CAUTION: If the off-center adjustment is not completely, there's a

possibility to have the following problem when large size
paper (example: 13 * 19 inch size) was fed from LCT.
A: Registration Shift
B: Mechanical Vignetting

If the center is shifted greatly, “Color Shift” or Mechanical Vignett-
ing” may occur as the figure above.
In this case, it is necessary to do the following mechanical adjust-
ment.
Normally, Off-center adjustment is done by image processing using
CIS function. To check the mechanical off-center position, CIS
function needs to be turned off.

2) Select SW1 and change the value “1” to “0”.
3) Press [EXECUTE] key to print out for each paper feed tray.

4)

Check the void area of the adjustment pattern and check the
“Off-center” shift amount (A-B).
“A-B” is over 3mm: Move to Mechanical Adjustment 1
“A-B” is less than +/-3mm: Move to Mechanical Adjustment 2
“A-B” is less than +/-2mm: SW1 “0” to “1” for auto adjustment.

When shifted over +/-3mm.
