5.1.1 Servicing Adjustment Item List

The adjustment items of this product are as follows. For details of the adjustment items, refer to the detailed procedures and sketches of the adjustment items.
Function Item
Destination data At the time of Main board replacement, this
input adjustment is made to write the board common
information on a destination basis.
Head ID input At the time of head replacement, this adjustment is
made to correct head manufacturing variations and
eliminate the individual differences of print quality.
CR variation When the Main board, CR motor or PSB/PSE
correction board is changed individually, this adjustment is
made to write the maximum correction value to
prevent the occurrence of damage to the motor at
the time of CR motor heat generation.
However, when the CR shaft is changed together
with the above part, this adjustment is made to
measure the manufacturing variations of the CR
motor and PSB/PSE board, utilize the motor
capability to the maximum for motor heat
generation control, and prevent the motor from
being damaged by CR motor heat generation.
PG adjustment This adjustment is made to install the Front and
Rear CR guide shafts in parallel to the print surface
and to secure the predetermined clearance from the
print surface in the PG 0 position.

Main board.
