Ink System Supply Assy (Ink Supply Unit w/ Printhead)
 When removing/installing the Printhead, move the Carriage Assy to the center of the printer, and place the Spacer (about 5 mm) between the
Carriage Assy and Star Wheel Assy in order to prevent the CR Guide Frame and Main Frame from being deformed. (See " Printhead (p42)".)
 To prevent ink leakage, make sure not to separate the ink tubes from the I/C Holder Unit by removing the screws (x2) in section A shown above.
Loosening the screws even just once will cause ink leakage, therefore, make sure to replace the Ink System Supply Assy with a new one.
When installing the Ink System Supply Assy, see " Printhead (p42)" and " Ink Supply Unit (p42)".
Do not remove.

Printhead
 To replace the Printhead, it is necessary to disconnect the joint section of the Printhead and the ink tubes of the Ink Supply Unit. Before
disconnecting the joint section, perform “Ink Pressure Release” in advance. (See "2.2.1 Caution when Replacing the Printhead/Ink Supply Unit
(p27)" and " Ink Supply Unit (p42)".)
 When disconnecting the joint section of the ink tubes of the Ink Supply Unit and the Printhead, ink may slightly spill over from the ink tubes
even if “Ink Pressure Release” has been performed. To prevent the inside of the printer being made dirty by the spilling ink, make sure to attach
tape at the joint section of the ink tube when disconnecting the joint section of the ink tube of the Ink Supply Unit and the Printhead.
(See " Ink Supply Unit (p42)".)
 When disconnecting the ink tubes from the Printhead, make sure to replace the rubber packing between the ink tubes and the Printhead with a
new one in order to prevent ink leakage.
 When removing/installing the Printhead, move the Carriage Assy to the center of the printer, and place the Spacer (about 5 mm) between the
Carriage Assy and Star Wheel Assy in order to prevent the CR Guide Frame and Main Frame from being deformed.
 Tighten the screws in the order indicated in the figure above.
 After installing the Printhead, make sure to connect the ink tubes to the Printhead. (See " Ink Supply Unit (p42)".)
When replacing the Printhead, make sure to perform "3.2.7 Ink Leak Check (p79)" and
