1.5.2Color 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	No. of copies
			size	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.

Color	[05] code	Subcode	Value recommended	Acceptable value range
Y (yellow)		3
M (magenta)	05-953	2	125 to 131	118 to 138
C (cyan)		1
K (black)		0
Y (yellow)		3
M (magenta)	05-954	2	125 to 131	118 to 138
C (cyan)		1
K (black)		0
Y (yellow)		3
M (magenta)	05-955	2	125 to 131	118 to 138
C (cyan)		1
K (black)		0
Y (yellow)		3
M (magenta)	05-956	2	125 to 131	118 to 138
C (cyan)		1
K (black)		0

*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.
