Hi, we sell Toshiba in the UK. The current colour range can run with a two tiered counter already.
We used to sell the Kyocera range with this feature it seemed to be good and won us business, but lost us money in service.
When colour costs are dropping to 4p, the percentage of toner from the 4p is getting less. So to breaking this down into 3 tiers could seem marginal. But let say you could offer 1.5p for 2% coverage then 2.5p for 2-5% coverage and then 4p for above, you have now lost out on all those low coverage copies. Then any high colour coverage will eat into the 4p, so you end up making nothing. The only true way is to have the high end at 6/7p. But then you compete against this by telling the client its 4p across the board and they are happy. Unless everyone does this then its not worth it. Un less I'm wrong!!!
