<Color Deviation Correction Procedure>
There are 2 methods to correct a color deviation; using the "Test pattern 63" (correction method 1)
and using the "Test pattern 64" (correction method 2). Correct in either way of these methods.
Correction method 1
(1) While pressing the digital keys [0] and [5] simultaneously, turn the power ON. → (Adjustment Mode)
(2) Print out the test pattern and correct the deviation amount of the 1st page. Use the image position
of magenta (M) as a reference for correction. The image positions of yellow (Y), cyan (C) and black
(K) must be corrected with this reference.
a. Select A3/LD size. Key in “63” and then press the [FAX] button. → 2 pages of test pattern are
printed out.
b. Check the image of the 1st page and specify the color to be corrected.
c. Key in the code “417” and press the [START] button.
d. Key in the sub code of the color to be corrected and press the [START] button.
Sub code 0: Black (K) 1: Cyan (C) 3: Yellow (Y)
e. Key in the adjustment value and press the [ENTER] or [INTERRUPT] button.
Notes:
1. When the value increases by “1”, the image shifts toward the trailing edge of the paper by
0.0423 mm.
2. Adjust the image positions of black (B), cyan (C) and yellow (Y) to align the leading/trailing
edge of each image. If both leading and trailing edges are not aligned, adjust to uniform the
deviation amount of each edge.
(3) Print out the test pattern and correct the deviation amount of the 2nd page. Use the image position
of magenta (M) as a reference for correction. The image positions of yellow (Y), cyan (C) and black
(K) must be corrected with this reference.
a. Select A3/LD size. Key in “63” and then press the [FAX] button. → 2 pages of test pattern are
printed out.
b. Check the image of the 2nd page and specify the color to be corrected.
