I have 6 MS810's. So far one imaging unit has lasted to 0% (200k) and I have had 2 more go at roughly 75% (50k). The one that lasted is a 250 pages/day printer but the ones that have gone at 75% are 600 pages/day printers.
Is this normal? I don't think that we are pushing the printers to hard, most print jobs are 2-3 pages.
