1.5.2 Color Registration Control Procedure 1: To Correct Out-of-register colors
on A4/LT -sized Paper with Test Print Pattern 68 (05-68)
(1) Enter adjustment mode [05] and print out the test print pattern to correct out-of-register colors.
• Use steps (a) to (b) to print out the test print pattern.
(a) Select A4/LT-sized paper.
(b) Enter a code corresponding to a desired test print pattern. Press the [FAX] button.
• Print out any of the following test print patterns in the table below.
[05] code Test print pattern
Paper
size
No. of copies
to be printed
05-69 Grid pattern (for identifying out-of-register colors) A4/LT 4
05-68 Test print pattern 68 (ladder pattern) A4/LT 4
* Use code 05-69. The grid pattern will be printed on the entire copy, with all toner colors (C, M, Y and
K) overlaid. Check the printed grid pattern (or whether the toner colors are accurately overlaid) to
discover out-of-register colors on the entire copy.
* Jot down a "page number" and "paper feeding direction" on the printed test print pattern beforehand.
This facilitates identifying out-of-register colors in the subsequent adjustment.
* Refer to procedure (2) of "1.5.1 Color Registration Control Procedures 1: To Correct Out-of-register
colors on A3/LD-sized Paper with Test Print Pattern 63 (05-63)" for further information regarding the
test print pattern sample and adjustment procedures.
(2) Enter adjustment mode [05]. Change the values for codes [953 to 956] to correct out-of-register colors.
• Align 3 toner colors (Y, C and K) with magenta (M). First, change the value for code 05-953 and correct out-
of-register colors on the first page of the test print pattern. Next, print out the 4 copies of test print pattern
again. Change the value for code 05-954 and correct out-of-register colors on the second page. Similarly,
print out the 4 copies of test print pattern at each time of correction. Change the value for code 05-955 and
correct out-of-register colors on the third page, and change the value for code 05-956 and correct out-of-
register colors on the fourth page.

* If the set value is increased by 1, the print position of the color will be shifted for 0.0423 mm toward the
trailing edge of the paper. (For instance, if the value for code 05-953-1 is increased by 3, the print position
of cyan will be shifted for 0.1269 mm (0.0423mm x 3) toward the trailing edge of the paper. This
correction will affect all pages.
