When analyzing the effects of cost reduction, there can be a difference in cost reduction effect, not because of
users in your company, but because of the amount of toner and paper annually used.

The chart below is a condition about general company and public company.

- The standard of output : The original cost of one sheet of A4 = 18 won,
- The original cost of toner for one sheet of A4 = black/white 30 won, color 140 won,
- The total cost of printout/A4 = black/white 48 won, color 158won,
- cost of printout = The original cost of paper * toner cost
- printout rate = black/white printout 80%: color printout 20%
* Reduction rate will increase much more when color printout rate is high.

· Standard: 30% of reduction of the amount of toner annually used and 20% of paper
