• L1: Lead edge deviation at 200% magnification
• L2: Lead edge deviation at 100% magnification
• RRC-A = 4.7222 x (L1 – L2)
• RRC-B = 7.2202 x L2 – 3.6101 x L1
5 Using the ten keys, input the values of RRC-A and RRC-B given
by the expressions shown above. For input procedure see 3).
6 Take copies at 200%, 100% and 50% magnification and check
the deviation difference at each magnification is less than ap-
prox. 1 mm.
If the difference is larger than 1 mm, repeat step 3 to 6.
7 Take a 100% copy to check the image loss for 4 mm or less. If
the image loss is larger than 4 mm, change the content of
RRC-B so that the range of the image loss is 3 mm or less.
Note: The image loss value adjusted as described above is
the image loss value adjusted in Simulation 50-01,
and not the final value.
8 Set a scale and an A3-size(11" x 17") blank paper on the
original table as shown in the figure.
9 Operate the scrol display key to set to the void adjustment mode
of the LCD.
F Take a copy. Type a value for adjusting the end void area of the
full-size copy so that, measured with the scale image, the solid
edge is 1 ~ 4 mm away from the paper end.
The key operation → → PSW provide a copy and sets
the input value. The input value of "1" corresponds to 0.2 mm in
void area. Larger input value provides larger void area.
