1.Open the stock record for the toner required. Go to the Contracts tab on the stock record. Here is where to enter the expected coverage that equals to one A4 page, ie. 5%.
2.Against the meter line in the Meter Setup tab of the contract, enter the relevant ratio. The amount of toner usage can be adjusted to each tier. For example, if expected coverage for 1 A4 page is 5%, A4 Ratio for Tier 1 is 1 (meaning 1 page at 5% coverage). Similarly the tier 2 meter may count for 1.2 pages (at 5% coverage) and tier 3 meter may count for 1.5 pages when calculating usage, etc.
