I questioned why, when the spec say 20k pages, our image drum averages just over 10k pages per drum.
we got the this rather convoluted reply
The image drum specification of 20,000 is based on 3 pages per job, simplex ,A4.
If you do just 1 page jobs , simplex, A4 , you will get approx 12000.
If you do a mix of 1,2,3,4 page/job then you will get somewhere in between 12-20 K.
If you do double sided printing (duplex) the page count only counts 1 page but the drum count is doubled (as print is on both sides)
Also turning the printer off/on or opening closing the covers will use up the drum life but not count toward the page count .This is because the printer has to go through a warm up cycle which rotates the drums.
all I can say, is please quote me actual realistic numbers, not 'broaband' figures (maximaum spped will be 20 meg, but you will actually get 5.5 meg...),urumph
