When you replace one of the following parts, perform sensor position adjustment and sensor
sensitivity adjustment as shown below.
Parts replaced
SA Main PCB
SA Adjust Sensor U
(transparent sensor)
SA Adjust Sensor L
(Reflective sensor))

(1) Sensor position adjustment (Factory mode)

After entering Factory mode, adjust the following submenu items:
For details, refer to
- Through Pos (When the "SA Adjust Sensor U" (Transparent sensor) or the "SA Main
PCB" is replaced.)
- Reflect Pos (When the "SA Adjust Sensor L" (Reflective sensor) or the "SA Main PCB" is
replaced.)

(2) Sensor sensitivity adjustment (Factory mode)

Since Factory mode menu includes essential items that can affect the printing
accuracy, etc, DO NOT change the factory set values unless otherwise required.
- Do not turn OFF the power of the printer until you finish the adjustment. If
it is turned OFF, you need to repeat the adjustment from the beginning.
- The value adjusted here is retained until you change it with the same
procedure. Even if you perform initialization by selecting "Test Mode" main
menu, "Factory Default" submenu and then "Yes", the changed value is
not returned to the initial value set at the factory.
Perform sensitivity adjustment for each sensor with the following submenu.
