1. To prevent the nozzle orifice plate from drying and accumulation of dust while the
printer is transported or stored, a "nozzle rubber seal" was installed in the factory
prior to shipment. Remove the "nozzle rubber seal" at the time of printer
installation/test run/adjustment.
2. The "nozzle rubber seal" prevents the orifice plate from drying and accumulation
of dust. When shutting down the printer, it is recommended that you install the
nozzle rubber seal between the orifice plate and charge electrode to assure easy
startup of the printer later.
Usage precautions:
1 Store the nozzle rubber seal in a vinyl bag or similar to prevent it from
collecting dirt and dust.
2 Before installing the nozzle rubber seal, be sure to clean it with the
makeup ink.
3 When installing the nozzle rubber seal, be careful not to deform the
charge electrode.
