AR-M550/M620/M700 SETTING AND ADJUSTMENTS 7 - 28
1) Go through the modes specified in Simulation 50-6.
(Leading edge image loss adjustment)
1) Set the adjustment values for leading edge image loss for the front
and back sides as follows:
(Standard setting)
Paper leading edge void: 3.5mm (DENA:35)
2) In SPF mode, make a duplex copy at 100% magnification, and
make sure that the leading edge image loss is 1.5 mm for both the
front and back sides. (Select duplex mode from the paper selection
mode as described in Simulation 50-6). (Enter "100" into the
(MAGNIFICATION) field, and then press the start key).

If an acceptable result is not obtained, do the following steps.
3) Repeat the process of changing the (SIDE1 & SIDE2) adjustment
values and then pressing the Start key until attaining an acceptable
level.

(The adjustment value should be changed in steps of 0.1 mm.)
(The timing in which to start reading the image should be deter-
