Correction
When the Main Board, CR Motor or PSB/PSE Board is replaced
individually, this adjustment is made to write the maximum
offset to prevent the occurrence of damage to the motor at the
time of CR Motor heat generation.
However, when the CR Guide Shaft is replaced 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.
Select and execute this function in the exclusive servicing program to
save the offset into the EEPROM.
