AR-BC260 SETTING AND ADJUSTMENTS 8 - 10
7) Set SIM 64-1 as shown below, and make a self print of cross
pattern on A3 paper.
A: 1
B: 1 to 5
D: 1
YMCK all color mode
8) Check the latter part of the A3 copy paper for any color shift in
the paper transport direction.
If there is any color shift, change and adjust SIM 48-6 FSM (L)
(Fuser roller speed) setup.
When the paper transport speed in the transfer section differs from
that of the fusing roller, color shift is generated on the latter half of
paper.
Especially when the paper transport speed of the fusing roller is
greater than that in the transfer section, color shift is often gener-
ated on the latter half of paper.
This is because paper squeezed by the transfer roller and the
OPC drum is pulled by the fusing roller.
The longer the paper size is, the greater the difference is in the
paper transport speed between the fusing roller and the transfer
section, resulting in greater color shift.
1) Enter the SIM 50-20 mode.
SIM 50-20
2) Select the A4 (11 x 8 1/2) paper feed tray.
3) Press the [EXECUTE] key.
The image registration adjustment pattern is printed.
4) Check the rough adjustment print pattern position and the fine
adjustment print pattern position of each color on the front and
the rear frame sides.
Check visually and use the highest-density area of each color
as the center, and regard it as the reading value of shift.
(If the fine adjustment print pattern is in the range of 0 ± 2 for
the scale of the fine adjustment reference pattern, there is no
need to adjust.)
If the above condition is not satisfied, change the adjustment
value and tray again.
5) Select the color mode adjustment item to be adjusted with the
scroll key. Change the adjustment value and to adjust.
When the adjustment value is changed by 1, the image posi-
tion is shifted by one pixel.
6) Set SIM 64-1 as shown below, and make a self print of cross
pattern on A3 paper.
