5) Measure the end edge void area of each copy.
6) Calculate the average void area.
7) Calculate the void area adjustment value from the formula
shown below.
Current set value (99) –
current void area
(
mm
)
0.123
= Adjustment value (Decimal point rounded)
8) Set the adjustment value obtained in procedure 7).
(Decimal point rounded off)
9) With the document cover open, make several copies at
100%.
10) Measure the copy lead edge void area.
11) Measure the distance from the paper end edge to the copy
image lead edge of each copied papers (129% and 64%),
and calculate the average value.
(Not required for the models without zoom functions.)
12) Check that the void area is within the specified range.
Standard:
1
∼
3 mm
If the void area is outside the specified range, change the
set value of simulations 45 and repeat procedures 9) to
12).
When the set value is changed by "1," the void area is
changed by about 0.123 mm.
When the set value is made greater, the void area be-
comes greater, and vise versa.
(End edge void area adjustment) Paper feed tray mode
1) Press the paper feed unit select button to blink the manual
paper feed lamp and to set the machine to the rear edge
void adjustment mode in the manual paper feed mode.
2) Perform the end edge void adjustment in the manual paper
feed mode similarly with the end edge void adjustment in
the cassette paper feed mode.
