When turning off the main power switch, note the following. 
●  Normally, press the STOP switch instead of the main power switch to turn off the power at the end of 
operation. 
●  If the unit will not be used for a long time, turn OFF the main power switch. 
●  Do not turn OFF the main power switch while ink is being ejected, except for an emergency. 
(See "Chapter 14. Emergency Procedures".) 
●  Note that the power-on method varies depending on the turn-off method. 
 
Relationship between the turn-off method and the power-on method 
When turning OFF the main power switch after 
stopping the unit by the STOP switch 
Turn ON the main power switch and press the ON 
switch for about two seconds to turn on the 
power. 
When turning OFF the main power switch 
without using the STOP switch 
Turn ON the main power switch to turn on the 
power. 
 
● The "nozzle rubber seal" prevents the nozzle orifice from being dried and dust from 
attaching to the plate. When the unit will not be used for several days over a holiday, etc., it 
is recommended that the nozzle rubber seal be installed between the nozzle orifice and 
charge electrode at shutdown. 
 
 
 
-  Store the nozzle rubber seal in a plastic bag, etc., to protect it from dirt and dust. 
-  Install the nozzle rubber seal after cleaning it with makeup. 
-  Do not deform the charge electrode when installing the nozzle rubber seal.
