frame sides.
Use the visually highest color density section as the center,
and measure the shift amount.
The front frame registration and the rear frame registration are
adjusted independently.
To check the image registration, therefore, check the front

MX-4101N ADJUSTMENTS 5 – 22
* Measurement of the rough adjustment pattern
Check that the color line is positioned in the plus direc-
tion or in the minus direction and judge the polarity from
that.
The center black line is scaled as 0, the first line mark
as 40, the second line mark as 80, the third line mark as
120. The interval between the rough adjustment marks
corresponds to 40.
(Example)
In the case of the figure, it is between 40 - 80 of the plus
polarity, and the measurement is "40”.
tion or in the minus direction and judge the polarity from
that.
The center black line is scaled as 0, the first line mark
as 40, the second line mark as 80, the third line mark as
120. The interval between the rough adjustment marks
corresponds to 40.
(Example)
In the case of the figure, it is between 40 - 80 of the plus
polarity, and the measurement is "40”.
* The actual shift amount is the sum of the rough adjust-
ment reference shift amount and the fine adjustment
shift amount.
Shift amount (correction value) = Rough adjustment
shift amount + Fine adjustment shift amount.
When calculating, be careful of the plus polarity and the
minus polarity.
(Example)
In the case of the figure, the total shift amount is 54.
Measurement value: 54 (= 40 + 14)
shift amount.
Shift amount (correction value) = Rough adjustment
shift amount + Fine adjustment shift amount.
When calculating, be careful of the plus polarity and the
minus polarity.
(Example)
In the case of the figure, the total shift amount is 54.
Measurement value: 54 (= 40 + 14)
Measurement value: -54 (= -40 - 14)
The shift amount from the adjustment reference position
is calculated for each of six kinds of adjustment items A
- F.
is calculated for each of six kinds of adjustment items A

b)
Adjustment value calculation
Add or subtract the shift amount calculated above to or
from the current adjustment value, and the result value is
used as the new adjustment value.
(When the shift amount (correction value) is plus)
Adjustment value = Current adjustment value + Shift
amount (correction value)
(When the shift amount (correction value) is minus)
Adjustment value = Current adjustment value - Shift
amount (correction value)
Add or subtract the shift amount calculated above to or
from the current adjustment value, and the result value is
used as the new adjustment value.
(When the shift amount (correction value) is plus)
Adjustment value = Current adjustment value + Shift
amount (correction value)
(When the shift amount (correction value) is minus)
Adjustment value = Current adjustment value - Shift
amount (correction value)
