracowac wlasnego mechanizmu ?

No i ... co sklonilo firmy od kopiarek do dolozenia do nich lasera, i
czemu nie osiagnely takiego sukcesu jak HP ?
No dobra - Xerox mial duze laboratoria i szerokie zainteresesowania
