c. Manual Registration Adjustment
Registration adjustment is normally
performed in automatic mode. This
adjustment is a mode that performs fine
adjustment of the result of the automatic
registration adjustment. Note that it does not
reduce variations in the registration position.
Note:
This machine has a “Face-up
feeding” function, in which case the
document is fed into the machine
from the trailing edge. In this
“Manual Adjust” mode of the service
tool, do not make a mistake because
the edge that feeds into the machine
first is defined as the leading edge.
“Face-up feeding”

Operation Procedure
1) Load the scale parameter adjustment
sheet the same as for scale parameter
adjustment and scan the image. However,
set the size to "Auto Size".
Note:
Always set to "Auto Size" when
performing "Face-up feeding"
adjustment.
2) Check the position of the trailing edge on
the topside of the screen.
3) Change the adjustment value by directly
entering the value into the data box or by
using the scroll arrows.
This additional change value is added to
the value previously set by the automatic
adjustment.
For example, if the value is already [0.1],
enter [-0.9] if you want to add 1mm, or
enter [1.1] if you want to subtract 1mm.
4) After entering the values, click the [Set] button.
5) Scan the image again and check the position.
