3-7. Adjustment (Transparent/Reflective Sensor)

When one of the following parts is replaced with a new one, perform sensor position adjustment
and sensor sensitivity adjustment as shown in the table below.
Parts replaced
SA Main PCB
SA TRA Sen PCB
(Transparent sensor)
SA Ref Sensor PCB
(Reflective sensor)

(1) Sensor position adjustment (Factory mode)

In Factory mode, perform the following sensor position adjustment. For the adjustment
procedure, refer to the following "Refer to" column.
Submenu
Through Pos
Reflect Pos

(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 the
power is turned OFF before finishing, 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 here
does not return to the initial value set at the factory.
Perform the sensitivity adjustment for each sensor with the following submenu. For the
adjustment procedure, refer to the following "Refer to" column.
