5.15.1. Process prior to Long-term Shutdown 
This section describes the procedure for the process prior to long-term shutdown. 
 
(1) Overview 
 
● Store the unit at as low temperature as possible. 
● This process is not necessary if the unit can be operated at least once within the period listed in 
the table on the section indicated below.   
For the operating time in this case, see "1.2.5. Cautions on Operating Time When Unit Is in 
Service" in the Instruction Manual and the handling guidance of each ink. 
● Depending on the storage temperature and storage period of ink, remaining ink components 
may become stuck in the circulation system even if the process is performed prior to long-term 
shutdown. 
● If the unit is left unused over the above period without the process performed prior to long-term 
shutdown, check the state according to 
 
Operation check in "5.15.2. Process after Long-
term Shutdown". If you have any problem, contact your nearest local distributor. 
 
This is a storage process performed when the IJ Printer is shut down for a period of time longer than those 
listed in the table below. The storage process means removal of the ink in the ink circulation system and 
washing it with makeup.
