2.2 Shutdown

Shutdown
Complete the ink stop process by performing the following steps. If you turn OFF
the power without performing the ink stop process, the operation management
information (operating time and print count) and count update will not be stored into
memory. When the count function is used, you will have to set the count update
(initial value) again when the printer is powered ON.
1. Press the [Shut down] key.
The confirmation screen then opens.
2. Press the [Shut down] key.
Wait until the status changes from "Stopping" to "Stop".
3. Remove the print head cover and clean the print head.
Perform cleaning by pouring makeup ink over the area to be cleaned. Rinse
the orifice plate, charge electrode, deflection electrodes, gutter, and mounting
base to clean them. (Also refer to
*1. Use wiping paper to thoroughly wipe the makeup ink from the surfaces of the parts
(including the mounting base) and allow them to dry.
*2. The "nozzle rubber seal" assures dryness of the orifice plate and prevents
accumulation of dust. For easier startup of the printer, it is recommended that you
install the "nozzle rubber seal" between the orifice plate and charge electrode when
the printer is not used. (Refer to the next page.)
4. If the print head cover is dirty, apply makeup ink and clean it.
*1 Clean the portion soiled with splatter from printing or ejecting the ink.
*2 After cleaning, wipe off the makeup ink with wiping paper. For cleaning inside the
cover, use tweezers to hold the wiping paper.
