Ink Yield Targets
Ink consumption is directly related to the following 6 variables:
Variable elements
Amount Consumed
Low High
Printing Speed High speed Low speed
Temperature Low High
Image Area Small Large
Paper Low absorbency High absorbency
Copies / Original High Low
Drum size Small Large
The number of copies per cartridge can be estimated using the following formula.
A x Y
X: Copies per cartridge
A: Amount of ink the cartridge
Y: Average number of copies per original
Z: Ink consumed per copy
B: Ink consumed per ejected master
X =
B + (Y x Z)
A: Amount of ink per cartridge
For the C264, this is 600g, A=600
Z: Ink consumed per copy
The following matrix shows ink consumption (gram) per one square meter (m

Standard mode)
Z = 4.1 x (0.21 x 0.297) x 0.06 = 0.015g

Sample Ink Yield Calculation results (normal temperatures, 90cpm, A3 drum, A4 paper, 6% chart)
C/O = 30 X = (600 x 30) / {4.8 + (30 x 0.015)} = 3,429 copies
C/O = 50 X = (600 x 50) / {4.8 + (50 x 0.015)} = 5,405 copies
C/O = 100 X = (600 x 100) / {4.8 + (100 x 0.015)} = 9,523 copies
C/O = 200 X = (600 x 200) / {4.8 + (200 x 0.015)} = 15,385 copies
