5. Refer to the table below and modify SP2152-xxx according to the measurement of X in
order to have the same density at the top edge and the bottom.
X mm Color SP2152-xxx Set to
Black 030, 031
Magenta 094, 095
Cyan 034, 033
152 ~ 163
Yellow 098, 097
Black 029, 030
Magenta 093, 094
Cyan 035, 034
141 ~ 152
Yellow 099, 098
Black 028, 029
Magenta 092, 093
Cyan 036, 035
130 ~ 141
Yellow 100, 099
1.000 ~ 1.165
* Increasing this SP value will
increase the toner density at the
rear (top) edge.
6. Turn the main power off/on. (The modified SP value will not take effect if the power is
not turned off/on.)
7. Print the same test pattern and check the density at the top and bottom edges.
8. Repeat steps 5 – 7 until the density at the top and bottom edges becomes even. If the
desired effect cannot be achieved with the SP set to a value between 1.000 and 1.165,
adjust the co-efficient value at the bottom edge by referring to the table below which
shows the SP values with the measurement of Y.
Y mm Color SP2152-xxx Set to
Black 001, 002
Magenta 065, 066
Cyan 063, 062
152 ~ 163
Yellow 127, 126
Black 002, 003

Cyan 062, 061
141 ~ 152
Yellow 126, 125
Black 003, 004
Magenta 067, 068
Cyan 061, 060
130 ~ 141
Yellow 125, 124
0.875 ~ 1.000
* Increasing this SP value will
increase the toner density at the
front (bottom) edge.
