4 Static electricity attack Modified Head earth plate (M507834_02) to prevent head attack by static
electricity charged in media when media jam occurred.
However, static electricity may attacks to the slider when the operator touched
the slider part to remove the media.
Please advice to the customers that discharge by touching the metal part of the
machine other than slider before touching the slider or head, and remove the
media gently without making static electricity.
5 Replace head associated parts in the condi-
tion of electric charge remains. When replace the head and PCB with electric charge remains in 42V circuit,
head and PCB damage may increase.
Before replacement, make sure to check if electric charge is not remaining
inside of PCB when turning off the power each time.
For replacement procedure and precautions, please refer to the attached docu-
ment "Electric charge checking when replace the head and PCB."
Also to shorten the replacement time, resistance has been added to the Main
PCB and countermeasure of electric discharge also been added.
