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

 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.
