Long-Term Shutdown - Hitachi UX Twin-Nozzle Technical Manual

6.15 Long-term Shutdown

● A special work is required to perform the Long-term Shutdown procedure. It is
recommended to contact your local distributor and ask for the work. Should you
desire to conduct the work by yourself, the cautions must be fully understood
beforehand. It is recommended to contact the local distributor and ask for an advice
even you desire to conduct it by yourself, too.
● Even the Long-term shutdown is conducted, ink fixing may occur in the circulation
system depending on the ink or the storage temperature or the storage period.
It is strongly recommended to contact your local distributor and ask for the work
when you conduct "Startup process after long-term shutdown", especially in case the
storage temperature is high (30 degrees Celsius or more) or the storage period
exceeds 6 months.
● To secure safety, make sure to follow the procedures explained in "6.15.2 Startup
process after long-term shutdown".
● When the IJ Printer was left for a period of time without conducting Long-term
shutdown, make sure to follow the procedures explained in "6.15.2 Startup process
after long-term shutdown".
● In "6.15.2 Startup process after long-term shutdown", should the circulation system
be operated continuously when the printer does not operate normally, the pressure in
the recovery line would be increased and it is going to be dangerous. There is a
possibility that the ink is ejected from the nozzle strongly or the ink is reversely
ejected from the gutter strongly. In such cases, stop the printer operation
immediately and contact the local distributor.
