1. Make sure of the installing condition and correct it if there is any gap. (See Fig.
4-59.)
2. Install the Head FFC to the Printhead. (See 4.2.5.1 Printhead Step5 (p134).)
3. Install the Printhead to the Carriage Unit, and secure it as follows:
3-1. Place the hand on the center of the Printhead, and align the screws (x3)
with the screw holes to temporary tighten the screws 1 and 2 alternately
by 90 degrees slowly while pressing the Printhead in the direction of the
arrow shown in
Fig. 4-60.
3-2. Tighten the screw 3 to the same level as the screws 1 and 2 before
completely tighten them.
3-3. Tighten the screws slowly by 90 degrees in the order shown in Fig. 4-60
to secure the Printhead.
Figure 4-60. Assembling the Printhead (1)
When tightening the screws that secure the Printhead; to avoid
burring the slot, first align the screw to the hole, and turn it to
the left slightly to engage the threaded parts of the screw and
the hole correctly, then tighten it.
Make sure to follow the specified tightening torque.
When securing the Printhead, make sure to observe strictly the
following. Otherwise, the Printhead may be secured at an
angle, which may adversely affect the print quality.

If the SEAL JOINT,H shown in
Fig. 4-61
is once removed, be sure
to replace it with a new one.
Make sure to follow the steps below for connecting the Ink Supply
Tube Assy to the Printhead in order to prevent ink leakage.
The SEAL JOINT,Hs easily stick together. Therefore, it is
recommended to keep them in the Shipping Cleaning Liquid
“CR06A” (Parts number: 6104713 or 6104714) when storing
them in order to avoid them from getting stuck together.
When installing the SEAL JOINT,H, make sure to align its
holes with the ink supply holes on the Printhead. (
See
"Assembling the Printhead" Step4 (p137).)
Do not attach the SEAL JOINT,H to the Ink Supply Tube Assy
before connecting the Ink Supply Tube Assy to the Printhead or
otherwise cause the SEAL JOINT,H to attach improperly. This
will reduces adhesion between the Printhead and the Ink Supply
Tube Assy, and may result in ink leakage.

Do not attach the SEAL JOINT,H to
the Ink Supply Tube Assy before
connecting the tube to the Printhead.
Doing so causes the SEAL
JOINT,H to attach improperly and
may result in ink leakage.
Improperly attached SEAL JOINT,H
