MX-RP19  ADJUSTMENTS  4 – 6

2) Enter the SIM 50-6 mode.

*

Item A, B: When the adjustment value is increased, the scan 
timing is delayed.

*

Item C - H: When the adjustment value is increased, the image
loss is increased.

*

Item A - H: 1 step = 0.1mm change

NOTE: When [CLOSE] key is pressed in this simulation mode, the

machine goes into the normal operation mode. Under this
state, copy check can be normally performed. When the
system key is pressed, the machine returns to the simula-
tion mode.

1) Set the lead edge image loss adjustment values (LEAD EDGE

(SIDE1/SIDE2)) on the front surface and the back surface to the
following values.

(Standard set value)

LEAD EDGE(SIDE 1): 

20 Lead edge image loss set value (Front surface)

LEAD EDGE(SIDE 2): 

30 Lead edge image loss set value (Back surface)

(When the set value is increased, the lead edge image loss is
increased.)

(Change for change in the set value: 0.1mm/step)

2) Make a duplex copy in 100% in the RSPF mode. Check to con-

firm that the lead edge image loss is within 3.0 +/- 1.0mm on the
front surface and the back surface. The paper lead edge must
be aligned with the presumed image lead edge.

If the above condition is not satisfied, perform the following pro-
cedure.

3) Enter the adjustment value of SIDE1/SIDE2 with 10-key, and

press [OK] key.

Adjust so that the paper lead edge is aligned with the presumed
image lead edge.

SIDE1: Front surface lead edge scan position adjustment

SIDE2: Back surface lead edge scan position adjustment

(When the adjustment value is increased, the print image posi-
tion is shifted to the delaying direction for the paper.)

(Change for change in the set value: 0.1mm/step)

Perform the procedures of 2) - 3) until a satisfactory result is
obtained.
