Canon's approach of making the drum part of the toner cartridge effectively increases the cost of toner, since you can't refill without also replacing the drum and various other things. On the other hand, it means that most of the critical parts get replaced every time you refill, which minimizes the need for maintenance and makes certain important classes of repairs trivial. It's like any throwaway product: much more convenient and fewer hassles, if the quality's good and you can afford it. The Canon catridges (so far) are of quite good quality, and they are eminently affordable for most purposes. (One would not choose a printer this size for huge bulk print runs anyway.) I trust that this part of the original message is more-or-less verbatim from DEC, since it is skilfully phrased to make people think the Canon engine requires frequent non-trivial maintenance. Since the drum is part of the cartridge, and replacing the cartridge is trivial, the ominous tone of the phrasing is highly misleading. Sounds to me like DEC has come up with another turkey. Canon did it right. Henry Spencer @ U of Toronto Zoology {allegra,ihnp4,linus,decvax}!utzoo!henry
