Media width adjustment dial
The head pressure varies according to the width of the media being printed.
The head pressure balance must be adjusted according to media width so
that constant head pressure is applied to the head. With this printer, it can
be adjusted easily by turning the media width adjustment dial.
If the printing is blurred or lightly printed on one side or the media moves in
a zigzag pattern adjust the head pressure balance.
After making an adjustment, confirm the output quality with a test print.
