The measurement value is multiplied with 10 to enter.

With the above procedure, the values of RRC-A and RRC-B in
SIM 50-1 are automatically calculated and set.By directly setting
the values (actual dimensions [mm] x 10) of IMAGE LOSS, DEN-A
and DEN-B, the lead edge image loss, the lead edge void area,
and the rear edge void area can be set.

By setting the image loss, DEN-A, DEN-B (actual dimension (mm)
x 10) and REAR LOSS (SPF) (actual dimension (mm)) directly,
the lead edge image loss, the lead edge void area, the rear edge
void area and the rear edge image loss (SPF) can be set.

Operation/
Procedure

1. Enter the adjustment value with the 10-key.

2. Press the [EXECUTE] key to set the adjustment

value entered in procedure 1.

When the set value is increased, the top margin is increased.
When the set value is changed by 1, the top margin is changed
by about 0.1mm.

Operation/
Procedure

1. Perform the 0C lead edge adjustment with SIM 60-

1/2. (To use the 0C lead edge void quantity.)

2. Set the image loss quantity (LOSS (RSPF)) to a desired value.

(0 - 99: 0.1 mm/step)

3. Adjust the original scanning start position (RSPF

(SIDE1)/RSPF (SIDE2)) so that the actual copy image loss
quantity is as specified in procedure 2. (0 - 99: 0.1 mm/step)

4. Adjust the rear edge void quantity (DEN-B). (0 - 99: 0.1

mm/step)

5. Adjust the rear edge image loss quantity (REAR LOSS (SPF))

when the SPF is used. (0 - 20 mm/step)

There are five input items of the copy lead edge adjustment;
LOSS (RSPF), RSPF (SIDE1), RSPF (SIDE 2), DEN-B, and
REAR LOSS (RSPF). Select the desired item with [

change the set value.

1. Image loss quantity setup value (RSPF ) --- (LOSS (RSPF))

Used to adjust the output timing of the image lead edge signal
(SCAN signal) after starting scanning of the original. (0 - 99:
Reference value 20)

2. Original front surface scanning start position adjustment value -

-- (RSPF (SIDE1))
Used to set the time from the start of original feed to reaching
at the exposure position. ([Front surface] (0 - 99: Reference
value 50)

3. Original back surface scanning start position adjustment value

--- (RSPF (SIDE2))
Used to set the time from the start of original feed to reaching
at the exposure position. [Back surface] (0 - 99: Reference
value 50)
