When the carriage unit installation completes, move the unit right and left to check that it does
not fall down from the rail.
• If the ink tube falls down, the ink tube is loosely attached on the left of the carriage unit.
Remove the bracket to secure the ink tubes and pull the ink tube from the left of the carriage
unit as possible to remove the looseness.
Before you turn the machine on, check the position of the horizontal encoder strip on the left.
• If the encoder strip is up on the bracket as shown at [A], pull it forward and down so it is in
front of the bracket as shown at [B].
• If the machine is turned on with the strip positioned as shown at [A], the movement of the
carriage unit may scratch the surface of the encoder strip.
