SIDE2: RSPF adjustment for the back side
ALL: RSPF adjustment for both the front and back sides

4)

Select one of the cassettes that can be used to print SPF
adjustment patterns. (Multiple selection is not allowed.)

5)

Press the [EXECUTE] button, and the machine starts self-print
of SPF adjustment patterns.
* The screen shows a message indicating that the machine is

self-printing SPF adjustment patterns.
When self-print finishes, the next screen appears where you
can start SPF adjustments.

6)

RSPF adjustment patterns are loaded into the RSPF.

* By pressing the [REPRINT] button, you can return to the

cassette selection screen and have the machine self-print
SPF adjustment patterns again.

7)

Press the [EXECUTE] button, and the machine starts reading
SPF adjustment patterns (for the front side).
* The screen shows a message indicating that the machine is

reading and calculating SPF adjustment patterns (for the
front side).
The machine starts calculating the adjustment amount (for
the front side) after it has read the patterns for the front side.
After the machine has finished calculating the adjustment
amount for the front side, the next screen appears where
you can have the machine start reading SPF adjustment
patterns (for the back side).

• RSPF original leading edge adjustment (front side)
• RSPF original off-center adjustment (front side)
• RSPF original sub-scan magnification adjustment (front

side)
