2.6 Correction of Color Deviation
OKICOLOR 8 is equipped with an array of I/D units which cannot be from
generation of color deviations. This mechanically caused color deviation is corrected electroni-
cally as shown below.
(1) Color deviations to be corrected
1
Color deviation in the X axis (Positional error of the LED head)
2
Diagonal color deviation (Positional error of the LED head)
3
Color deviation in the Y axis (Positional errors of the I/D units and light receivers)
(2) Method of correction Print out the preset color chart, compare the printed color chart by
the original color chart, and enter the amount of color deviation of each color from the
operator panel or from the host computer. OKICOLOR 8 calculates
correction values from the entered values and changes the write timing of each color
(cyan, magenta, and yellow) relative to black.
2.7 Transfer Control according to Environmental Changes (Room Temperatures and
Relative Humidities)
OKICOLOR 8 measures the room temperature and humidity by the room
temperature sensor and the room humidity sensor, calculates an optimum transfer voltage
according to the obtained environmental conditions and realtime-controls printing with the
optimum transfer voltage.
