Adjustment flow
Follow the procedure below to proceed the Both Sides Adjustment.
A
Check the reference position of the print side
To judge whether a print position is misaligned, the required reference position adjustment must be
completed on this machine.
Before starting the Both Sides Adjustment, check the adjustment value of the reference position. If
necessary, adjust it.
There are the following adjustment items to be checked. To check them, on the [MACHINE] screen, select
[Adjustment] - [Machine Adjustment] - [Printer Adjustment].

does not support the [Scan Meas.] adjustment.)
-
Gap Adjustment: the method used for aligning both sides with correction of the back side
magnification and print position based on the front side ones (page 5-10).
-
Chart Adjustment: the method used for aligning both sides with correction of the magnification and
print position of both front and back side (page 5-15).
-
Zoom and Image Shift Adjustment: the method used for fine adjustment after Scan Measurement
Adjustment, Gap Adjustment or Chart Adjustment, or the method used when the amount of
misalignment between both sides is figured out (page 5-22).
