toner coverage vs yield vs price..

[inutelkamo]

any one knows the proper furmula for computing the price per page?
using the ff:
Toner Coverage computed by APFILL,
Toner Yield,
and Toner Price,

Any??

thx in advance

You may try ratio and proportion. 5% (for text only)/total yield = ?%(assuming you have images to print)/total yield = cost of toner/total yield

If you just assumed a standard 5-6% coverage, then you would just divide the toner cost by the yield and that would give you a price per page. If you need to assume a different coverage percentage, different than the manufacture, you could produce a linear graph that can shift in accordance to coverage. If you double the coverage, 5% to 10% than you would just have to double that price per page, because this is a linear function the yield would not matter since you created a starting point (assuming that the toner was a 20,000 page yield at say 6%). But there is one issue, you have to assume losses (waste toner), this you could do by weight. Weigh a empty toner bottle and a full toner bottle, subtract the two to find the toner weight. Then take the price of the toner and divide by the weight, this will give you price/weight units. Now when you go add toner, weigh the waste toner bottle and subtract the weight from your empty waste toner bottle. Now you know how much waste toner there is by weight, multiply the weight into your price/weight units and now you have to cost of the wasted toner.

If you want to be a real stickler, you could also change for developer assuming the yield of the developer. Developer is not cheap as you already know, especially that colour stuff.

You know, this would be a real cool computer application I could make. Hmm...

Do you have access to mykonicaminolta? They have what's called a C.L.I.C. Basically a fancy spreadsheet that has everything you need for determining CPC.
You can plug in several different variables into it....
