A. Entering the simulation mode
Simulation is hereinafter described as SIM.
Perform the following procedure to enter the SIM mode.

B. Canceling the SIM mode
When the clear all key is pressed, the SIM mode is cancelled.
When the interruption key is pressed, the process is interrupted and the
screen returns to the sub code entering display.

and check the operation.
Note:If the machine is terminated by a jam error or paper empty during
copying in the adjustment by the SIM, recopying is required.
2.Copier adjustment
A.Mechanism section
Note: If a jam error or paper empty occurs during copying in the
adjustment by the simulation, the image data are not saved, and
therefore recopying is required.

(1) Image position adjustment
a.OC image lead edge position adjustment (SIM 50-1)
Note:In advance to this adjustment, the sub scanning magnification ratio
adjustment must be performed.
1) Set a scale on the OC table as shown below.
2) Make a copy.
3) Check the copy output. If necessary, perform the following
3) Check the copy output. If necessary, perform the following
adjustment procedures.
4) Execute SIM 50-1.
5) Set the OC lead edge position set value (PHOTO indicator ON) to [1]
5) Set the OC lead edge position set value (PHOTO indicator ON) to [1]
The OC image scanning start position is shifted inside the document
edge.
edge.
6) Set the 1st tray lead edge void adjustment value (TEXT indicator
ON) * to [1]
The lead edge void becomes the minimum.
7) Set the 1st tray print start position value (AUTO, 1st tray indicator
ON) to [1] and make a copy.
The print start position is shifted inside the document edge.
8) Measure the image loss R of the copied image. Enter the set value
of the image scanning lead edge position (PHOTO indicator ON)
again.
again.
•1 step of the set value corresponds to about 0.1mm shift.
•Calculate the set value from the formula below.
R/0.1(mm) = Image loss set value
•Calculate the set value from the formula below.
R/0.1(mm) = Image loss set value
<R: Image loss measurement value (mm)>
Example:
4/0.1 = 40 = about 40
Note:If the set value is not obtained from the above formula, perform the
fine adjustment.
